The audit log data set

The CICS® region and the batch request utility are both able to use the audit log, DD name CBKLOG, to record the results of processing batch request utility requests. In the case of the batch request utility, it uses the audit log only when it processes requests directly itself because the target CICS region is not available. The level of audit logging, and whether it takes place at all, depends on the options you specify in the CICS region properties object record. Also, unless you specify that log records are written to SYSOUT, you need to define an audit log data set that is referenced by the CBKLOG DD statement. Define your log data set with the following attributes:

You can include a DD statement for CBKLOG in the CICS region JCL or in the CICS BAC batch request utility JCL to allocate the log data set at job step initiation. Alternatively, you can let CICS BAC dynamically allocate the audit log when it is first required, based on the audit log attributes in the CICS region properties record in the region control file. You can define, view, or alter the audit log attributes using the workstation administration client. In the workstation administration client, open the Region Properties window and select the Miscellaneous(1) options tab. The Miscellaneous(1) options tab allows you to direct the audit log to SYSOUT, or to a named data set, and to indicate the types of audit record you want CICS BAC to write to the log. You can also specify the logging attribute using the LOGxxxx parameters of the file maintenance utility (see the UPDATE REGION command ).
