To perform post-upgrade tasks

1. Change the cluster configuration to read-write mode:

   # haconf -makerw

2. For upgrades from Oracle RAC 9i: Modify the resources in the Oracle service groups:

   # hares -modify db_resname StartUpOpt SRVCTLSTART 
   # hares -modify db_resname ShutDowmOpt SRVCTLSTOP
   # hares -modify db_resname pfile "" -sys node_name1 
   # hares -modify db_resname pfile "" -sys node_name2

3. Add the Oracle UDP IPC private IP addresses to the Oracle init.ora file if the database cache fusion traffic is configured to use Oracle UDP IPC private IP addresses and if these addresses are configured as a PrivNIC or MultiPrivNIC resource for high availability.
4. Modify the Oracle RAC configuration to prevent automatic startup of Oracle Clusterware.

   See Preventing automatic startup of Oracle Clusterware/Grid Infrastructure.

5. Modify the Oracle RAC database configuration to prevent automatic database startup if you want the Oracle RAC database to be managed by VCS using the Oracle agent.

   See Preventing automatic database startup.

6. Unfreeze the VCS service groups that were frozen earlier.

   As root user, enter:

   # hagrp -unfreeze oradb_grpname -persistent

   # hagrp -unfreeze cvm_grpname -persistent

   # haconf -dump -makero
