This chapter describes configuring log files for diagnosing issues in BI Publisher and configuring user auditing to capture metrics on user activity and system performance.
It covers the following topics:
System administrators are typically responsible for supporting end users when they experience issues with the use of Oracle BI Publisher and for interacting with Oracle Support to understand the cause of issues and apply fixes.
Issues may be reported in response to end users receiving error messages, experiencing poor performance, or lack of availability.
The principal activities administrators perform to support issue resolution include:
Examination of error and diagnostic log information. For more information, see:
Examination of system and process metrics to understand availability and performance issues. For more information, see:
BI Publisher writes diagnostic log files in the Oracle Diagnostic Logging (ODL) format. Log file naming and the format of the contents of log files conforms to an Oracle standard. You can view log files by using the WLST displayLogs command, or you can download log files to your local client and view them using another tool (for example a text editor, or another file viewing utility).
Log files are created and edited using Oracle Fusion Middleware Control. By default, after installation, the bipublisher-handler log is created. You can configure this log file or create a new logger.
Each log file message category is set to a specific default value between 1-32, and only messages with a level less or equal to the log level are logged. Various log file message categories exist, as described in Table 13-1.
Table 13-1 Log File Message Category Levels
A serious problem caused by unknown reasons. You can only fix the problem by contacting Oracle support. Examples are errors from which you cannot recover or serious problems.
A problem requiring attention from the system administrator has occurred, and is not caused by a bug in the product. No performance impact.
A potential problem that should be reviewed by the administrator. Examples are invalid parameter values or a specified file does not exist.
A major lifecycle event such as the activation or deactivation of a primary sub-component or feature. This is the default level for NOTIFICATION.
A finer level of granularity for reporting normal events.
Trace or debug information for events that are meaningful to administrators, such as public API entry or exit points.
Detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem.
Very detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem.
A log file must contain a consistent format. However, since there can be multiple formats, you can change the format used in a log file. When you change the format used in a log file, and the new format differs from the current log file's format, a new log file is created. For example, a log file that contains ODL-XML, always contains XML, and is never mixed with text.
Configure the log file format in the Edit Log File dialog. See Section 13.3, "Configuring Log Files." The format can by Text or XML.
This section describes using Oracle Fusion Middleware Control to configure BI Publisher log files. It includes the following topics:
To set the log level in Oracle Fusion Middleware Control:
In Oracle Fusion Middleware Control, locate the BI Publisher server. For example:
Under Application Deployments, expand bipublisher (11.1.1.) (bi_cluster), and then right-click bipublisher (11.1.1)(bi_server1)
From the menu, click Logs and then Log Configuration as shown in Figure 13-1:

The log file is located in the directory that is specified in the Log Path in the Edit Log File dialog. Navigate to the directory on the server to view the log file.
The following example shows an ODL format error message:
<msg time="2009-07-30T16:00:03.150-07:00" comp_id="xdo" type="ERROR" level="1" host_id="MyBIPHost" host_addr="126.96.36.199" module="oracle.xdo" tid="11" user="Administrator"> <txt>Variable 'G_dept' is missing...</txt> </msg>
Table 13-2 describes the message attributes displayed in the log file:
Table 13-2 Log File Message Attributes
The date and time when the message was generated. This reflects the local time zone.
The ID of the component that originated the message.
The type of message. Possible values are: INCIDENT_ERROR, ERROR, WARNING, NOTIFICATION, TRACE, and UNKNOWN. See Table 13-1 for information about the message types.
The message level, represented by an integer value that qualifies the message type. Possible values are from 1 (highest severity) through 32 (lowest severity).
The name of the host where the message originated.
The network address of the host where the message originated.
The ID of the module that originated the message. If the component is a single module, the component ID is listed for this attribute.
The ID of the thread that generated the message.
The name of the user whose execution context generated the message.
Performance monitoring enables you to monitor the performance of queries, reports and document generation and to analyze the provided details.
BI Publisher collects performance statistics through JMX Management Beans or Mbeans. Each MBean reveals attributes, operations, and relevant statistics gathered by the Oracle Dynamic Monitoring Service (DMS). Table 13-3 summarizes the beans that are provided.
Table 13-3 Management Beans
Creates an Mbean per report and displays detailed monitoring data for the report.
Exists per server and displays user and server activity summaries.
Creates an Mbean per user and displays detailed monitoring data for the user.
To enable monitoring, complete the following tasks:
Enable Monitor and Audit on the Administration Server Configuration page. See Section 13.6.1, "Enable Monitor and Audit on the Server Configuration Page."
Configure the Audit Policy Settings with Fusion Middleware Control (Enterprise Manager). See Section 13.6.2, "Configure the Audit Policy Settings."
(Optional) For non-English installations of Oracle Fusion Middleware Control that require a translated user interface, copy the translation files to the appropriate location. See Section 13.6.3, "(Optional) Copy Translation Files."
Restart WebLogic Server.
To turn on monitoring and auditing for the BI Publisher application:
Click the Administration link.
