I'm getting ready to upgrade our current cluster
from 10.2.0.4 to 10.2.0.5 (Solaris 64-bit).
The components being upgraded include
clusterware, RAC, ASM, RDBMS, and Dataguard.
In regard to the clusterware, we have a 2 node cluster.
In the patch notes, it states that all Oracle database instances
on all cluster nodes, must be shut down before applying the
clusterware patch. Later on in the notes, it states that a
rolling upgrade for the clusterware can be done. I'm seeing
conflcting messages here.
I've done rolling upgrades before with patch sets, but not with an upgrade.
I've contacted Oracle support about this,but they were of little help.
Can the clusterware upgrade be done in a rolling fashion ?
In regard to Dataguard. We have physical standby, 2 - node cluster.
From what I understand, the physical standby should be upgraded before
the primary database (in this case a cluster). Once that is done, the
primary environment is then upgraded.
Does the primary need to be upgraded at the same time ? Can it
be upgraded a day or a week later ?
