A few Oracle clusterware/database utilities depend on "CRS=true" flag in central inventory to determine which is current clusterware home, if the flag is not set or set on wrong home, those utilities will fail. "CRS=true" is allowed to be only on active clusterware home(in upgraded case) as there can be only one active clusterware home per node.

Even the behaviour has changed in latest version of 11gR2 Grid Infrastructure, due to a few known issues, the flag is still needed as a workaround in some case- refer to <Document:1316815.1> for one known issue.

This note provides instructions to update the flag in central inventory.
