Greetings,
I would like to know if there is a CMS command/program out there that can quickly determine if a CMS disk has been changed? The reason: We run the ASG ZEKE product that runs in our z/VSE machines that communicate via a SMSG to a CMS machine that actually sends the JCL to the reader of the requestor. The JCL could be on several CMS disks so I have added CMS ACCESSes each time a SMSG comes in. Here is the console from a ZEKE CMS machine: DMSCYW2245I *SMSG MUHC24 00236 EPIBCATZ BKUP EPIBCATZ 03 0 NONE NONE * Z TIME IS 07:04:15 EST MONDAY 2010-03-08 CONNECT= 99:59:59 VIRTCPU= 000:14.36 TOTCPU= 000:21.53 DMSACC724I 193 replaces B (193) DMSACP723I B (193) R/O DMSACC724I 194 replaces C (194) DMSACP723I C (194) R/O DMSACC724I 195 replaces E (195) DMSACP723I E (195) R/O DMSACC724I 196 replaces F (196) DMSACP723I F (196) R/O JOB INFO FROM MUHC24 WAS EVENT 00236 FNAME EPIBCATZ FTYPE BKUP -------- -------- ----- JOB EPIBCATZ PRI 03 SYSID CLASS 0 -------- -------- ----- USERINFO NONE NONE SUBMIT Z TARGET MUHC24 PUN FILE 7783 SENT TO MUHC24 RDR AS 9406 RECS 0012 CPY 001 Q NOHOLD NOKEEP ZEK11E000I PROCESSING COMPLETE. OUTPUT RECORDS=12 Those ACCESSes , probably 98% of the time, don't have to be done (since the JCL doesn't change that often) but we issue them just in case a disk or disks change. We have a problem when ZEKE requests from VSE machines start coming in quickly and the CMS machine(s) just can't keep up with them. ZEKE complains with a message on the z/VSE console: Z2 0074 Z0641E Event 000078 ver 00000 dispatch attempted-CMS machine not receiving I know I can go SFS for those disks but we don't have it set up and to do it for this problem I'm not too keen on it (probably because I'm old and lazy and the need to educate the schedulers is too much trouble). So, I'm looking for a (super)quick resident CMS module that given a virtual disk address can tell if that CMS disk needs to be re-accessed. Has it been written already and, if not, which manual(s) would have the info for me to write it? Thank you, Mike Horlick Conseiller CGI Gestion Intégrée des Technologies 1350 Boul.
