Stopping tape processing across a sysplex is a nightmare. It really means stopping all batch because even with job class standards there is no guarantee tape jobs won't run if you stop a "tape job class". And not all the sysplexes I support have job class standards based on tape usage and certainly with virtual tape no one has really paid attention to violating those standards in years anyway. I have a hard enough time scheduling rolling IPLs which don't affect most applications, but some batch is affected thanks to priceplex-ing and not having all software available on all LPARs. But at least that is controllable with SCHENV. When my team does need to schedule a change that requires "stopping all batch" for whatever reason, there is always a huge push back from my client. I didn't like the Datacom implementation forced for some CA products years ago, but it did allow for continuous operations or significantly less disruption for maintenance to product files / databases. I'm glad CA-1 did it all without Datacom. :-) Best Regards, Mark -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS ITIL v3 Foundation Certified mailto:[email protected] Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://search390.techtarget.com/ateExperts/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
