To generate VTAM® generic resource support for your CICS® TORs, you must:
For example:
GRNAME=CICSH###
For details of the GRNAME system initialization parameter, see the CICS System Definition Guide. The CICS naming conventions are described in the System/390 MVS Sysplex Application Migration manual.
If CICS has not been shut down cleanly before you try to register it as a member of a generic resource, VTAM may (due to the existence of persistent sessions) fail to register it, and issue a return code-feedback (RTNCD-FDB2) of X'14', X'86'. (VTAM RTNCD-FDB2s are described in the OS/390 eNetwork Communications Server: SNA Programming manual.) To correct this, you must restart CICS (with the same APPLID), and use a CEMT PERFORM SHUTDOWN NOSDTRAN command to shut it down cleanly. Alternatively, if you have written a batch program to end affinities (see topic Writing a batch program to end affinities), you might be able to use it to achieve the same effect. As part of its processing, the skeleton program described in topic Writing a batch program to end affinities opens the original VTAM ACB with the original APPLID, unbinds any persisting sessions, and closes the ACB.
