You can use the CICS messages facility (CICS-supplied transaction CMAC) to provide the messages and codes descriptions online. Before you can use this facility, you must create and initialize the CICS messages data set DFHCMACD, define the resources needed by the facility, and make them available to your CICS region.
For information about creating and initializing the DFHCMACD data set, see Creating the CICS messages data set, DFHCMACI job.
The file DFHCMACD, managed by CICS file controle, accesses the DFHCMACD data set. You must create a definition for this file in the CSD. The CICS-supplied definition for the DFHCMACD file and other resources that are needed by the CICS messages facility are in the CSD group DFHCMAC. The CICS startup procedure (in the IVP jobs) has a DD statement for the CMAC file, but for dynamic allocation you should copy the supplied resource definition for the DFHCMACD file and add the DSNAME option.
You should specify the DFHCMAC group of resources for the CICS messages facility only in those CICS regions that need to use the facility; for example on some terminal-owning regions, but perhaps not on data-owning regions.
