The DCM delimiter can be changed after the database
has been initialized to use DCM. This change must be applied
to all databases in the DCM cluster.
This change can require that many objects are updated.
Perform it early when the number of databases and objects requiring
update in the cluster is small. If you have a large cluster or large
databases, this operation takes some time and requires careful planning.
Verify that you have a current and usable backup of each database
in the cluster before proceeding.
The steps to
perform a change of DCM delimiter are:
- Notify all DCM administrators of the intended change
of DCM delimiter and coordinate a good time to perform the change.
- Suspend all DCM operations in the cluster.
- In each database in the cluster, use the Change
DCM Delimiter option. Coordinate with remote administrators
who perform this operation on the databases at their location.
- When you have received confirmation from all DCM
administrators that all databases have been successfully updated,
notify all administrators that the change is complete. They can resume
DCM operations.
- Resume any DCM operations local to your site.
