Frank is in Munich this week, attending the Technical University conference. The agenda looks really exciting, with sessions on the latest enhancements to WLM and RMF, a load of sessions about controlling software costs, hot topics like Blockchain and Spark, the latest hardware (z13s and DS8880), Parallel Sysplex (of course!), Bob Rogers’ ever-popular Sysprog Goody Bag, Harald Bender’s four sessions on the zEvent Mobile application, and many many others. Frank told me that he needs to master bi-location in order to get to all the sessions he would like to attend. If you are at the conference, please drop in to one of Frank’s three sessions to say hello:
- Wednesday, 13:45 Session z011838 in the Barcelona room, Containing MLC Costs For Mobile Workloads
- Thursday, 08:45 Session z011839 in the Munich room, The Watson & Walker zRoadshow
- Friday, 11:30 Session z011839 in the Partenkirchen room, The Watson & Walker zRoadshow (a repeat of Thursday’s session)
Also, while I’m here, I would like to point out a mistype in Chery’sl List #188. Item number 3 mentioned a recent APAR to improve the performance of the IFASEXIT program (used when you specify SUBSYS=LOGR to read directly from an SMF log stream). The APAR number should have been OA49157 (http://www-01.ibm.com/support/docview.wss?uid=isg1OA49157). Thanks to Ian Burnett from the CICS Performance team for pointing that out. Also, a small update on that APAR – we have since heard that the performance changes to the program are expected to reduce its CPU consumption by between 40% and 50%. One of our readers reported that one of their jobs that uses that exit burns through 18 minutes of CPU time every day, so applying the PTF for that APAR should give them a nice little savings.
That’s all for now. Stay Tuned.
