Preparation Steps

The following steps must be performed before the first run of the CTTSBD utility at your site:

1. Allocate and format the CTTSBD utility Checkpoint-Restart data set using the CTTSBF batch job in the Control-M/Tape JCL library.
2. Implement security considerations.

   The CTTSB Control-M/Tape utility reads and writes data sets in the library for your site. Relevant Media database records are subsequently updated. Therefore, the user ID associated with the job or started task that executes the utility must be authorized to

   • Read selected input data sets.
   • Create and write the output data sets (whose names may or may not be the same as the names of the input data sets).
   • Read and update Media database records.

Consult your security administrator to ensure that the required authorization is defined for the user that runs the CTTSBD utility.
