Cluster configuration screen shows 9i RAC Present

When installing Oracle 10gR2 RAC on AIX, cluster configuration screen was showing ‘Yes’ in ‘9i RAC Present’ column. I was bit surprised, as I never installed any 9i software on the cluster.

Later I discovered that I didn’t cleanup few files from previous install of 11gR1. If these configuration files are present (version higher or lower), installer treat them as 9i. Cleaned up following files and it stopped showing 9i RAC presence.

# cd /tmp/.oracle (holds socket files)
# rm -rf *

# cd /var/tmp
# rm -rf *

# cd /etc
# mv oracle oracle.old
# mv oratab oratab.old

Need to provide platform specific locations of oratab & oracle related configuration files.
