FAQ
Hi All,

Scenario: I'm trying to install 9i rac on a 2 node cluster on OCFS2
OS: Oracle enterprise linux

To my understanding, OCFS2 supports shared home installs which to my
knowledge is not only can i have datafile and control files but also
clustermanager files and binaries (pretty much everything: no files or
executables need to kept local to any nodes). I have one single shared
file for $ORACLE_HOME/oracm/admin/cmcfg.ora for both the nodes.

cat cmcfg.ora
ClusterName=Oracle Cluster Manager, version 9i
MissCount=620
PrivateNodeNames=sunny1prv sunny2prv
PublicNodeNames=sunny1pub sunny2pub
ServicePort=9998
CmDiskFile=/u01/oradata/orcl/cmquorumfile
HostName=sunny1pub
KernelModuleName=hangcheck-timer

I started cluster manager on node1 with the value of
HostName=sunny1pub Now to start the cluster manager on node2, the
value of HostName should be sunny2pub. What do i do now? Do i have the
cluster manager files separate or am i missing out something ? Any
help is greatly appreciated. Thanks in advance.

    There's documentation on this, but basically you need to look up how CDSL works on OCFS2. You can effectively have one file that looks like a different file on each node via symbolic links

    That being said, I don't recommend sharing your cluster installs. Easier to just have two installs.
