9 Managing Diagnostic Data

Oracle Database includes an advanced fault diagnosability infrastructure for collecting and managing diagnostic data. Diagnostic data includes the trace files, dumps, and core files that are also present in previous releases, plus new types of diagnostic data that enable customers and Oracle Support to identify, investigate, track, and resolve problems quickly and effectively.

9.1 About the Oracle Database Fault Diagnosability Infrastructure

Oracle Database includes a fault diagnosability infrastructure for preventing, detecting, diagnosing, and resolving database problems.

  • Fault Diagnosability Infrastructure Overview
    The fault diagnosability infrastructure aids in preventing, detecting, diagnosing, and resolving problems. The problems that are targeted in particular are critical errors such as those caused by code bugs, metadata corruption, and customer data corruption.
  • Incidents and Problems
    A problem is a critical error in a database instance, Oracle Automatic Storage Management (Oracle ASM) instance, or other Oracle product or component. An incident is a single occurrence of a problem.
  • Fault Diagnosability Infrastructure Components
    The fault diagnosability infrastructure consists of several components, including the Automatic Diagnostic Repository (ADR), various logs, trace files, the Enterprise Manager Support Workbench, and the ADRCI Command-Line Utility.
  • Structure, Contents, and Location of the Automatic Diagnostic Repository
    The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database. It is therefore available for problem diagnosis when the database is down.

9.1.1 Fault Diagnosability Infrastructure Overview

The fault diagnosability infrastructure aids in preventing, detecting, diagnosing, and resolving problems. The problems that are targeted in particular are critical errors such as those caused by code bugs, metadata corruption, and customer data corruption.

When a critical error occurs, it is assigned an incident number, and diagnostic data for the error (such as trace files) are immediately captured and tagged with this number. The data is then stored in the Automatic Diagnostic Repository (ADR)—a file-based repository outside the database—where it can later be retrieved by incident number and analyzed.

The goals of the fault diagnosability infrastructure are the following:

  • First-failure diagnosis

  • Problem prevention

  • Limiting damage and interruptions after a problem is detected

  • Reducing problem diagnostic time

  • Reducing problem resolution time

  • Simplifying customer interaction with Oracle Support

The keys to achieving these goals are the following technologies:

  • Automatic capture of diagnostic data upon first failure—For critical errors, the ability to capture error information at first-failure greatly increases the chance of a quick problem resolution and reduced downtime. An always-on memory-based tracing system proactively collects diagnostic data from many database components, and can help isolate root causes of problems. Such proactive diagnostic data is similar to the data collected by airplane "black box" flight recorders. When a problem is detected, alerts are generated and the fault diagnosability infrastructure is activated to capture and store diagnostic data. The data is stored in a repository that is outside the database (and therefore available when the database is down), and is easily accessible with command line utilities and Oracle Enterprise Manager Cloud Control (Cloud Control).

  • Standardized trace formats—Standardizing trace formats across all database components enables DBAs and Oracle Support personnel to use a single set of tools for problem analysis. Problems are more easily diagnosed, and downtime is reduced.

  • Health checks—Upon detecting a critical error, the fault diagnosability infrastructure can run one or more health checks to perform deeper analysis of a critical error. Health check results are then added to the other diagnostic data collected for the error. Individual health checks look for data block corruptions, undo and redo corruption, data dictionary corruption, and more. As a DBA, you can manually invoke these health checks, either on a regular basis or as required.

  • Incident packaging service (IPS) and incident packages—The IPS enables you to automatically and easily gather the diagnostic data—traces, dumps, health check reports, and more—pertaining to a critical error and package the data into a zip file for transmission to Oracle Support. Because all diagnostic data relating to a critical error are tagged with that error's incident number, you do not have to search through trace files and other files to determine the files that are required for analysis; the incident packaging service identifies the required files automatically and adds them to the zip file. Before creating the zip file, the IPS first collects diagnostic data into an intermediate logical structure called an incident package (package). Packages are stored in the Automatic Diagnostic Repository. If you choose to, you can access this intermediate logical structure, view and modify its contents, add or remove additional diagnostic data at any time, and when you are ready, create the zip file from the package. After these steps are completed, the zip file is ready to be uploaded to Oracle Support.

  • Data Recovery Advisor—The Data Recovery Advisor integrates with database health checks and RMAN to display data corruption problems, assess the extent of each problem (critical, high priority, low priority), describe the impact of a problem, recommend repair options, conduct a feasibility check of the customer-chosen option, and automate the repair process.

  • SQL Test Case Builder—For many SQL-related problems, obtaining a reproducible test case is an important factor in problem resolution speed. The SQL Test Case Builder automates the sometimes difficult and time-consuming process of gathering as much information as possible about the problem and the environment in which it occurred. After quickly gathering this information, you can upload it to Oracle Support to enable support personnel to easily and accurately reproduce the problem.

9.1.2 Incidents and Problems

A problem is a critical error in a database instance, Oracle Automatic Storage Management (Oracle ASM) instance, or other Oracle product or component. An incident is a single occurrence of a problem.

  • About Incidents and Problems
    To facilitate diagnosis and resolution of critical errors, the fault diagnosability infrastructure introduces two concepts for Oracle Database: problems and incidents.
  • Incident Flood Control
    It is conceivable that a problem could generate dozens or perhaps hundreds of incidents in a short period of time. This would generate too much diagnostic data, which would consume too much space in the ADR and could possibly slow down your efforts to diagnose and resolve the problem. For these reasons, the fault diagnosability infrastructure applies flood control to incident generation after certain thresholds are reached.
  • Related Problems Across the Topology
    For any problem identified in a database instance, the diagnosability framework can identify related problems across the topology of your Oracle Database installation.

Parent topic: About the Oracle Database Fault Diagnosability Infrastructure

9.1.2.1 About Incidents and Problems

To facilitate diagnosis and resolution of critical errors, the fault diagnosability infrastructure introduces two concepts for Oracle Database: problems and incidents.

A problem is a critical error in a database instance, Oracle Automatic Storage Management (Oracle ASM) instance, or other Oracle product or component. Critical errors manifest as internal errors, such as ORA-00600, or other severe errors, such as ORA-07445 (operating system exception) or ORA-04031 (out of memory in the shared pool). Problems are tracked in the ADR. Each problem has a problem key, which is a text string that describes the problem. It includes an error code (such as ORA 600) and in some cases, one or more error parameters.

An incident is a single occurrence of a problem. When a problem (critical error) occurs multiple times, an incident is created for each occurrence. Incidents are timestamped and tracked in the Automatic Diagnostic Repository (ADR). Each incident is identified by a numeric incident ID, which is unique within the ADR. When an incident occurs, the database:

  • Makes an entry in the alert log.

  • Sends an incident alert to Cloud Control.

  • Gathers first-failure diagnostic data about the incident in the form of dump files (incident dumps).

  • Tags the incident dumps with the incident ID.

  • Stores the incident dumps in an ADR subdirectory created for that incident.

Diagnosis and resolution of a critical error usually starts with an incident alert. Incident alerts are displayed on the Cloud Control Database Home page or Oracle Automatic Storage Management Home page. The Database Home page also displays in its Related Alerts section any critical alerts in the Oracle ASM instance or other Oracle products or components. After viewing an alert, you can then view the problem and its associated incidents with Cloud Control or with the ADRCI command-line utility.

