Upgrading to Oracle Grid Infrastructure 21c

This procedure uses Fleet Patching and Provisioning to upgrade your Oracle Grid Infrastructure cluster from 19c to 21c.

Before You Begin

To upgrade to Oracle Grid Infrastructure 21c, your source must be Oracle Grid Infrastructure 12c release 2 (12.2.0.1), Oracle Grid Infrastructure 18c, or Oracle Grid Infrastructure 19c.

Ensure that groups configured in the source home match those in the destination home.

Ensure that you have an image GI_HOME_21c of the Oracle Grid Infrastructure 21c software to provision your working copy.

GI_19c is the active Grid Infrastructure home on the cluster being upgraded. It is a working copy because in this example, Fleet Patching and Provisioning provisioned the cluster. Fleet Patching and Provisioning can also upgrade clusters whose Grid Infrastructure homes are unmanaged that is, homes that Fleet Patching and Provisioning did not provision.

Procedure

1. Provision a working copy of the Oracle Grid Infrastructure 21c software:

   $ rhpctl add workingcopy -workingcopy GI21c -image GI_HOME_21c {authentication_option}

   GI21c is the working copy based on the image GI_HOME_21c.

2. Upgrade your target cluster to the GI21c working copy:

   rhpctl upgrade gihome -sourcewc GI19c -destwc GI21c

   Rapid Home Provisioning identifies the cluster to upgrade based on the name of the source working copy, and upgrades to the working copy GI21c.
