"mount id %s does not match mount id %s in control file"
*Cause: The change tracking file does not match the one that was present
when this instance was opened. In RAC, this error is most likely
caused by having a change tracking file that cannot be
consistently updated by all instances.
*Action: In RAC, ensure that the name specified for the change tracking
file truly represents the same disk location for all nodes in
the cluster. Disable then re-enable change tracking.
