//TLMSJCL DD statements referencing a DSEXTLMS job

Products

• Dispatch Output Mgmt

Issue/Introduction

We do not use CA TLMS as our sites tape management system.

However, we see "//TLMSJCL  DD  DSN=&JCLLIB(DSEXTLMS),DISP=SHR" JCL references in the following CA Dispatch PROCs:

 

CADSDISP - CA Dispatch Main region task procedure

CADSXTAR - External Archive task procedure

CADSARB(L) - Archive DUPLICATE processing procedures

CADSARC(L) - Archive Condense/Consolidation procedures

Should these JCL references be commented out since we are not using CA TLMS? 

Environment

Release: DISPAX00200-11.7-Dispatch
Component:

Resolution

No, there is no need for you to either COMMENT out or "DUMMY OUT" these //TLMSJCL DD DSN=&JCLLIB(DSEXTLMS),DISP=SHR references.

These statements must remain in the JCL in order to avoid JCL ERRORS when executing these utilities.

The only Dispatch clients who would need to setup the DSEXTLMS job and include legitimate //TLMSJCL statements in their JCL are clients who are using CA TLMS to manage their CA Dispatch archive tapes and who ALSO have option 2 (2=Online TLMS) specified as their “Tape Management System” on the CA Dispatch VSGMU210 - Sysgen Archive Control Information Screen (Option 9.A from the main menu).

* If you do not specifically have option 2 specified (2=Online TLMS) as your tape management system on the VSGMU210 screen, then the //TLMSJCL DD statement JCL references to the DSEXTLMS job will be completely ignored.

Additional Information

* Please be aware that because of the following noted limitations when using Tape Management System option 2 (2=Online TLMS) on the CA Dispatch VSGMU210 screen, it is NOT the preferred option for most clients: 

Note: One limitation is that report retention must be maintained by days (not generations) for this approach to be utilized. An additional limitation is that retention changes made MANUALLY in CA Dispatch are not reflected in CA Dynam/TLMS.

* Alternatively, clients who use CA TLMS to manage their Dispatch archive tapes may prefer to use TLMS option 4 (4=Batch TLMS or TLMS EDM if apars RO79236 and RO82687 are applied) as these options do not have the same limitations as TLMS option 2.
