Online installation of catalog non-structural changes on an IMS system where managed ACB is not enabled

Find the maintenance procedure for online installation of catalog non-structural changes on an IMS system where managed ACB is not enabled.

You must have reviewed the information in Prerequisite considerations.

Perform the following steps to install non-structural changes to the catalog while IMS is online or active and the managed ACB is not enabled and use the local online change process for a single system or the global online change process for multiple systems.

Procedure

  1. Run the DFS3UACB utility to perform an ACBGEN and to populate the new DFSCD000 instance in the IMS Catalog.
  2. Copy the new DFSCD000 from the IMSACB data set to the appropriate inactive online ACBLIBx.
  3. Take the database offline by using the following command: /DBR DB DFSCD000 or UPDATE DB NAME(DFSCD000) STOP(ACCESS)
  4. Run the appropriate online change command.
  5. Resume access to the IMS catalog databases with the following command: /STA DB DFSCD000 or UPDATE DB NAME(DFSCD000) START(ACCESS)

The maintenance that provides the catalog resource changes might include post activation procedures. This might include running the IMS Catalog Maintenance utility (DFS3CM00) to update data in the catalog database. You might have to refer to the maintenance hold cards for the post activation steps.
