Step 1 |
Selecting the Usecase Decide whether you want to upgrade single instance database, Oracle RAC database, or Oracle database clusterware, and then select the type of upgrade you want to perform on them. Oracle Database You can upgrade multiple database instances at a time using deployment procedure according the following usecases. :
You can even upgrade one database instance at a time. For example, if you have already upgraded some of the databases in the Oracle home earlier, and you now want to upgrade the other databases in the same Oracle home. |
To upgrade databases using deployment procedure, see Section 18.3. To upgrade one single instance database or one Oracle RAC database instance, see Section 18.4. |
|
Step 2 |
Knowing About the Supported Releases Know what releases of Oracle Database can be upgraded by the Deployment Procedure. |
To learn about the releases supported by the Deployment Procedure, see Section 18.2. |
|
Step 3 |
Understanding the Deployment Procedure Understand the Deployment Procedure you need to select, and its scope and coverage. |
To learn about the Deployment Procedure offered for upgrading databases, see Section 18.3.1. |
|
Step 4 |
Meeting the Prerequisites Before you run any Deployment Procedure, you must meet the prerequisites, such as setting up of the provisioning environment, applying mandatory patches, and setting up of Oracle Software Library. |

Upgrading Oracle Cluster Database Using Deployment Procedure
Upgrading Oracle Database Instance Using Deployment Procedure
Upgrading to Oracle Database 11g Release 2 or Oracle Database 12c enables you to access the latest technology, thereby increasing efficiency and providing secure data management for your applications. Ensure that you follow these steps to plan, prepare, and upgrade to make the upgrade process simpler, faster, and more predictable from start to finish.
Use the Upgrade Database deployment procedure to perform a mass upgrade of databases or when you want to install Oracle Home and upgrade database.
For mass upgrade of databases, source databases must be homogeneous, that is, they must have the same platform and same versions. The gold image to be used for the new database version must contain all patches required for these databases, effectively helping the user to get to a single standard gold image for the new release.
Cloud Control offers the Upgrade Oracle Database deployment procedure for mass upgrade of Oracle databases. The deployment procedure supports the following usecases:
Upgrading Database Instance Only
Upgrading Database Real Application Clusters
Upgrade of Clusterware
Note:
"Upgrading Grid infrastructure automatically upgrades the underlying ASM targets.For upgrading one Oracle database instance at a time or any Oracle RAC database instance, you must access the Oracle Database Upgrade wizard from the Home page of the database that you want to upgrade.
Note:
The Upgrade Database deployment procedure does not support upgrade of databases in Oracle Data Guard configurations and databases with Oracle Database Vault.The Deployment Procedure can be run by two types of administrators, mainly Designer and Operator. As a designer, you can set up a test database, deploy new software and patches, and test the upgrade process, and then create a gold image out of it. You can then access the Deployment Procedure, provide the required details, and lock one or more of the fields, such as platform, version, move to, and so on. Finally, you can save the procedure and then publish it to the operators.
As an operator, you can access the save procedure and perform only certain operations such as selecting a set of databases based on the locked criteria, providing any additional input that is specific to the runtime activity, and then scheduling the procedure. This way, the operators run a fully tested and certified Deployment Procedure in their production environments, and the entire operation tneds to be less error prone.
For more information on these types of administrators, and to learn how you can use these locking feature, see Section 2.4.
Before you upgrade an Oracle database, follow these prerequisites:
The following table lists the mininum source version and destination version required for each database target type:

This section describes how you can use the wizard to upgrade one single instance database or one Oracle RAC database instance at a time.
Upgrading enables you to access the latest technology, thereby increasing efficiency and providing secure data management for your applications. Ensure that you follow these steps to plan, prepare, and upgrade to make the upgrade process simpler, faster, and more predictable from start to finish.
The Database Upgrade feature allows you to submit a database upgrade job remotely from Enterprise Manager or schedule it for later execution.
Use this wizard to upgrade a standalone database where the Oracle Home has been installed or upgraded. For database upgrade automation or when Oracle Homes are not installed or upgraded, use the Upgrade Database deployment procedure explained in Upgrading Oracle Databases Using Deployment Procedures.