Under System Maintenance, click Server Configuration.
Under the Monitor and Audit region, select the Enable Monitor and Audit check box.
To configure the audit policy settings:
In Oracle Fusion Middleware Control, under WebLogic Domain, right-click bifoundation_domain. From the menu, click Security and click Audit Policy, as shown in Figure 13-8.
Figure 13-8 Navigating to the Audit Policy Settings
The Audit Policy page displays the audited applications under the bifoundation_domain. From the Audit Component Name list, select BI Publisher Server. Set the Audit Level to enable auditing for BI Publisher. An example is shown in Figure 13-9.
Figure 13-9 Audit Policy Page
Typically set the Audit Level to Medium.
To customize the audit level for each event, select Custom from the Audit Level list. This setting enables you to set the audit level for each event and apply filters. Select a category (UserSession, ReportAccess, or ReportExecution) to view the available events.
The events that are audited for the BI Publisher server are:
Scheduled Report Request
Report Data Download
Report Data Process
If you require that your Oracle Fusion Middleware Control (Enterprise Manager) user interface displays in a non-English language, you must copy the BI Publisher translation files from the BI Publisher repository to the appropriate location in the Oracle BI Enterprise Edition installation directory for the BI Publisher audit event user interface components to display in the correct language when viewed in Enterprise Manager.
Navigate to the Audit directory located under the BI Publisher repository: <BI Publisher deployment directory>/repository/Admin/Audit
Copy the *.xlf files from the Audit directory to the Oracle BI Enterprise Edition installation directory located: /oracle_common/modules/oracle.iau_11.1.1/components/xmlpserver
If you set the property AUDIT_JPS_INTEGRATION to true, then the audit log can be viewed under the xmlpserver folder under the WebLogic Server AdminServer directory: /AdminServer/logs/auditlogs/xmlpserver/audit.log
Alternatively, you can configure an audit repository in the database to store audit data in database tables instead of the log file (the file is not generated in this case). The collected data can be analyzed using reports provided by Audit Framework, or you can create your own reports using BI Publisher.
For more information on the reports provided by Audit Framework, see "Using Audit Analysis and Reporting" in Oracle Fusion Middleware Application Security Guide.
The following section describes how to set up the audit repository in your database to store the auditing data.
Perform this procedure to configure an audit repository to store your auditing data collected by the Fusion Middleware Auditing Framework in database tables rather than a log file.
To set up the audit database in WebLogic Server:
Create the audit schema using RCU.
Create a data source in your WebLogic server.
Register the audit database to your domain.
To create the audit schema:
Go to $RCU_HOME/bin and execute the rcu command.
Choose Create at the starting screen and click Next.
Enter your database details and click Next.
Choose the option to create a prefix, and enter a prefix; for example: BIP
Select Audit Services from the list of schemas (shown in Figure 13-10).
Figure 13-10 List of Schemas
Click Next and accept the tablespace creation.
Click Finish to start the process.
When the Repository Creation Utility process finishes, the following audit-related schemas are created in your database:
<prefix>_IAU (for example:. BIP_IAU)
<prefix>_IAU_APPEND (for example: BIP_IAU_APPEND)
<prefix>_IAU_VIEWER (for example:. BIP_IAU_VIEWER)
After you create a database schema for your auditing data, next create a JDBC connection on your WebLogic Server so the Audit Framework can access the database schema that was created with the RCU in the previous step.
To create the JDBC connection:
Connect to the Oracle WebLogic Server administration console: http://hostname:port/console (e.g. http://example.com:7001/console)
Under Services, click the Data Sources link, as shown in Figure 13-11:
Figure 13-11 Navigating to the Data Sources Link
Click Lock and Edit.
On the Summary of JDBC Data Sources page, click New and then click Generic Data Source.
Enter the following details for the new data source:
Example: Audit Data Source-0
Figure 13-12 shows the example entries:
Figure 13-12 Create JDBC Data Source
Click Next and select the database driver. Choose "Oracle's Driver (Thin XA) Versions: 9.0.1 or later" if you are using Oracle database, and click Next.
In the Connections Properties page, enter the following:
Database Name: Enter the name of the database (SID) to which to connect.
Host Name: Enter the hostname of the database.
Port: Enter the database port.
Database User Name: Enter the name of the audit schema that you created in RCU. The suffix is always _IAU for the audit schema. For example, if you supplied the prefix as "BIP"', then the schema name would be "BIP_IAU".
Password: Enter the password for the audit schema that you created in RCU.
Figure 13-13 shows the Connection Properties page:
Figure 13-13 Connection Properties Page
Click Next. Accept the defaults, and click Test Configuration to verify the connection.
Click Next. Select the listed servers where you want to make this JDBC connection available.
Click Finish and then click Activate Changes in the Change Center.
To register the JNDI/JDBC data source as your auditing data storage with Fusion Middleware Control (Enterprise Manager):
Log in to Fusion Middleware Control.
