23 Patching Oracle Business Intelligence Systems 23-1 23 Patching Oracle Business Intelligence Systems Patching involves copying a small collection of files over an existing installation. A patch is normally associated with a particular version of an Oracle product and involves updating from one minor version of the product to a newer minor version of the same product for example, from version 11.1.1.2.0 to version 11.1.1.3.0. A patch set is a single patch that contains a collection of patches that are designed to be applied at the same time. For more information, see Oracle Fusion Middleware Patching Guide. This chapter includes the following topics: ■ Section 23.1, What Is Patched for the Oracle Business Intelligence Platform? ■ Section 23.2, Patching the Platform ■ Section 23.3, Rolling Back a Platform Patch ■ Section 23.4, Determining Current Patch Levels 23.1 What Is Patched for the Oracle Business Intelligence Platform? Oracle Business Intelligence platform patching applies patches for binary files with extensions such as DLL, JAR, and EXE. Oracle Business Intelligence platform patching does not patch the following: ■ Configuration Files If configuration updates are required as part of a patch, then these are detailed in the accompanying README.txt file, and you must manually apply them. No automated mechanism is available for merging customer configuration and patched configuration files. ■ Schema-based Metadata Nondesign-time metadata that is stored in database schemas including schemas for the Scheduler, usage statistics, event polling, repository files, and the Oracle BI Presentation Catalog is not patched. Other platform metadata such as repository files and Oracle BI Presentation Catalog files that are delivered in the context of an application are patched, but as part of an applications patch and not as part of a platform patch. 23-2 System Administrators Guide for Oracle Business Intelligence Enterprise Edition

23.2 Patching the Platform

Typically you apply a patch that contains one or more bug fixes to an existing production Oracle BI EE system that is distributed across one or more computers. Bug fixes might affect the system components and Java components that are deployed inside the Oracle WebLogic Server. The patch might include new server executables and updated and new Java class files. You use the Oracle OPatch utility to apply and to roll back Oracle BI EE platform patches. You download patches from Oracle Support Services, as described in Section 23.2.2, Applying a Patch to the Platform. For more information about patching in Oracle Fusion Middleware, see Oracle Fusion Middleware Patching Guide. This section contains the following topics: ■ Section 23.2.1, What Conditions Apply when Patching the Platform? ■ Section 23.2.2, Applying a Patch to the Platform ■ Section 23.2.3, What Happens If a Patching Conflict Occurs? 23.2.1 What Conditions Apply when Patching the Platform? The following conditions apply when patching the Oracle BI EE platform: ■ Oracle BI EE 11g Release 1 11.1.1 must be installed, and previous versions must have been upgraded to this 11g release. ■ Oracle Business Intelligence must be stopped before the patch is applied and restarted after all the components are successfully patched. ■ If a patch affects existing Java components or includes new Java components, then you must re-deploy the components after applying the patch.

23.2.2 Applying a Patch to the Platform

You must apply a patch to all the related Oracle homes for a given Oracle Business Intelligence system, distributed across multiple computers. Oracle BI EE components must be patched to the same version. You must check the patch version of each Oracle home, one at a time. For information, see Section 23.4, Determining Current Patch Levels. Complete the tasks that are described in the following sections to apply a patch: 1. Section 23.2.2.1, Step 1: Download the Patch 2. Section 23.2.2.2, Step 2: Stop System Component Processes for Oracle BI EE 3. Section 23.2.2.3, Step 3: Apply the Patch to Each Oracle Home 4. Section 23.2.2.4, Step 4: Start System Component Processes for Oracle BI EE 5. Section 23.2.2.5, Step 5: Redeploy Patched J2EE Applications
