Decide how you want to patch Oracle Database Appliance. With Patch Set Bundle 12.1.2.7, you have two options.
You can patch Oracle Database Appliance using either automatic rolling patching, or manual rolling patching. Review the steps for each procedure, and decide which option you want to use. For each option, the steps are the same, except for the server patch (step 4).
For both options, the storage patch requires a system restart of Oracle Database Appliance after completing the storage patch update. However, you can defer the update to a maintenance window.
Note:
You must be on Patch Set Release 12.1.2.6 before you can upgrade to 12.1.2.7.
In 12.1.2.7, you must patch the server before you patch the storage. See My Oracle Support note 888888.1 for information about the latest Oracle Database Appliance patch bundle.
Automatic Rolling Patching Option
The advantage of automatic rolling patching is that it is simple to do, in that you start the patch, and the patch process completes automatically. However, services and clients may experience delays during node restarts.
Automatic rolling patching consists of the following steps:
Download the Oracle Database Appliance Patch Bundle from My Oracle Support.
Copy and unpack the patch bundle to both Oracle Database Appliance nodes.
Verify the components that require patching.
From node 0, start the patch. The automatic patch option performs the server patch update on Node 1, and restarts node 1. It then patches the server on Node 0, and restarts node 0.
(optional) Patch the shared storage components. This patch requires a system restart, but you can usually defer the restart.
Patch Oracle Databases. No restart is required.
Validate the Oracle Database and Oracle Grid Infrastructure patch installation.
Manual Rolling Patching Option
The advantage of manual rolling patching is that you can first migrate the services and clients from one node to another before the node restarts, and then manually patch the second node. This migration can be more graceful than a failover, so it can minimize interruptions to ongoing transactions.
Manual rolling patching consists of the following steps:
Download the Oracle Database Appliance Patch Bundle from My Oracle Support.
Copy and unpack the patch bundle to both Oracle Database Appliance nodes.
Verify the components that require patching.
Complete the patch manually in a two-step process.
Log in to Node 0, and patch the server on Node 0 by running the oakcli patch command using the --local option.
Wait until the patch operation completes, and Node 0 is available.
Log in to Node 1, and patch the server on Node 1 by running the oakcli patch command using the --local option.
(optional) Patch the shared storage. This patch requires a system restart, but you can usually defer the restart.
Patch Oracle Databases. No restart is required.