Navigate to the WebLogic Domain, right click bifoundation_domain, then select Security, then Security Provider Configuration. The navigation path is shown in Figure 13-14.
Figure 13-14 Navigating to the Audit Store
On the Security Provider Configuration page, under Audit Service, click Configure.
On the Audit Service Configuration page, locate your Data Source JNDI Name by clicking Search datasource, as shown Figure 13-15.
From the Select Data Source dialog, select the data source you created and click OK.
Click Apply to continue.
Restart WebLogic Server.
When the WebLogic Server is restarted, BI Publisher stores all auditing data in the database table called "IAU_BASE". To verify this procedure, try logging in to BI Publisher and opening a few reports. You should see the activity audited in the "IAU_BASE" table. If not, check the log file for possible errors. The log file is located under the Oracle BI Domain Home, for example:
Once the data is successfully loading to the database tables, you can design your own auditing reports using BI Publisher.
Once you have the auditing repository set up, you can use BI Publisher to create your own reports to visualize your auditing data. To create a report on your auditing data in BI Publisher:
Register the data source in BI Publisher.
Create a data model.
Create the report.
Register the audit data source (JNDI/JDBC connection) that you created in the previous procedure as a JNDI data source in BI Publisher. Because you created a JDBC connection registered as JNDI, you do not need to create a new JDBC connection by typing the connection URL, username/password, and so on. You can just register it using the JNDI name (for example: jdbc/AuditDB).
Log in to BI Publisher with administrator privileges and click the Administration link.
Under Data Sources, click JNDI Connection, then click Add Data Source.
Enter the Data Source Name and JNDI Name. The JNDI Name is the name you provided in the WebLogic Console as the auditing data source (for example: jdbc/AuditDB).
Click Test Connection to ensure that the data source connection works.
Add the appropriate roles to the data source so that the report developers and consumers can view the reports built on this data source.
Click Apply to save.
To create a data model from your auditing data source:
Note: For the complete guidelines for developing data models in BI Publisher, see the Oracle Fusion Middleware Data Modeling Guide for Oracle Business Intelligence Publisher.
On the global header, click New and then click Data Model.
Set the Default Data Source to the audit JNDI data source.
Click Data Sets and from the Create New menu select new SQL Query data set.
Use the Query Builder to build a query or just type a SQL query against the IAU_BASE table. The IAU_BASE table contains all the auditing data for other products running on the WebLogic Server such as JPS, OID, and so on. To create a data model that contains only the BI Publisher data, then you can filter the data based on the value of the IAU_COMPONENTTYPE column that contains the product name. For BI Publisher, the value is "xmlpserver".
The following sample SQL query returns only BI Publisher data:
select "IAU_BASE"."IAU_COMPONENTTYPE" as "IAU_COMPONENTTYPE", "IAU_BASE"."IAU_EVENTTYPE" as "IAU_EVENTTYPE", "IAU_BASE"."IAU_EVENTCATEGORY" as "IAU_EVENTCATEGORY", "IAU_BASE"."IAU_TSTZORIGINATING" as "IAU_TSTZORIGINATING", to_char("IAU_TSTZORIGINATING", 'YYYY-MM-DD') IAU_DATE, to_char("IAU_TSTZORIGINATING", 'DAY') as IAU_DAY, to_char("IAU_TSTZORIGINATING", 'HH24') as IAU_HH24, to_char("IAU_TSTZORIGINATING", 'WW') as IAU_WEEK_OF_YEAR, "IAU_BASE"."IAU_INITIATOR" as "IAU_INITIATOR", "IAU_BASE"."IAU_RESOURCE" as "IAU_RESOURCE", "IAU_BASE"."IAU_TARGET" as "IAU_TARGET", "IAU_BASE"."IAU_MESSAGETEXT" as "IAU_MESSAGETEXT", "IAU_BASE"."IAU_FAILURECODE" as "IAU_FAILURECODE", "IAU_BASE"."IAU_REMOTEIP" as "IAU_REMOTEIP" from "BIP_IAU"."IAU_BASE" "IAU_BASE" where "IAU_BASE"."IAU_COMPONENTTYPE" = 'xmlpserver'
To test your data model, click Get XML Output. Select a sample size, and run your data model. Save the sample XML to your data model.
Save your data model.
Now you can use one of the BI Publisher's layout options to design the report layout and visualize the auditing data. To create a report using the BI Publisher layout editor:
On the global header, click New and then click Report.
Select the data model you created in the previous procedure.
To use the layout editor, click Add New Layout, and then click one of the Basic Templates to get started.
For complete instructions on using the layout editor, see the topic: "Creating BI Publisher Layout Templates" in the Help or in the Oracle Fusion Middleware Report Designer's Guide for Oracle Business Intelligence Publisher.
Figure 13-16 shows using the layout editor to design a report based on the auditing data:
Figure 13-16 Using the Layout Editor to Create an Auditing Report
Figure 13-17 shows a sample completed auditing report displayed in the report viewer:
