DBCS - Database Cloud Service Patching

Here in this article, I would summarize how easily we can do the "Database Cloud Service" patching online just via few clicks from the "Oracle Cloud Service Console".


Login to the Cloud Console and go to the DBCS instance page.

Click on the DBCS instance you want to patch, Instance Overview page opens. In my below example, there is a primary and standby Cloud instances.

At left side, click on the "Administration" tab, Patching page opens up which has list of all Available Patches for the underline DBCS instance.

Choose the right PSU Update and click on the right side hamburger sign, and click on Patch prechecks. Once you click on the pre-checks, it confirms if the patch is downloadable and /u01 mount on the DBCS instance host has enough free space available.

You can navigate through "Activity" tab to see the pre-check detail steps.

Once the pre-check completes, then initiates the actual patching job, it asks for the Patching Notes and choose whether you want to patch with "Switch-over" so there is no down-time.


The node hosting the standby database is patched first. A switchover operation is performed after patching is complete on the standby and then the patch is applied to the node hosting the new
standby.

If you want errors to be ignored during the patching operation, select the Force apply patch option. Then, click Patch.
