Hi all, I'm supporting a development system, and we run multiple versions of z/OS (amongst other things).
One of the systems we run is at z/OS 2.2, and runs JES3. This system is supposed to be our "performance Test" system. One of our developers this morning was complaining about slow response on SDSF. On investigation, I found that all SDSF commands were giving sub-second response times EXCEPT for the LOG command. The LOG command gave up to 18 seconds (timed by my trusty wrist based timepiece) response. Once in the log, PF7, 10 or 11 give good sub-second response, but PF8 to the newest log entry gives 3-4 second response. At the time, the system was NOT using OPERLOG, just SYSLOG. I did a V OPERLOG,HARDCPY command, and now the SDSF LOG command gives sub-second response, as does PF8 to latest log entry (of course, we can only go back in the log to that command being issued). However the SDSF LOG S (force the log command to look at SYSLOG, rather than OPERLOG) command still gives VERY long response times. Can anyone shed any light on what's happening here? Does this suggest there is a problem with the JES3 spool somewhere? Thanks in advance.