9.1.2.2 Incident Flood Control

It is conceivable that a problem could generate dozens or perhaps hundreds of incidents in a short period of time. This would generate too much diagnostic data, which would consume too much space in the ADR and could possibly slow down your efforts to diagnose and resolve the problem. For these reasons, the fault diagnosability infrastructure applies flood control to incident generation after certain thresholds are reached.

A flood-controlled incident is an incident that generates an alert log entry, is recorded in the ADR, but does not generate incident dumps. Flood-controlled incidents provide a way of informing you that a critical error is ongoing, without overloading the system with diagnostic data. You can choose to view or hide flood-controlled incidents when viewing incidents with Cloud Control or the ADRCI command-line utility.

Threshold levels for incident flood control are predetermined and cannot be changed. They are defined as follows:

  • After five incidents occur for the same problem key in one hour, subsequent incidents for this problem key are flood-controlled. Normal (non-flood-controlled) recording of incidents for that problem key begins again in the next hour.

  • After 25 incidents occur for the same problem key in one day, subsequent incidents for this problem key are flood-controlled. Normal recording of incidents for that problem key begins again on the next day.

In addition, after 50 incidents for the same problem key occur in one hour, or 250 incidents for the same problem key occur in one day, subsequent incidents for this problem key are not recorded at all in the ADR. In these cases, the database writes a message to the alert log indicating that no further incidents will be recorded. As long as incidents continue to be generated for this problem key, this message is added to the alert log every ten minutes until the hour or the day expires. Upon expiration of the hour or day, normal recording of incidents for that problem key begins again.

Parent topic: Incidents and Problems

9.1.2.3 Related Problems Across the Topology

For any problem identified in a database instance, the diagnosability framework can identify related problems across the topology of your Oracle Database installation.

In a single instance environment, a related problem could be identified in the local Oracle ASM instance. In an Oracle RAC environment, a related problem could be identified in any database instance or Oracle ASM instance on any other node. When investigating problems, you are able to view and gather information on any related problems.

A problem is related to the original problem if it occurs within a designated time period or shares the same execution context identifier. An execution context identifier (ECID) is a globally unique identifier used to tag and track a single call through the Oracle software stack, for example, a call to Oracle Fusion Middleware that then calls into Oracle Database to retrieve data. The ECID is typically generated in the middle tier and is passed to the database as an Oracle Call Interface (OCI) attribute. When a single call has failures on multiple tiers of the Oracle software stack, problems that are generated are tagged with the same ECID so that they can be correlated. You can then determine the tier on which the originating problem occurred.

9.1.3 Fault Diagnosability Infrastructure Components

The fault diagnosability infrastructure consists of several components, including the Automatic Diagnostic Repository (ADR), various logs, trace files, the Enterprise Manager Support Workbench, and the ADRCI Command-Line Utility.

  • Automatic Diagnostic Repository (ADR)
    The ADR is a file-based repository for database diagnostic data such as traces, dumps, the alert log, health monitor reports, and more. It has a unified directory structure across multiple instances and multiple products.
  • Alert Log
    The alert log is an XML file that is a chronological log of messages and errors.
  • Trace Files, Dumps, and Core Files
    Trace files, dumps, and core files contain diagnostic data that are used to investigate problems. They are stored in the ADR.
  • DDL Log
    The data definition language (DDL) log is a file that has the same format and basic behavior as the alert log, but it only contains the DDL statements issued by the database.
  • Debug Log
    An Oracle Database component can detect conditions, states, or events that are unusual, but which do not inhibit correct operation of the detecting component. The component can issue a warning about these conditions, states, or events. The debug log is a file that records these warnings.
  • Other ADR Contents
    In addition to files mentioned in the previous sections, the ADR contains health monitor reports, data repair records, SQL test cases, incident packages, and more. These components are described later in the chapter.
  • Enterprise Manager Support Workbench
    The Enterprise Manager Support Workbench (Support Workbench) is a facility that enables you to investigate, report, and in some cases, repair problems (critical errors), all with an easy-to-use graphical interface.
  • ADRCI Command-Line Utility
    The ADR Command Interpreter (ADRCI) is a utility that enables you to investigate problems, view health check reports, and package first-failure diagnostic data, all within a command-line environment.

Parent topic: About the Oracle Database Fault Diagnosability Infrastructure

9.1.3.1 Automatic Diagnostic Repository (ADR)

The ADR is a file-based repository for database diagnostic data such as traces, dumps, the alert log, health monitor reports, and more. It has a unified directory structure across multiple instances and multiple products.

The database, Oracle Automatic Storage Management (Oracle ASM), the listener, Oracle Clusterware, and other Oracle products or components store all diagnostic data in the ADR. Each instance of each product stores diagnostic data underneath its own home directory within the ADR. For example, in an Oracle Real Application Clusters environment with shared storage and Oracle ASM, each database instance and each Oracle ASM instance has an ADR home directory. ADR's unified directory structure, consistent diagnostic data formats across products and instances, and a unified set of tools enable customers and Oracle Support to correlate and analyze diagnostic data across multiple instances. With Oracle Clusterware, each host node in the cluster has an ADR home directory.

Note:

Because all diagnostic data, including the alert log, are stored in the ADR, the initialization parameters BACKGROUND_DUMP_DEST and USER_DUMP_DEST are deprecated. They are replaced by the initialization parameter DIAGNOSTIC_DEST, which identifies the location of the ADR.

See Also:

"Structure, Contents, and Location of the Automatic Diagnostic Repository" for more information on the DIAGNOSTIC_DEST parameter and on ADR homes.

Parent topic: Fault Diagnosability Infrastructure Components

9.1.3.2 Alert Log

The alert log is an XML file that is a chronological log of messages and errors.

There is one alert log in each ADR home. Each alert log is specific to its component type, such as database, Oracle ASM, listener, and Oracle Clusterware.

For the database, the alert log includes messages about the following:

  • Critical errors (incidents)

  • Administrative operations, such as starting up or shutting down the database, recovering the database, creating or dropping a tablespace, and others.

  • Errors during automatic refresh of a materialized view

  • Other database events

You can view the alert log in text format (with the XML tags stripped) with Cloud Control and with the ADRCI utility. There is also a text-formatted version of the alert log stored in the ADR for backward compatibility. However, Oracle recommends that any parsing of the alert log contents be done with the XML-formatted version, because the text format is unstructured and may change from release to release.

9.1.3.3 Trace Files, Dumps, and Core Files

Trace files, dumps, and core files contain diagnostic data that are used to investigate problems. They are stored in the ADR.

  • Trace Files
    Each server and background process can write to an associated trace file. Trace files are updated periodically over the life of the process and can contain information on the process environment, status, activities, and errors. In addition, when a process detects a critical error, it writes information about the error to its trace file.
  • Dumps
    A dump is a specific type of trace file. A dump is typically a one-time output of diagnostic data in response to an event (such as an incident), whereas a trace tends to be continuous output of diagnostic data.
  • Core Files
    A core file contains a memory dump, in an all-binary, port-specific format.

