Creating a Batch Image Copy

A batch image copy is a true and exact database backup without any partial updates. It is taken from the database in non-update mode or from the copy created by using the Snapshot General Services. Because it is a true and exact database copy, no other inputs or updates are required when batch image copy is used for database recovery.

A batch image copy is a true and exact database backup without any partial updates. It is taken from the database in non-update mode or from the copy created by using the Snapshot General Services. Because it is a true and exact database copy, no other inputs or updates are required when batch image copy is used for database recovery.
To make a batch image copy, do
one
of the following:
  • Use the existing DFSUDMP0 (IMS Image Copy utility) job and change the STEPLIB or JOBLIB to include the
    Database Management Solutions for IMS
    load library (
    hlq
    .CIMTLOAD) at the front of the concatenation. This approach requires one minor JCL change and creates an image copy the same as DFSUDMP0.
    The database must be in non-update mode by all other users when you run DFSUDMP0. DFSUDMP0 can run concurrently with read-only users but not concurrently with update users or exclusive users because concurrent updates might result in a fuzzy image copy. If update users or exclusive users are accessing the database when DFSUDMP0 starts execution, DBRC does not grant database access to DFSUDMP0 and the job fails with a DFS047A.
  • Code the JCL control statement to let the CIC keyword default or specify CIC=NO.
