If you want to use DFSMSdss DUMP, you must create a batch
job and set it up so that it is regularly submitted with a production planning
system such as OPC/ESA.
The DUMP job must include the CICSVRBACKUP keyword so that CICS® VR is notified
of the produced logical dump. Your output data set name must be unique each
time the job is run so that you can maintain multiple backup copies of your
VSAM data sets. Three methods of providing a unique output data set name are
discussed:
- Using a batch REXX procedure to modify and submit the JCL
- Using a started task
- Using a generation data group (GDG)