Parent topic: Fault Diagnosability Infrastructure Components

9.1.3.3.1 Trace Files

Each server and background process can write to an associated trace file. Trace files are updated periodically over the life of the process and can contain information on the process environment, status, activities, and errors. In addition, when a process detects a critical error, it writes information about the error to its trace file.

The SQL trace facility also creates trace files, which provide performance information on individual SQL statements. You can enable SQL tracing for a session or an instance.

Trace file names are platform-dependent. Typically, database background process trace file names contain the Oracle SID, the background process name, and the operating system process number, while server process trace file names contain the Oracle SID, the string "ora", and the operating system process number. The file extension is .trc. An example of a server process trace file name is orcl_ora_344.trc. Trace files are sometimes accompanied by corresponding trace metadata (.trm) files, which contain structural information about trace files and are used for searching and navigation.

Oracle Database includes tools that help you analyze trace files. For more information on application tracing, SQL tracing, and tracing tools, see Oracle Database SQL Tuning Guide.

9.1.3.3.2 Dumps

A dump is a specific type of trace file. A dump is typically a one-time output of diagnostic data in response to an event (such as an incident), whereas a trace tends to be continuous output of diagnostic data.

When an incident occurs, the database writes one or more dumps to the incident directory created for the incident. Incident dumps also contain the incident number in the file name.

9.1.3.3.3 Core Files

A core file contains a memory dump, in an all-binary, port-specific format.

Core file names include the string "core" and the operating system process ID. Core files are useful to Oracle Support engineers only. Core files are not found on all platforms.

9.1.3.4 DDL Log

The data definition language (DDL) log is a file that has the same format and basic behavior as the alert log, but it only contains the DDL statements issued by the database.

The DDL log is created only for the RDBMS component and only if the ENABLE_DDL_LOGGING initialization parameter is set to TRUE. When this parameter is set to FALSE, DDL statements are not included in any log.

The DDL log contains one log record for each DDL statement issued by the database. The DDL log is included in IPS incident packages.

There are two DDL logs that contain the same information. One is an XML file, and the other is a text file. The DDL log is stored in the log/ddl subdirectory of the ADR home.

See Also:

Oracle Database Reference for more information about the ENABLE_DDL_LOGGING initialization parameter

Parent topic: Fault Diagnosability Infrastructure Components

9.1.3.5 Debug Log

An Oracle Database component can detect conditions, states, or events that are unusual, but which do not inhibit correct operation of the detecting component. The component can issue a warning about these conditions, states, or events. The debug log is a file that records these warnings.

These warnings recorded in the debug log are not serious enough to warrant an incident or a write to the alert log. They do warrant a record in a log file because they might be needed to diagnose a future problem.

The debug log has the same format and basic behavior as the alert log, but it only contains information about possible problems that might need to be corrected.

The debug log reduces the amount of information in the alert log and trace files. It also improves the visibility of debug information.

The debug log is included in IPS incident packages. The debug log's contents are intended for Oracle Support. Database administrators should not use the debug log directly.

Note:

Because there is a separate debug log starting with Oracle Database 12c, the alert log and the trace files are streamlined. They now contain fewer warnings of the type that are recorded in the debug log.

9.1.3.6 Other ADR Contents

In addition to files mentioned in the previous sections, the ADR contains health monitor reports, data repair records, SQL test cases, incident packages, and more. These components are described later in the chapter.

9.1.3.7 Enterprise Manager Support Workbench

The Enterprise Manager Support Workbench (Support Workbench) is a facility that enables you to investigate, report, and in some cases, repair problems (critical errors), all with an easy-to-use graphical interface.

The Support Workbench provides a self-service means for you to gather first-failure diagnostic data, obtain a support request number, and upload diagnostic data to Oracle Support with a minimum of effort and in a very short time, thereby reducing time-to-resolution for problems. The Support Workbench also recommends and provides easy access to Oracle advisors that help you repair SQL-related problems, data corruption problems, and more.

9.1.3.8 ADRCI Command-Line Utility

The ADR Command Interpreter (ADRCI) is a utility that enables you to investigate problems, view health check reports, and package first-failure diagnostic data, all within a command-line environment.

You can then upload the package to Oracle Support. ADRCI also enables you to view the names of the trace files in the ADR, and to view the alert log with XML tags stripped, with and without content filtering.

For more information on ADRCI, see Oracle Database Utilities.

9.1.4 Structure, Contents, and Location of the Automatic Diagnostic Repository

The Automatic Diagnostic Repository (ADR) is a directory structure that is stored outside of the database. It is therefore available for problem diagnosis when the database is down.

The ADR root directory is known as ADR base. Its location is set by the DIAGNOSTIC_DEST initialization parameter. If this parameter is omitted or left null, the database sets DIAGNOSTIC_DEST upon startup as follows:

  • If environment variable ORACLE_BASE is set, DIAGNOSTIC_DEST is set to the directory designated by ORACLE_BASE.

  • If environment variable ORACLE_BASE is not set, DIAGNOSTIC_DEST is set to ORACLE_HOME/log.

Within ADR base, there can be multiple ADR homes, where each ADR home is the root directory for all diagnostic data—traces, dumps, the alert log, and so on—for a particular instance of a particular Oracle product or component. For example, in an Oracle Real Application Clusters environment with Oracle ASM, each database instance, Oracle ASM instance, and listener has an ADR home.

ADR homes reside in ADR base subdirectories that are named according to the product or component type. Figure 9-1 illustrates these top-level subdirectories.

Figure 9-1 Product/Component Type Subdirectories in the ADR

Description of Figure 9-1 follows
Description of "Figure 9-1 Product/Component Type Subdirectories in the ADR"

Note:

Additional subdirectories might be created in the ADR depending on your configuration. Some products automatically purge expired diagnostic data from ADR. For other products, you can use the ADRCI utility PURGE command at regular intervals to purge expired diagnostic data.

The location of each ADR home is given by the following path, which starts at the ADR base directory:

diag/product_type/product_id/instance_id

As an example, Table 9-1 lists the values of the various path components for an Oracle Database instance.

Table 9-1 ADR Home Path Components for Oracle Database

Path Component Value for Oracle Database

product_type

rdbms

product_id

DB_UNIQUE_NAME

instance_id

SID

For example, for a database with a SID and database unique name both equal to orclbi, the ADR home would be in the following location: 

ADR_base/diag/rdbms/orclbi/orclbi/

Similarly, the ADR home path for the Oracle ASM instance in a single-instance environment would be:

ADR_base/diag/asm/+asm/+asm/

ADR Home Subdirectories

Within each ADR home directory are subdirectories that contain the diagnostic data. Table 9-2 lists some of these subdirectories and their contents.

Other subdirectories of ADR home, which store incident packages, health monitor reports, logs other than the alert log (such as the DDL log and the debug log), and other information

Figure 9-2 illustrates the complete directory hierarchy of the ADR for a database instance.

