CICS BAC support for record-level sharing (RLS)

CICS BAC provides support for CICS files defined to be used in record-level sharing (RLS) mode, and when a batch request utility command that specifies a file that is currently defined as RLSACCESS(YES) in an active CICS region (in other words, the command will be serviced by the target CICS region). However, this support is not available if CICS BAC is not available in the target CICS region, or the region is unavailable and the command is therefore processed natively by the batch request utility, because CICS BAC cannot determine if the file is defined with RLSACCESS(YES).

CICS BAC RLS processing for a file depends on the CICS BAC RLS access options specified in the file object record in the CICS region control file:

Note:
For details of these RLS options, see the ADD FILE and UPDATE FILE commands on pages ADD FILE and UPDATE FILE respectively.
