14a Evaluate and implement user catalogs and policies.
You must perform this step at initial installation. For migration, you must verify or perform this step if you determine that it has not yet been completed in your current environment.
OAM collection names are defined by entries in a user catalog or catalogs. The collection entries in this catalog are made automatically by OAM when the first object is stored to a new collection. Define and maintain the catalogs or catalog aliases using IDCAMS and your installation’s standard catalog maintenance procedures. Because access to the collection name entries is essential to OAM operation, ensure that these user catalogs are included in your standard backup and recovery procedures. If you are in an OAMplex, you should have a shared catalog for the collection entries to avoid errors with collections in the DB2 table that are not in the catalog. It is possible to maintain separate catalogs, but that is not the preferred method due to the inconvenience factor.
If no new collections are created, there is no need to share a catalog. It is necessary, in this case, to make sure that all OAMs within the same OAMplex have identical catalog entries in their respective catalogs.
