The below example is a screen output from installing CRS patchset 10.2.0.2

------------------------------------------------------------------------------------

The installer has detected that your Cluster Ready Services (CRS) installation is distributed across the following nodes:

mars
venus

Because the software consists of local identical copies distributed across each of the nodes in the cluster, it is possible to patch your CRS installation in a rolling manner, one node at a time.

To complete the installation of this patchset, you must perform the following tasks on each node:

1. Log in as the root user.
2. As the root user, perform the following tasks:

a. Shutdown the CRS daemons by issuing the following command:
/home10g/10.2/crs/bin/crsctl stop crs
b. Run the shell script located at:
/home10g/10.2/crs/install/root102.sh
This script will automatically start the CRS daemons on the
patched node upon completion.

3. After completing this procedure, proceed to the next node and repeat.

------------------------------------------------------------------------------------

Perform the root102.sh on all nodes one after each other and so a rolling CRS upgrade will be done.

After a successful upgrade on all nodes the softwareversion and activeversion should be like below:

# ./crsctl query crs softwareversion
CRS software version on node [mars] is [10.2.0.2.0]
# ./crsctl query crs activeversion
CRS active version on the cluster is [10.2.0.2.0]
