I can't really remember. All the sessions seem to merge together in my memory.
But I seem to think it was a general session on encryption (I hit a lot of encryption and disaster recovery sessions) and he said not to do encryption without buying the encryption processor for your mainframe. I don't know if my shops tend to be so small, they can be easily dis-regarded. Or some of the WAVV speakers where focused on "BIG" shops (z/OS with multiple engines), but some of them needed to talk to the WAVV size shops. For example, I asked on guy (a speaker on CICS/TS) about virtual storage requirements for CICS/TS. (This past weekend we moved 400 users to CICS/TS, which only had 7 users prior to this.) His opinion was the minimum virtual storage you should give to CICS/TS was 2 GB. HUH? Our production CICS/VS 2.3 system, with 2,000 users is running in a 30 MB partition and our programs there are all 24 bit. I didn't say it ran well. At peak times we would do 15 storage compressions per hour. But parsing what he didn't say, I found my answer. Which was that CICS/TS as delivered by VSE has no tuning absolutely necessary. Sure you might have storage compressions (we didn't), but it won't stop CICS/TS, it may just slow it down. My only problem in the last 2.5 days was I didn't redefine the temp stor dataset. The default 9 tracks wasn't sufficient. CICS/TS issued the first warning about 10 am, which gave me time to research and prep. And at 11:30 am we finally froze up. Forced off CICS/TS, redefined tempstor to 50 cylinders with 10 cylinders secondary, forced a cold start and back up, all within 10 minutes. Not bad for our only production outage for this conversion. Ooops, when off on a tangent. Back to the real world.
