The messages described in this section are written to the CICS BAC audit log by the CICS® request server, or by the batch request utility if it services a command directly because the target CICS region is not available. Expressions such as “written by CICS BAC” , or similar, are used generically in the message explanations to mean either one of these two components. The DD name for the audit log is CBKLOG.
The CICS region and the batch request utility job step dynamically allocate the audit log, based on the audit log attributes in the CICS region properties. You can define, view, or alter the audit log attributes using the workstation administration client, opening the Region Properties window and selecting the Miscellaneous options tab.
