CICS BAC provides a file maintenance utility that enables you to maintain a CICS region control file through an MVS batch job. You run the file maintenance utility as a batch job, which passes file maintenance commands to the CICS BAC request server in the target CICS region. If the target CICS region is down, or CICS BAC is not active, the file maintenance utility processes commands directly in the target CICS control file.
The file maintenance utility enables you to create and modify information in a CICS BAC VSAM KSDS control file. You can also list information held in a CICS region control file. For information about this batch utility, see CICS BAC file maintenance utility.