Note:
Since mass upgrade of Oracle RAC database is not supported at the moment, Oracle recommends that you use the wizard described in this section to upgrade one Oracle RAC database instance at a time.This section covers the following:
Before you upgrade an Oracle Database Instance, follow these prerequisites:
The database version must be 10.2.0.4 or above for upgrade to 11g or 12c.
For Oracle Real Application Clusters databases, if you select an Oracle RAC database instance and start the database upgrade process, it will upgrade the entire cluster database.
If OS authentication is not turned on, SYSDBA credentials are required for the upgrade.
Database to be upgraded must be up and running.
Ensure that you have DBA privileges to run this procedure.
To upgrade an Oracle Database Instance, follow these steps:
From the Enterprise menu, select Targets, then select Database. In the Databases page, select the source database to be upgraded.
In the Database Instance home page, from the Oracle Database menu, select Provisioning, then select Upgrade Database.
Note:
For single instance database instances, you will see another menu option to upgrade the Oracle home and the instance. If you select that option, you will be taken to the wizard described in Section 18.4, however, only the database instance, from where you navigated to the wizard, will be pre-selected for upgraded.Specify the Database user and password credentials and click Continue. The Database Upgrade wizard is launched.
In the Oracle Home page, select the New Oracle Home where you want the new Oracle Home for the upgrade to be installed, based on the version of the database to be upgraded.
If the Oracle Home is not a discovered target in Cloud Control, either discover the Oracle Home using the Cloud Control Discovery feature and then initiate the upgrade process or type the path of the Oracle Home manually. For Oracle Real Application Clusters databases, specify the Oracle RAC home.
For information about discovering targets in Cloud Control, see Chapter 3.
When specifying the new Oracle Home, you must have DBA permissions on both the source and destination Oracle Homes and these Oracle Homes must reside on the same host.
In the Oracle Home Credentials section, specify the host credentials. Host credentials must have DBA privileges and can be Preferred Credentials, or Named Credentials, or, you can select Enter Credentials and specify the user name and password and save it. Click More Details to view details about the host credentials you have selected. The specified Oracle Home credentials should have privileges on both the source database Oracle Home and the new Oracle Home. Click Test to verify that the credentials have the required privileges. If you are using Named Credentials, ensure that these are user and password credentials, else they will not be supported in Cloud Control.
Click Next. The errors and warnings from the prerequisite checks are displayed. Fix all errors and warnings and revalidate. Click OK to proceed to next step.
In the Options page, the Diagnostics destination field is displayed only for database upgrade from version 10.2.x to 11.1.0.6. The diagnostic destination is defaulted to Oracle Base and all diagnostic and trace files are stored at this location.
If you are upgrading from version 11.1.0.7 or higher to 11.2.x, the diagnostic destination field does not appear.
The Upgrade parallelism is set at a default value of 4. The maximum value is 8. This feature is available only when you are upgrading the database to 12c.
If archive logging has been turned on for the database, then you have the option to disable or Keep archive logging enabled during upgrade.
If flash recovery area has been configured for the database, then the Flash Recovery section will be displayed. Specify Flash Recovery Area Location and provide an adequate space for Size.
If you are upgrading to database version 11.2.0.2 or higher, you will be able to set the time zone upgrade option. You can select to Upgrade Time Zone Version and Timestamp with Time Zone data.
You can select Gather statistics if you want to gather optimizer statistics on fixed tables. This helps the optimizer to generate good execution plans. It is recommended that you gather fixed object statistics before you upgrade the database.
You can also select Make user tablespaces readonly. This makes the tablespaces read-only during the database upgrade, and it reverts back to read-write once the upgrade is done.
Note:
The Gather statistics and Make user tablespaces readonly options are available only when upgrading to 12c.Note:
If the database has ASM configured with it, the Backup section will not be displayed.In the Backup section, you can select:
Restore Settings Only to restore configuration changes made during database upgrade and not actual data, in case upgrade fails.
Perform full backup before upgrade and restore upon failure to restore oratab configuration. Specify a file system location for Backup Location. The credentials that you have specified earlier must have read-write permissions to this location.
