This blog entry is only of interest for z/VSE 5.1 users.
I just looked into VSAM APAR DY47452. You may remember, that I mentioned it in
one of my previous blog entries.
The problem description says:
1. Missing records when updating KSDS dataset with DFR+LSR options.
2. Gradually eaten-up 31bit Getvis while running CICS transactions actively processing VSAM KSDS files.
DFR is an VSAM ACB option for deferred write, LSR for local shared resources.
If you use DFR, I recommand to apply this PTF.
The 31 bit Getvis issue doesn't free a few bytes, after each iteration. It is applicable for long running
applications in general, not just for CICS.
Sorry, I forgot to add the link to the APAR
