Upgrading CRS from 10.2.0.1 to 10.2.0.3 (Patchset # 5337014 )

1. Stop the Oracle Cluster Services using the following command through root user in both the nodes,
$CRS_HOME/bin/crsctl stop resources
Crsctl query crs softwareversion
Crsctl quesr crs activeversion

2. Ensure no CRS services are running

3. Run the patch set 5337014 through as Oracle user (/Clusterware/Disk1/runInsaller)

4. Select the home as CRSHome and it’ll automatically set the path to (/CRS/app/10.2.0), where the CRS is installed in both the nodes

5. Click next, this window will show about the cluster configuration information and shows the nodes where this patcchset is going to be installed.

6. Click next, this will show the summary of the components that are going to be installed

7. Once the installation is over, we need to run the script root.sh as root user, once it’s done the CRS will be started automatically

8. Check it using the following command,
ps –ef grep CRS or $ ps –ef grep –I crs or $CRS_HOME/bin/crsctl check crs

9. Check the version using the following command,
$CRS_HOME/bin/crsctl query crs softwareversion
$CRS_HOME/bin/crsctl quesr crs activeversion

10. Stop the CRS,
$CRS_HOME/bin/crsctl stop resources

11. Run the shell script located at $CRS_HOME/install/root102.sh at each node

12. Edit /etc/init.d/init.crs to make the following changes in both the nodes,
chown oracle:dba /dev/raw/raw1
chown root:dba /dev/raw/raw3
chmod 644 /dev/raw/*
