I went through and lined up the various pieces that I've discovered so far... 10171 21:18:24.44 SYSLOG 00000000 IEE042I SYSTEM LOG DATA SET INITIALIZED 10171 21:18:30.79 STC03994 00000080 IST093I APTCP ACTIVE 10171 21:20:35.66 STC04089 00000084 $HASP373 TESTTRN STARTED 10171 21:20:35.63 STC04088 00000084 $HASP373 TESTOLD STARTED 10171 21:21:24.56 STC04120 00000000 IEF403I TN3270D - STARTED 10171 21:22:38.42 STC03994 00000084 IST663I INIT OTHER REQUEST FAILED, PCOPO3 10171 21:22:38.42 STC03994 00000084 IST663I INIT OTHER REQUEST FAILED, PCOPO4 10171 21:22:39.72 STC03994 00000084 IST663I INIT OTHER REQUEST FAILED, PCOPO6 While the production CICS's actually start earlier, they are much larger and take a longer to initialize. Maybe that's what allows them to connect up OK while the test terminals consistently don't ??? TN3270 seems to be ready about a second prior to the terminals being accessed, so this might not be the cause. It's close enough to give it a shot though. In any event, I moved the TN3270 start up prior to the CICS start ups. That should give it enough time to complete initialization prior to CICS looking for them. But VTAM is activating them prior to that. Is this the proper sequence ??? VTAM --> TN3270 --> Applications ??? It seems logical to me, but this whole quest has been an experience... ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