Figure 9-2 ADR Directory Structure for a Database Instance

Description of Figure 9-2 follows
Description of "Figure 9-2 ADR Directory Structure for a Database Instance"

ADR in an Oracle Clusterware Environment

Oracle Clusterware uses ADR and has its own Oracle home and Oracle base. The ADR directory structure for Oracle Clusterware is different from that of a database instance. There is only one instance of Oracle Clusterware on a system, so Clusterware ADR homes use only a system's host name as a differentiator.

When Oracle Clusterware is configured, the ADR home uses crs for both the product type and the instance ID, and the system host name is used for the product ID. Thus, on a host named dbprod01, the CRS ADR home would be: 

ADR_base/diag/crs/dbprod01/crs/

See Also:

Oracle Clusterware Administration and Deployment Guide

ADR in an Oracle Real Application Clusters Environment

In an Oracle Real Application Clusters (Oracle RAC) environment, each node can have ADR base on its own local storage, or ADR base can be set to a location on shared storage. You can use ADRCI to view aggregated diagnostic data from all instances on a single report.

ADR in Oracle Client

Each installation of Oracle Client includes an ADR for diagnostic data associated with critical failures in any of the Oracle Client components. The ADRCI utility is installed with Oracle Client so that you can examine diagnostic data and package it to enable it for upload to Oracle Support.

Viewing ADR Locations with the V$DIAG_INFO View

9.2 Investigating, Reporting, and Resolving a Problem

You can use the Enterprise Manager Support Workbench (Support Workbench) to investigate and report a problem (critical error), and in some cases, resolve the problem. You can use a "roadmap" that summarizes the typical set of tasks that you must perform.

Note:

The tasks described in this section are all Cloud Control–based. You can also accomplish all of these tasks (or their equivalents) with the ADRCI command-line utility, with PL/SQL packages such as DBMS_HM and DBMS_SQLDIAG, and with other software tools. See Oracle Database Utilities for more information on the ADRCI utility, and see Oracle Database PL/SQL Packages and Types Reference for information on PL/SQL packages.

9.2.4 Task 3: (Optional) Gather Additional Diagnostic Information

You can perform the following activities to gather additional diagnostic information for a problem. This additional information is then automatically included in the diagnostic data uploaded to Oracle Support. If you are unsure about performing these activities, then check with your Oracle Support representative.

Parent topic: Investigating, Reporting, and Resolving a Problem

9.2.5 Task 4: (Optional) Create a Service Request

At this point, you can create an Oracle Support service request and record the service request number with the problem information.

If you choose to skip this task, then the Support Workbench will automatically create a draft service request for you in "Task 5: Package and Upload Diagnostic Data to Oracle Support".

To create a service request:

  1. From the Enterprise menu, select My Oracle Support, then Service Requests.

    The My Oracle Support Login and Registration page appears.

  2. Log in to My Oracle Support and create a service request in the usual manner.

    (Optional) Remember the service request number (SR#) for the next step.

  3. (Optional) Return to the Problem Details page, and then do the following:

    1. In the Summary section, click the Edit button that is adjacent to the SR# label.

    2. Enter the SR#, and then click OK.

    The SR# is recorded in the Problem Details page. This is for your reference only. See "Viewing Problems with the Support Workbench" for information about returning to the Problem Details page.

Parent topic: Investigating, Reporting, and Resolving a Problem

9.2.6 Task 5: Package and Upload Diagnostic Data to Oracle Support

For this task, you use the quick packaging process of the Support Workbench to package and upload the diagnostic information for the problem to Oracle Support.

Quick packaging has a minimum of steps, organized in a guided workflow (a wizard). The wizard assists you with creating an incident package (package) for a single problem, creating a zip file from the package, and uploading the file. With quick packaging, you are not able to edit or otherwise customize the diagnostic information that is uploaded. However, quick packaging is the more direct, straightforward method to package and upload diagnostic data.

To edit or remove sensitive data from the diagnostic information, enclose additional user files (such as application configuration files or scripts), or perform other customizations before uploading, you must use the custom packaging process, which is a more manual process and has more steps. See "Creating, Editing, and Uploading Custom Incident Packages" for instructions. If you choose to follow those instructions instead of the instructions here in Task 5, do so now and then continue with Task 6: Track the Service Request and Implement Any Repairs when you are finished.

Note:

The Support Workbench uses Oracle Configuration Manager to upload the diagnostic data. If Oracle Configuration Manager is not installed or properly configured, the upload may fail. In this case, a message is displayed with a request that you upload the file to Oracle Support manually. You can upload manually with My Oracle Support.

For more information about Oracle Configuration Manager, see Oracle Configuration Manager Installation and Administration Guide.

To package and upload diagnostic data to Oracle Support:

  1. On the Support Workbench Problem Details page, in the Investigate and Resolve section, click Quick Package.

    The Create New Package page of the Quick Packaging wizard appears.

    Note:

    See "Viewing Problems with the Support Workbench" for instructions for returning to the Problem Details page if you are not already there.

  2. (Optional) Enter a package name and description.
  3. Fill in any remaining fields on the page. If you have created a service request for this problem, then select the No option button for Create new Service Request (SR).

    If you select the Yes option button for Create new Service Request (SR), then the Quick Packaging wizard creates a draft service request on your behalf. You must later log in to My Oracle Support and fill in the details of the service request.

    Click Next.

    The Quick Packaging wizard displays a page indicating that it is processing the command to create a new package. When it finished, the Quick Packaging: View Contents page is displayed.

  4. Review the contents on the View Contents page, making a note of the size of the created package, then click Next.

    The Quick Packaging: View Manifest page appears.

  5. Review the information on this page, making a note of the location of the manifest (listed next to the heading Path). After you have reviewed the information, click Next.

    The Quick Packaging: Schedule page appears.

  6. Choose either Immediately, or Later. If you select Later, then you provide additional information about the time the package should be submitted to My Oracle Support. After you have made your choice and provided any necessary information, click Submit.

    The Processing: Packaging and Sending the Package progress page appears.

When the Quick Packaging wizard is complete, if a new draft service request was created, then the confirmation message contains a link to the draft service request in My Oracle Support in Cloud Control. You can review and edit the service request by clicking the link.

The package created by the Quick Packaging wizard remains available in the Support Workbench. You can then modify it with custom packaging operations (such as adding new incidents) and upload again at a later time. See "Viewing and Modifying Incident Packages".

9.2.7 Task 6: Track the Service Request and Implement Any Repairs

After uploading diagnostic information to Oracle Support, you might perform various activities to track the service request, to collect additional diagnostic information, and to implement repairs.

Among these activities are the following:

  • Adding an Oracle bug number to the problem information.

    To do so, on the Problem Details page, click the Edit button that is adjacent to the Bug# label. This is for your reference only.

  • Adding comments to the problem activity log.

    You may want to do this to share problem status or history information with other DBAs in your organization. For example, you could record the results of your conversations with Oracle Support. To add comments, complete the following steps:

    1. Access the Problem Details page for the problem, as described in "Viewing Problems with the Support Workbench".

    2. Click Activity Log to display the Activity Log subpage.

    3. In the Comment field, enter a comment, and then click Add Comment.

      Your comment is recorded in the activity log.

  • As new incidents occur, adding them to the package and reuploading.

    For this activity, you must use the custom packaging method described in "Creating, Editing, and Uploading Custom Incident Packages".

