Complete the following steps when you apply patches to your Sun Cluster Geographic Edition system.
Shut down the Sun Cluster Geographic Edition infrastructure by using the geoadm stop command.
Shutting down the infrastructure ensures that a patch installation on one cluster does not affect the other cluster in the partnership.
Apply the patches by using the patchadd command.
If you are applying Sun Cluster patches, use the Sun Cluster methods on both clusters.
Apply patches to the secondary cluster first to ensure that errors do not affect the services on the primary cluster. After you have verified the installation, apply the patches to the primary cluster.
Restart the Sun Cluster Geographic Edition infrastructure by using the geoadm start command.
