CA-Disk (Formerly DMS/OS)

Use the steps described below to activate the CA-Disk interface to Control-M/Tape.

The TMSCTLEX exit is called by CA-Disk whenever a tape volume no longer contains any valid data. The exit marks the volume as scratch in the Media Database and, optionally, interfaces with the automated tape library at the site.

1. If you are currently not using the TMSCTLEX exit, continue with Step 2 below.

   If this exit is already in use at your site (meaning, by another tape management system), use the following steps to integrate your current TMSCTLEX exit with the Control-M/Tape exit in Global Test and Global Phased modes. You should stop using your other product’s TMSCTLEX exit when you first activate Control-M/Tape in Global Production mode.

   1. Rename the load module of the TMSCTLEX exit currently in use at your site. You cannot have two exits with the same name in the CA-Disk LOAD library.
   2. Change all occurrences of keyword $TMSEXT$ in the TMSCTLEX sample member that is supplied with Control-M/Tape to the exit name you chose in step A.
   3. "Uncomment" the lines marked *CALLEXIT by replacing the asterisk in the first column with a space.
2. Install CA-Disk Support using the ICE Automatic Exit Installation Tool to compile the TMSCTLEX member. For details about this tool, see the exits chapter of the INCONTROL for z/OS Administrator Guide.

   The EDM now calls the TMSCTLEX exit supplied with Control-M/Tape that in turn calls the old TMSCTLEX (that has been renamed).

   CA-Disk receives a return code from the exit that communicates with the old tape management system. (This exit was originally named TMSCTLEX.)

3. Verify that the IOA LOAD library is defined as one of the CA-Disk STEPLIB libraries or one of the system’s LINKLIST libraries.
4. Make sure that DO RETENTION=EDM statements are included in rules for the data sets created by CA-Disk. This statement indicates that the data sets indicated in the selection criteria of the rule are EDM-controlled. Job names, data set names, program names, or volsers can be used as selection criteria by the rules.