  • Running health checks.

    See "Running Health Checks with Health Monitor".

  • Running a suggested Oracle advisor to implement repairs.

    Access the suggested advisor in one of the following ways:

    • Problem Details page—In the Self-Service tab of the Investigate and Resolve section

    • Support Workbench home page—on the Checker Findings subpage

    • Incident Details page—on the Checker Findings subpage

9.4 Adding Problems Manually to the Automatic Diagnostic Repository

You can use Support Workbench in Cloud Control to manually add a problem to the ADR.

System-generated problems, such as critical errors generated internally to the database are automatically added to the Automatic Diagnostic Repository (ADR) and tracked in the Support Workbench.

From the Support Workbench, you can gather additional diagnostic data on these problems, upload diagnostic data to Oracle Support, and in some cases, resolve the problems, all with the easy-to-use workflow that is explained in "Investigating, Reporting, and Resolving a Problem".

There may be a situation in which you want to manually add a problem that you noticed to the ADR, so that you can put that problem through that same workflow. An example of such a situation might be a global database performance problem that was not diagnosed by Automatic Diagnostic Database Monitor (ADDM). The Support Workbench includes a mechanism for you to create and work with such a user-reported problem.

To create a user-reported problem:

  1. Access the Support Workbench home page.
  2. Under Related Links, click Create User-Reported Problem.

    The Create User-Reported Problem page appears.

    Description of create_user_reported_prob.gif follows

9.6 Finding Trace Files

Trace files are stored in the Automatic Diagnostic Repository (ADR), in the trace directory under each ADR home. To help you locate individual trace files within this directory, you can use data dictionary views. For example, you can find the path to your current session's trace file or to the trace file for each Oracle Database process.

To find the trace file for your current session:

  • Submit the following query:

    SELECT VALUE FROM V$DIAG_INFO WHERE NAME = 'Default Trace File';

    The full path to the trace file is returned.

To find all trace files for the current instance:

  • Submit the following query:

    SELECT VALUE FROM V$DIAG_INFO WHERE NAME = 'Diag Trace';

    The path to the ADR trace directory for the current instance is returned.

9.7 Running Health Checks with Health Monitor

You can run diagnostic checks on a database with Health Monitor.

  • About Health Monitor
    Oracle Database includes a framework called Health Monitor for running diagnostic checks on the database.
  • Running Health Checks Manually
    Health Monitor can run health checks manually either by using the DBMS_HM PL/SQL package or by using the Cloud Control interface, found on the Checkers subpage of the Advisor Central page.
  • Viewing Checker Reports
    After a checker has run, you can view a report of its execution. The report contains findings, recommendations, and other information. You can view reports using Cloud Control, the ADRCI utility, or the DBMS_HM PL/SQL package. The following table indicates the report formats available with each viewing method.
  • Health Monitor Views
    Instead of requesting a checker report, you can view the results of a specific checker run by directly querying the ADR data from which reports are created.
  • Health Check Parameters Reference
    Some health checks require parameters. Parameters with a default value of (none) are mandatory.

Parent topic: Managing Diagnostic Data

9.7.1 About Health Monitor

Oracle Database includes a framework called Health Monitor for running diagnostic checks on the database.

Parent topic: Running Health Checks with Health Monitor

9.7.1.1 About Health Monitor Checks

Health Monitor checks (also known as checkers, health checks, or checks) examine various layers and components of the database.

Health checks detect file corruptions, physical and logical block corruptions, undo and redo corruptions, data dictionary corruptions, and more. The health checks generate reports of their findings and, in many cases, recommendations for resolving problems. Health checks can be run in two ways:

  • Reactive—The fault diagnosability infrastructure can run health checks automatically in response to a critical error.

  • Manual—As a DBA, you can manually run health checks using either the DBMS_HM PL/SQL package or the Cloud Control interface. You can run checkers on a regular basis if desired, or Oracle Support may ask you to run a checker while working with you on a service request.

Health Monitor checks store findings, recommendations, and other information in the Automatic Diagnostic Repository (ADR).

Health checks can run in two modes:

  • DB-online mode means the check can be run while the database is open (that is, in OPEN mode or MOUNT mode).

  • DB-offline mode means the check can be run when the instance is available but the database itself is closed (that is, in NOMOUNT mode).

All the health checks can be run in DB-online mode. Only the Redo Integrity Check and the DB Structure Integrity Check can be used in DB-offline mode.

Note:

"Automatic Diagnostic Repository (ADR)"

Parent topic: About Health Monitor

9.7.1.2 Types of Health Checks

Health monitor runs several different types of checks.

Health monitor runs the following checks:

  • DB Structure Integrity Check—This check verifies the integrity of database files and reports failures if these files are inaccessible, corrupt or inconsistent. If the database is in mount or open mode, this check examines the log files and data files listed in the control file. If the database is in NOMOUNT mode, only the control file is checked.

  • Data Block Integrity Check—This check detects disk image block corruptions such as checksum failures, head/tail mismatch, and logical inconsistencies within the block. Most corruptions can be repaired using Block Media Recovery. Corrupted block information is also captured in the V$DATABASE_BLOCK_CORRUPTION view. This check does not detect inter-block or inter-segment corruption.

  • Redo Integrity Check—This check scans the contents of the redo log for accessibility and corruption, as well as the archive logs, if available. The Redo Integrity Check reports failures such as archive log or redo corruption.

  • Undo Segment Integrity Check—This check finds logical undo corruptions. After locating an undo corruption, this check uses PMON and SMON to try to recover the corrupted transaction. If this recovery fails, then Health Monitor stores information about the corruption in V$CORRUPT_XID_LIST. Most undo corruptions can be resolved by forcing a commit.

  • Transaction Integrity Check—This check is identical to the Undo Segment Integrity Check except that it checks only one specific transaction.

  • Dictionary Integrity Check—This check examines the integrity of core dictionary objects, such as tab$ and col$. It performs the following operations:

    • Verifies the contents of dictionary entries for each dictionary object.

    • Performs a cross-row level check, which verifies that logical constraints on rows in the dictionary are enforced.

    • Performs an object relationship check, which verifies that parent-child relationships between dictionary objects are enforced.

    The Dictionary Integrity Check operates on the following dictionary objects:

    tab$, clu$, fet$, uet$, seg$, undo$, ts$, file$, obj$, ind$, icol$, col$, user$, con$, cdef$, ccol$, bootstrap$, objauth$, ugroup$, tsq$, syn$, view$, typed_view$, superobj$, seq$, lob$, coltype$, subcoltype$, ntab$, refcon$, opqtype$, dependency$, access$, viewcon$, icoldep$, dual$, sysauth$, objpriv$, defrole$, and ecol$.

9.7.2 Running Health Checks Manually

Health Monitor can run health checks manually either by using the DBMS_HM PL/SQL package or by using the Cloud Control interface, found on the Checkers subpage of the Advisor Central page.

Parent topic: Running Health Checks with Health Monitor

9.7.2.1 Running Health Checks Using the DBMS_HM PL/SQL Package

The DBMS_HM procedure for running a health check is called RUN_CHECK.

