Installing parallel EDM support with earlier Control-M/Tape versions

The Tape Volume exit that is currently used must be changed in order to support activation of version modules in the version you are upgrading from and in the current version.

Note: Ignore the source exit header remarks in the earlier Control‑M/Tape version. Those remarks may be different from the instructions below.

Modify the Tape Volume exit source as follows:

1. Create a load module for the Tape Volume exit of the newly installed Control-M/Tape version.

   Use the ICE Automatic Exit Installation Tool (described in the Exits chapter of the INCONTROL for z/OS Administrator Guide) to compile and link the Tape Volume exit of the newly installed Control-M/Tape version. For example, for an DFSMShsm interface, compile the ARCTVEXT source exit.

2. Rename the module created in the newly installed IOA LOAD library in the previous step, in accordance with the following table.

   Table 31 Exit name revisions

   EDM interface	Standard exit name	Renamed exit
   DFSMShsm	ARCTVEXT	ARCTVEXN
   A-Disk	TMSCTLEX	TMSCTLEN
   CA-ASM2	$FTEXIT	$FTEXITN
   ExHPDM	SOVCTTEX	SOVCTEXN

3. Recreate the load module of the old Control‑M/Tape version Tape Volume exit, as follows:
   1. First, save a copy of the prior Tape Volume exit for backup.

      Your earlier Control-M/Tape version is supplied with an exit for parallel processing. Use the following table to find the relevant parallel exit you need to compile.

   Table 32 Parallel support exit table

   EDM interface	Standard exit name	Parallel support exit name
   DFSMShsm	ARCTVEXT	ARCTPRLL
   CA-Disk	TMSCTLEX	TMSCPRLL
   CA-ASM2	$FTEXIT	AS2FPRLL
   ExHPDM	SOVCTTEX	SOVCPRLL

   1. Compile the exit using the instructions in the External Data Managers chapter of the Control‑M/Tape Implementation Guide. Ensure that you compile it in the previous Control‑M/Tape environment. This means using the previous Control‑M/Tape version macro libraries, and the output module created in the previous Control‑M/Tape version IOA LOAD library.
4. Add to the EDM procedure a //LOADPRLL DD statement that references the newly installed IOA LOAD library. The EDM must be stopped and restarted for this change to take effect. The STEPLIB in the EDM procedure will continue to reference the old IOA LOAD library, as it was before the parallel support.
