Database Error Messages

OCI-19765

mount ID mount_id1 does not match mount ID mount_id2 in control file
  • mount_id1: The mount ID found in the change tracking file.
  • mount_id2: The mount ID found in the control file.

Cause

The change tracking file did not match the one that was present when this instance was opened. In Oracle Real Application Clusters (Oracle RAC), this error is most likely caused by a change tracking file that cannot be consistently updated by all instances.


Action

In Oracle RAC, ensure that the name specified for the change tracking file represents the same disk location for all nodes in the cluster. Disable and then re-enable change tracking.