  1. To call RUN_CHECK, supply the name of the check and a name for the run, as follows: 

    BEGIN
  DBMS_HM.RUN_CHECK('Dictionary Integrity Check', 'my_run');
END;
/

  2. To obtain a list of health check names, run the following query:

    SELECT name FROM v$hm_check WHERE internal_check='N';

    Your output is similar to the following:

    NAME
----------------------------------------------------------------
DB Structure Integrity Check
Data Block Integrity Check
Redo Integrity Check
Transaction Integrity Check
Undo Segment Integrity Check
Dictionary Integrity Check

Most health checks accept input parameters. You can view parameter names and descriptions with the V$HM_CHECK_PARAM view. Some parameters are mandatory while others are optional. If optional parameters are omitted, defaults are used. The following query displays parameter information for all health checks: 

SELECT c.name check_name, p.name parameter_name, p.type,
p.default_value, p.description
FROM v$hm_check_param p, v$hm_check c
WHERE p.check_id = c.id and c.internal_check = 'N'
ORDER BY c.name;

Input parameters are passed in the input_params argument as name/value pairs separated by semicolons (;). The following example illustrates how to pass the transaction ID as a parameter to the Transaction Integrity Check: 

BEGIN
  DBMS_HM.RUN_CHECK (
   check_name   => 'Transaction Integrity Check',
   run_name     => 'my_run',
   input_params => 'TXN_ID=7.33.2');
END;
/
9.7.2.2 Running Health Checks Using Cloud Control

Cloud Control provides an interface for running Health Monitor checkers.

To run a Health Monitor Checker using Cloud Control:

  1. Access the Database Home page.
  2. From the Performance menu, select Advisors Home.
  3. Click Checkers to view the Checkers subpage.
  4. In the Checkers section, click the checker you want to run.
  5. Enter values for input parameters or, for optional parameters, leave them blank to accept the defaults.
  6. Click OK, confirm your parameters, and click OK again.

9.7.3 Viewing Checker Reports

After a checker has run, you can view a report of its execution. The report contains findings, recommendations, and other information. You can view reports using Cloud Control, the ADRCI utility, or the DBMS_HM PL/SQL package. The following table indicates the report formats available with each viewing method.

9.7.3.4 Viewing Reports Using the ADRCI Utility

You can create and view Health Monitor checker reports using the ADRCI utility.

To create and view a checker report using ADRCI:

  1. Ensure that operating system environment variables (such as ORACLE_HOME) are set properly, and then enter the following command at the operating system command prompt:
    ADRCI

    The utility starts and displays the following prompt:

    adrci>>

    Optionally, you can change the current ADR home. Use the SHOW HOMES command to list all ADR homes, and the SET HOMEPATH command to change the current ADR home. See Oracle Database Utilities for more information.

  2. Enter the following command:
    show hm_run

    This command lists all the checker runs (stored in V$HM_RUN) registered in the ADR repository.

  3. Locate the checker run for which you want to create a report and note the checker run name. The REPORT_FILE field contains a file name if a report already exists for this checker run. Otherwise, generate the report with the following command:
    create report hm_run run_name
  4. To view the report, enter the following command:
    show report hm_run run_name

Note:

"Automatic Diagnostic Repository (ADR)"

Parent topic: Viewing Checker Reports

9.7.4 Health Monitor Views

Instead of requesting a checker report, you can view the results of a specific checker run by directly querying the ADR data from which reports are created.

This data is available through the views V$HM_RUN, V$HM_FINDING, and V$HM_RECOMMENDATION.

The following example queries the V$HM_RUN view to determine a history of checker runs: 

SELECT run_id, name, check_name, run_mode, src_incident FROM v$hm_run;

    RUN_ID NAME         CHECK_NAME                         RUN_MODE SRC_INCIDENT
---------- ------------ ---------------------------------- -------- ------------
         1 HM_RUN_1     DB Structure Integrity Check       REACTIVE            0
       101 HM_RUN_101   Transaction Integrity Check        REACTIVE         6073
       121 TXNCHK       Transaction Integrity Check        MANUAL              0
       181 HMR_tab$     Dictionary Integrity Check         MANUAL              0
          .
          .
          .
       981 Proct_ts$    Dictionary Integrity Check         MANUAL              0
      1041 HM_RUN_1041  DB Structure Integrity Check       REACTIVE            0
      1061 HM_RUN_1061  Data Block Integrity Check         REACTIVE         7418

The next example queries the V$HM_FINDING view to obtain finding details for the reactive data block check with RUN_ID 1061: 

SELECT type, description FROM v$hm_finding WHERE run_id = 1061;

TYPE          DESCRIPTION

9.8 Repairing SQL Failures with the SQL Repair Advisor

In the rare case that a SQL statement fails with a critical error, you can run the SQL Repair Advisor to try to repair the failed statement.

  • About the SQL Repair Advisor
    You run the SQL Repair Advisor after a SQL statement fails with a critical error.
  • Running the SQL Repair Advisor
    You run the SQL Repair Advisor from the Problem Details page of the Support Workbench.
  • Viewing, Disabling, or Removing a SQL Patch
    After you apply a SQL patch with the SQL Repair Advisor, you may want to view it to confirm its presence, disable it, or remove it. One reason to remove a patch is if you install a later release of Oracle Database that fixes the bug that caused the failure in the patched SQL statement.

Parent topic: Managing Diagnostic Data

9.8.1 About the SQL Repair Advisor

You run the SQL Repair Advisor after a SQL statement fails with a critical error.

The advisor analyzes the statement and in many cases recommends a patch to repair the statement. If you implement the recommendation, the applied SQL patch circumvents the failure by causing the query optimizer to choose an alternate execution plan for future executions.

Parent topic: Repairing SQL Failures with the SQL Repair Advisor

9.8.2 Running the SQL Repair Advisor

You run the SQL Repair Advisor from the Problem Details page of the Support Workbench.

Typically, you do so when you were already notified of a critical error caused by your SQL statement and that you followed the workflow described in "Investigating, Reporting, and Resolving a Problem".

To run the SQL Repair Advisor:

  1. Access the Problem Details page for the problem that pertains to the failed SQL statement.

    See "Viewing Problems with the Support Workbench" for instructions.

  2. In the Investigate and Resolve section, under the Resolve heading, click SQL Repair Advisor.

9.10.1.1 About Incident Packages

For the customized approach to uploading diagnostic data to Oracle Support, you first collect the data into an intermediate logical structure called an incident package (package).

A package is a collection of metadata that is stored in the Automatic Diagnostic Repository (ADR) and that points to diagnostic data files and other files both in and out of the ADR. When you create a package, you select one or more problems to add to the package. The Support Workbench then automatically adds to the package the problem information, incident information, and diagnostic data (such as trace files and dumps) associated with the selected problems. Because a problem can have many incidents (many occurrences of the same problem), by default only the first three and last three incidents for each problem are added to the package, excluding any incidents that are over 90 days old. You can change these default numbers on the Incident Packaging Configuration page of the Support Workbench.

After the package is created, you can add any type of external file to the package, remove selected files from the package, or edit selected files in the package to remove sensitive data. As you add and remove package contents, only the package metadata is modified.