Note:
If you perform a backup using RMAN then you can restore the entire database irrespective of datafiles on filesystem or ASM. Backup using RMAN is available when upgrading to 12c only.Use an existing RMAN backup to restore database enables you to restore a database using the latest RMAN backup. This option is specific to upgrading a database to 12c.
Use guaranteed restore point to flashback the database.
Note:
The source database version should be from 11g onwards. The target home version should be 12cNone if you do not want to specify a database backup.
Note:
Starting with Oracle Database 12c Release 1 (12.1), Oracle Database supports the use of Oracle Home User, specified at the time of Oracle Database installation. This Oracle Home user is the owner of Oracle services that run from Oracle home and cannot be changed post installation. Different Oracle homes on a system can share the same Oracle Home User or use different Oracle Home User names.An Oracle Home User is different from an Oracle Installation User. An Oracle Installation User is the user who needs administrative privileges to install Oracle products. An Oracle Home User is a low-privileged Windows User Account specified during installation that runs most of the Windows services required by Oracle for the Oracle home. For more information about Oracle Home User, see Oracle Database Platform Guide..
For database version 12.1 or higher, for Microsoft Windows operating systems, the database services will be configured for the Microsoft Windows user specified during Oracle home installation.This user will own all services run by Oracle software.
In the Oracle Home Windows User Credentials section, specify the host credentials for the Microsoft Windows user account to configure database services. Select existing named credentials or specify new credentials. To specify new credentials, provide the user name and password. You can also save these credentials and set them as preferred credentials.
In the Advanced section, specify the custom SQL scripts you want to run before and after the database upgrade. Copy these scripts to the host file system and select them. If your custom scripts are stored as a component in the Software Library, select Select these scripts from the Software Library and then browse the Software Library for these scripts. During execution, the main file specified in the Software Library component will be run. So, if you want to run a set of scripts, organize them in the main script file and specify the main script in the Software Library component.
Select Recompile invalid objects at the end of upgrade to make valid database objects for the new database version. Setting a higher Degree of Parallelism will ensure faster recompilation of objects. The default setting is the number of CPU count of the host.
Click Next.
The Listeners page is displayed only for single instance database upgrade. In the Listeners page, listeners that are registered with Oracle Restart and those that are running in the new Oracle Home are displayed. You can create a new listener or migrate your existing listener manually and then upgrade the database. If you create a new listener, the listener will then be an Cloud Control target and will be monitored. If you migrate your existing listener, the upgrade job will register the database with the listener.
If you have listeners running in the source Oracle Home and need to maintain the same listener port after upgrade, migrate your listener manually to the new Oracle Home first.
For Oracle Real Application Clusters database, the upgraded database will be registered with the Clusterware listener automatically and the Listeners page will not appear.
To add a new listener, specify the Name and Port Number.
Click Next.
In the Schedule page, edit or retain the Job Name and Description for the database upgrade. If you want to run the job immediately, then retain the default selection, that is, Immediately. If you want to run the job later, then select Later and provide time zone, start date, and start time details. Specify a Grace Period, a duration after the start period for Cloud Control to attempt to start the upgrade job if it cannot start at the specified time.
Select Blackout the database target in Enterprise Manager during upgrade if you do not want the database to be monitored and alerts to be raised by Cloud Control during the upgrade.
Click Next.
In the Review page, ensure that you review all warnings generated in the Validation Summary. Click the Validation Summary icon to view validation results and severity and action taken for any warnings. Verify that the details you have provided for the upgrade job appear correctly and then click Submit Job to run the job according to the schedule set. If you want to modify the details, then click Back repeatedly to reach the page where you want to make the changes. Click Save to save the deployment procedure for future deployment.
After you have submitted the job, the Database Upgrade Job page with the summary for the running job will be displayed. In the Jobs page, view the job summary and the list of steps and view their status.
Note:
If the database upgrade fails for any reason and you have not specified a backup option in the Database Upgrade wizard, restore the database manually and perform the upgrade again. If the database upgrade succeeded, but post upgrade custom scripts did not run, then the database will not be restored since upgrade has succeeded.After the upgrade job is completed successfully, click on the Targets menu and select All Targets to navigate to the All Targets page and verify that the newly upgraded database is displayed as an Cloud Control target with the correct database version.
