Oracle Fusion Applications Patching Concepts


Oracle Fusion Applications Patching Concepts

Oracle Fusion Applications Patch Manager is the utility to apply the patches in Oracle Fusion Applications.

The primary function of Oracle Fusion Applications Patch Manager is to manage patches that update both the database and middleware artifacts under the Oracle Fusion Applications Oracle home.

Oracle Fusion Applications Patch Manager provides a command-line interface to coordinate its patching functions. A single patch may include changes to both Oracle Fusion Middleware and database artifacts, and these Oracle Fusion Middleware artifacts may be deployed to Managed Servers running on different nodes.

To patch both types of artifacts, two patching tools are called by Oracle Fusion Applications Patch Manager to manage the actions involved: OPatch for the Oracle Fusion Middleware artifacts and Oracle Fusion Applications AutoPatch for artifacts associated with the database.

Oracle Fusion Applications Patch Manager examines patch metadata and determines which actions must be performed by OPatch and which must be performed by Oracle Fusion Applications AutoPatch. If Oracle Fusion Applications Patch Manager discovers that a patch contains only database changes, it assigns the patch directly to Oracle Fusion Applications AutoPatch for processing. If the patch is related only to Oracle Fusion Middleware changes, Oracle Fusion Applications Patch Manager orchestrates the application of the changes across domains and the Oracle home. If the patch contains both database and Oracle Fusion Middleware changes, Oracle Fusion Applications Patch Manager coordinates the application of both changes, applying database changes first, followed by Oracle Fusion Middleware changes

What happens when you apply a Fusion Applications Patch

1. Oracle Fusion Applications Patch Manager interprets the contents of the patch by reading the patch metadata.

2. Oracle Fusion Applications AutoPatch updates the seed data.

3. OPatch applies the change to the Oracle ADF library in the form of a JAR file.

4. Oracle Fusion Applications Patch Manager coordinates with OPatch and forces an immediate shutdown and restart of the impacted Managed Servers so the change to the Oracle ADF library takes effect.

5. Oracle Fusion Applications Patch Manager consolidates and provides results and status for the overall patching tasks in the Log Summary and the Diagnostics report.