When you are ready to upload the diagnostic data to Oracle Support, you first create a zip file that contains all the files referenced by the package metadata. You then upload the zip file through Oracle Configuration Manager.

Note:

If you do not have Oracle Configuration Manager installed and properly configured, then you must upload the zip file manually through My Oracle Support.

For more information about Oracle Configuration Manager, see Oracle Configuration Manager Installation and Administration Guide.

9.10.1.2 About Correlated Diagnostic Data in Incident Packages

To diagnose problem, it is sometimes necessary to examine not only diagnostic data that is directly related to the problem, but also diagnostic data that is correlated with the directly related data.

Diagnostic data can be correlated by time, by process ID, or by other criteria. For example, when examining an incident, it may be helpful to also examine an incident that occurred five minutes after the original incident. Similarly, while it is clear that the diagnostic data for an incident should include the trace file for the Oracle Database process that was running when the incident occurred, it might be helpful to also include trace files for other processes that are related to the original process.

Thus, when problems and their associated incidents are added to a package, any correlated incidents are added at the same time, with their associated trace files.

During the process of creating the physical file for a package, the Support Workbench calls upon the Incident Packaging Service to finalize the package. Finalizing means adding to the package any additional trace files that are correlated by time to incidents in the package, and adding other diagnostic information such as the alert log, health checker reports, SQL test cases, configuration information, and so on. Therefore, the number of files in the zip file may be greater than the number of files that the Support Workbench had previously displayed as the package contents.

The Incident Packaging Service follows a set of rules to determine the trace files in the ADR that are correlated to existing package data. You can modify some of those rules in the Incident Packaging Configuration page in Cloud Control.

Because both initial package data and added correlated data may contain sensitive information, it is important to have an opportunity to remove or edit files that contain this information before uploading to Oracle Support. For this reason, the Support Workbench enables you to run a command that finalizes the package as a separate operation. After manually finalizing a package, you can examine the package contents, remove or edit files, and then generate and upload a zip file.

Note:

Finalizing a package does not mean closing it to further modifications. You can continue to add diagnostic data to a finalized package. You can also finalize the same package multiple times. Each time that you finalize, any new correlated data is added.

9.10.1.3 About Quick Packaging and Custom Packaging

The Support Workbench provides two methods for creating and uploading an incident package: the quick packaging method and the custom packaging method.

Quick Packaging—This is the more automated method with a minimum of steps, organized in a guided workflow (a wizard). You select a single problem, provide a package name and description, and then schedule upload of the package contents, either immediately or at a specified date and time. The Support Workbench automatically places diagnostic data related to the problem into the package, finalizes the package, creates the zip file, and then uploads the file. With this method, you do not have the opportunity to add, edit, or remove package files or add other diagnostic data such as SQL test cases. However, it is the simplest and quickest way to get first-failure diagnostic data to Oracle Support. Quick packaging is the method used in the workflow described in "Investigating, Reporting, and Resolving a Problem".

When quick packaging is complete, the package that was created by the wizard remains. You can then modify the package with custom packaging operations at a later time and manually reupload.

Custom Packaging—This is the more manual method, with more steps. It is intended for expert Support Workbench users who want more control over the packaging process. With custom packaging, you can create a new package with one or more problems, or you can add one or more problems to an existing package. You can then perform a variety of operations on the new or updated package, including:

  • Adding or removing problems or incidents

  • Adding, editing, or removing trace files in the package

  • Adding or removing external files of any type

  • Adding other diagnostic data such as SQL test cases

  • Manually finalizing the package and then viewing package contents to determine if you must edit or remove sensitive data or remove files to reduce package size.

You might conduct these operations over several days, before deciding that you have enough diagnostic information to send to Oracle Support.

With custom packaging, you create the zip file and request the upload to Oracle Support as two separate steps. Each of these steps can be performed immediately or scheduled for a future date and time.

9.10.1.4 About Correlated Packages

Correlated packages provide a means of packaging and uploading diagnostic data for related problems.

A database instance problem can have related problems in other database instances or in Oracle Automatic Storage Management instances, as described in "Related Problems Across the Topology". After you create and upload a package for one or more database instance problems (the "main package"), you can create and upload one or more correlated packages, each with one or more related problems. You can accomplish this only with the custom packaging workflow in Support Workbench.

9.10.2 Packaging and Uploading Problems with Custom Packaging

You use Support Workbench (Support Workbench) to create and upload custom incident packages (packages). Before uploading, you can manually add, edit, and remove diagnostic data files from the package.

To package and upload problems with custom packaging:

  1. Access the Support Workbench home page.

    See "Viewing Problems with the Support Workbench" for instructions.

  2. (Optional) For each problem that you want to include in the package, indicate the service request number (SR#) associated with the problem, if any. To do so, complete the following steps for each problem:

    1. In the Problems subpage at the bottom of the Support Workbench home page, select the problem, and then click View.

      Note:

      If you do not see the desired problem in the list of problems, or if there are too many problems to scroll through, select a time period from the View list and click Go. You can then select the desired problem and click View.

      The Problem Details page appears.

    2. Next to the SR# label, click Edit, enter a service request number, and then click OK.

      The service request number is displayed on the Problem Details page.

    3. Return to the Support Workbench home page by clicking Support Workbench in the locator links at the top of the page.

      Description of problem_details_breadcrumb.gif follows

    The Select Packaging Mode page appears.

    Note:

    The packaging process may automatically select additional correlated problems to add to the package. An example of a correlated problem is one that occurs within a few minutes of the selected problem. See "About Correlated Diagnostic Data in Incident Packages" for more information.

  4. Select the Custom packaging option, and then click Continue.

    The Select Package page appears.

    Description of package_create_select.gif follows
    Description of the illustration package_create_select.gif

  5. Do one of the following:

    • To create a new package, select the Create new package option, enter a package name and description, and then click OK.

    • To add the selected problems to an existing package, select the Select from existing packages option, select the package to update, and then click OK.

    The Customize Package page appears. It displays the problems and incidents that are contained in the package, plus a selection of packaging tasks to choose from. You run these tasks against the new package or the updated existing package.

    Description of package_details.gif follows
    Description of the illustration package_details.gif

  6. (Optional) In the Packaging Tasks section, click links to perform one or more packaging tasks. Or, use other controls on the Customize Package page and its subpages to manipulate the package. Return to the Customize Package page when you are finished.

    See "Viewing and Modifying Incident Packages" for instructions for some of the most common packaging tasks.

  7. In the Packaging Tasks section of the Customize Package page, under the heading Send to Oracle Support, click Finish Contents Preparation to finalize the package.

    A list (or partial list) of files included in the package is displayed. (This may take a while.) The list includes files that were determined to contain correlated diagnostic information and added by the finalization process.

    See "About Correlated Diagnostic Data in Incident Packages" for a definition of package finalization.

  8. Click Files to view all the files in the package. Examine the list to see if there are any files that might contain sensitive data that you do not want to expose. If you find such files, then exclude (remove) or edit them.

    See "Editing Incident Package Files (Copying Out and In)" and "Removing Incident Package Files" for instructions for editing and removing files.

