Patching Oracle Grid Infrastructure Using Local-Mode Configuration

When you install Oracle Grid Infrastructure or when you upgrade an older version to this current version, the Fleet Patching and Provisioning Server is configured automatically in local mode.

Note:

Fleet Patching and Provisioning Server 21c is started automatically when patching command is invoked and the dependent resources are set up during the automatic startup process.

To switch the Fleet Patching and Provisioning Server from local mode to the regular, central mode (to manage remote targets), you must delete the current Fleet Patching and Provisioning Server in local mode, as follows:

$ srvctl stop rhpserver
$ srvctl remove rhpserver

Proceed with the steps described in "Creating a Fleet Patching and Provisioning Server" to create the central-mode Fleet Patching and Provisioning Server.

• The independent automaton for patching Oracle Grid Infrastructure performs all of the steps necessary to switch from one home to another. Because the automaton is not aware of gold images, moving the database requires two home paths, as follows:

  $ rhpctl move gihome -desthome destination_oracle_home_path –sourcehome Oracle_home_path 

Use the following rhpctl move gihome command parameters for the patching operation:

• -node: If the home you are moving is an Oracle Grid Infrastructure home installed on more than one node, then the default operation is a rolling update on all nodes. To apply a patch to just one node, specify the name of that node with this parameter.

• -nonrolling: If the home you are moving is an Oracle Grid Infrastructure home installed on more than one node, then the default operation is a rolling update on all nodes. To patch all nodes in a nonrolling manner, use this parameter instead of the -node parameter.

• -ignorewcpatches: By default, Fleet Patching and Provisioning will not perform the move operation if the destination home is missing any patches present in the source home. You can override this functionality by using this parameter, for example, to move back to a previous source home if you must undo an update.
