Setting Up and Managing Disaster Recovery Sites 4-75
To use the original production site as the new production site, you perform the steps above again, but configure the rsync replications to go in the original direction from
the original production site to the original standby site.
4.6 Patching an Oracle Fusion Middleware Disaster Recovery Site
This section describes how to apply an 11g Oracle Fusion Middleware patch set to upgrade the Oracle homes that participate in an Oracle Fusion Middleware Disaster
Recovery site.
The list in this section describes the steps for applying a patch set to upgrade the 11g Oracle Fusion Middleware homes in an Oracle Fusion Middleware Disaster Recovery
production site.
The following steps assume that the Oracle Central Inventory for any Oracle Fusion Middleware instance that you are patching is located on the production site shared
storage, so that the Oracle Central Inventory for the patched instance can b e replicated to the standby site.
Use the following procedure to upgrade 11g Oracle Fusion Middleware patch versions:
1.
Perform a backup of the production site to ensure that the starting state is secured.
2.
Apply the patch set to upgrade the production site instances.
3.
After applying the patch set, manually force a synchronization of the production site shared storage and standby site shared storage. This replicates the production
site’s patched instance and Oracle Central Inventory in the standby site’s shared storage.
4.
After applying the patch set, use Oracle Data Guard to manually force a synchronization of the Oracle databases at the production site and standby sites.
Some Oracle Fusion Middleware patch sets may make updates to repositories, so this step ensures that any changes made to production site databases are
synchronized to the standby site databases.
5.
The upgrade is now complete. Your Disaster Recovery topology is ready to resume processing.
Note: Patches must be applied only at the production site for an 11g
Oracle Fusion Middleware Disaster Recovery topology. If a patch is for an Oracle Fusion Middleware instance or for the Oracle Central
Inventory, the patch will be copied when the production site shared storage is replicated to the standby site shared storage. A
synchronization operation should be performed when a patch is installed at the production site.
Similarly, if a patch is installed for a production site database, Oracle Data Guard will copy the patch to the standby database at the standby
site when a synchronization is performed.
