Good day I have reviewed our SMFDUMP program as well the one in CBTTAPE file 686.
Why is there a GRS ENQ? Is it needed? APAR? documentation? logic? I see those names: SMFQNAME DC CL8'IPOSMF01' SMFRNAME DC CL7'DATASET' and scope is SYSTEM? What will break if I do not use GRS and then fall through RESERVE which is indeed not recommended? The reason is that we sometimes we get a deadly embrace where two SMFDUMP issue those ENQs and then while the system is doing its 'I SMF' things, it still scans the DASD despite that we do not record SMF type 19. In the end I need to cancel one of those SMF jobs, let the other run and retry with possible loss of data. The alternative is that I need to space out those 'I SMF' across the sysplex over longer elapsed wall clock time. Or making those QNAME / RNAME combination unique per LPAR? Will something break? Or making those wait time in SMFDUMP shorter? I'm asking this because the way how 'I SMF' is partly documented. Other question: In our GRSRNLxx is this line: RNLDEF RNL(EXCL) TYPE(GENERIC) QNAME(SYSSMF01) Anyone knows who is using it? Of course you could point me to any documentations. Thanks very much in advance.