    To view the contents of a file, click the eyeglasses icon in the rightmost column in the table of files. Enter host credentials, if prompted.

    Note:

    Trace files are generally for Oracle internal use only.

  9. Click Generate Upload File.

    The Generate Upload File page appears.

  10. Select the Full or Incremental option to generate a full package zip file or an incremental package zip file.

    For a full package zip file, all the contents of the package (original contents and all correlated data) are always added to the zip file.

    For an incremental package zip file, only the diagnostic information that is new or modified since the last time that you created a zip file for the same package is added to the zip file. For example, if trace information was appended to a trace file since that file was last included in the generated physical file for a package, the trace file is added to the incremental package zip file. Conversely, if no changes were made to a trace file since it was last uploaded for a package, that trace file is not included in the incremental package zip file.

    Note:

    The Incremental option is dimmed (unavailable) if an upload file was never created for the package.

  11. Schedule file creation either immediately or at a future date and time (select Immediately or Later), and then click Submit.

    File creation can use significant system resources, so it may be advisable to schedule it for a period of low system usage.

    A Processing page appears, and creation of the zip file proceeds. A confirmation page appears when processing is complete.

    Note:

    The package is automatically finalized when the zip file is created.

  12. Click OK.

    The Customize Package page returns.

  13. Click Send to Oracle.

    The View/Send Upload Files page appears.

  14. (Optional) Click the Send Correlated Packages link to create correlated packages and send them to Oracle.

    See "Creating, Editing, and Uploading Correlated Packages". When you are finished working with correlated packages, return to the View/Send Upload Files page by clicking the Package Details link at the top of the page, clicking Customize Package, and then clicking Send to Oracle again.

  15. Select the zip files to upload, and then click Send to Oracle.

    The Send to Oracle page appears. The selected zip files are listed in a table.

  16. Fill in the requested My Oracle Support information. Next to Create new Service Request (SR), select Yes or No. If you select Yes, a draft service request is created for you. You must later log in to My Oracle Support and fill in the service request details. If you select No, enter an existing service request number.

  17. Schedule the upload to take place immediately or at a future date and time, and then click Submit.

    A Processing page appears. If the upload is completed successfully, a confirmation page appears. If the upload could not complete, an error page appears. The error page may include a message that requests that you upload the zip file to Oracle manually. If so, contact your Oracle Support representative for instructions.

  18. Click OK.

    The View/Send Upload Files page returns. Under the Time Sent column, check the status of the files that you attempted to upload.

    Note:

    The Support Workbench uses Oracle Configuration Manager to upload the physical files. If Oracle Configuration Manager is not installed or properly configured, the upload may fail. In this case, a message is displayed with a path to the package zip file and a request that you upload the file to Oracle Support manually. You can upload manually with My Oracle Support.

    For more information about Oracle Configuration Manager, see Oracle Configuration Manager Installation and Administration Guide.

  19. (Optional) Create and upload correlated packages.

    A list of files in the package is displayed.

    If you have not yet generated a physical file for this package, all package files are displayed in the list. If you have already generated a physical file, then a View list appears above the files list. It enables you to choose between viewing only incremental package contents or the full package contents. The default selection is incremental package contents. This default selection displays only those package files that were created or modified since the last time that a physical file was generated for the package. Select Full package contents from the View list to view all package files.

  3. Select the files to remove, and then click Exclude.

    Note:

    If you do not see the desired files, then they may be on another page. Click the Next link to view the next page. Continue clicking Next, or select from the list of file numbers (to the left of the Next link) until you see the desired files. You can then select the files and click Remove.

9.10.3.6 Viewing and Updating the Incident Package Activity Log

The Support Workbench maintains an activity log for each incident package.

Most activities that you perform on a package, such as adding or removing files or creating a package zip file, are recorded in the log. You can also add your own notes to the log. This is especially useful if multiple database administrators are working with packages.

To view and update the incident package activity log:

  1. Access the Package Details page for the desired incident package.

    See "Viewing Package Details" for instructions.

  2. Click the Activity Log link to view the Activity Log subpage.

    The activity log is displayed.

  3. To add your own comment to the activity log, enter text into the Comment field, and then click Add Comment.

    Your comment is appended to the list.

9.10.4 Creating, Editing, and Uploading Correlated Packages

After you upload a package to Oracle Support, you can create and upload one or more correlated packages.

This is recommended if critical alerts appeared in the Related Alerts section of the Database Home page. The correlated packages are associated with the original package, also known as the main package. The main package contains problems that occurred in a database instance. Correlated packages contain problems that occurred on other instances (Oracle ASM instances or other database instances) and that are related problems for the problems in the main package. There can be only one correlated package for each related instance.

To create, edit, and upload a correlated package:

  1. View the Package Details page for the main package.

    See "Viewing Package Details" for instructions.

  2. On the Package Details page, click Customize Package.

  3. On the Customize Package page, in the Packaging Tasks section, under Additional Diagnostic Data, click Create/Update Correlated Packages.

  4. On the Correlated Packages page, under Correlated Packages, select one or more instances that have incidents and click Create.

    A confirmation message appears, and the package IDs of the newly created correlated packages appear in the ID column.

  5. Select the instance on which you created the correlated package, and click Finish Contents Preparation.

    A confirmation message appears.

  6. (Optional) View and edit a correlated package by completing these steps:

    1. Click the package ID to view the package.

      If prompted for credentials, enter them and click Login.

    2. On the Package Details page, click Files to view the files in the package.

    3. Click Customize Package and perform any desired customization tasks, as described in "Viewing and Modifying Incident Packages".

  7. For each correlated package to upload, click Generate Upload File.

  8. For each correlated package to send to Oracle, select the package and click Send to Oracle.

    Note:

    If Send to Oracle is unavailable (dimmed), then there were no correlated incidents for the instance.

9.10.5 Deleting Correlated Packages

You delete a correlated package with the Support Workbench for the target for which you created the package.

For example, if you created a correlated package for an Oracle ASM instance target, access the Support Workbench for that Oracle ASM instance.

To delete a correlated package:

  1. Access the Support Workbench for the target on which you created the correlated package.

    Tip:

    See the Related Links section at the bottom of any Support Workbench page. Or, see "Viewing Problems with the Support Workbench"

  2. Click Packages to view the Packages subpage.
  3. Locate the correlated package in the list. Verify that it is a correlated package by viewing the package description.
  4. Select the package and click Delete.
  5. On the confirmation page, click Yes.

9.10.6 Setting Incident Packaging Preferences

You can set incident packaging preferences. Examples of incident packaging preferences include the number of days to retain incident information, and the number of leading and trailing incidents to include in a package for each problem.

By default, if a problem has many incidents, only the first three and last three incidents are packaged. You can change these and other incident packaging preferences with Cloud Control or with the ADRCI utility.

To set incident packaging preferences with Cloud Control:

  1. Access the Support Workbench home page.
  2. In the Related Links section at the bottom of the page, click Incident Packaging Configuration.

    The View Incident Packaging Configuration page appears. Click Help to view descriptions of the settings on this page.

  3. Click Edit.

    The Edit Incident Packaging Configuration page appears.

  4. Edit settings, and then click OK to apply changes.
