This is my CMAS region. Has anyone else experienced this? Also, it seems like transaction WMSC keeps getting invoked and not running due to the MXT condition.

    Hello,

    It does appear that something is holding up the CMAS region. Would you be able to just start the CMAS and WUI only and see whether you can logon to each region and connected to the WUI on its own? Hopefully this might narrow down the issue with a simple setup. If the error still occurs and you are unable to logon to the region then its probably time to get into a CICS system dump to try and identify the task that is causing the region to stall.

    If you take a system dump of the region and format it using the CICS dump formatter (either using IPCS or JCL) and format off the KE part of the dump I suspect that there will be one or more tasks that is in a **RUNNING** state. Hopefully that might help to narrow down the task that is causing the stall.

    Cheers

      As you suggested I only have the CMAS and the WUI regions running.
      I can log on the the WUI region.

      I don't have the CMAS set up to log on to but I suspect even if I did I wouldn't be able to because as soon as I start it the region goes into a max tasks state.

      I did take a dump of the region and formatted it with IPCS. There are no tasks RUNNING.

      I did get an aux trace. I see trace entries like DS 0004 and CC 2050. Here's a sample...

      DM RO LM 0004 LMLM EXIT LOCK/OK
      DM RO LD 1003 LDLD1 EVENT PRE-SVC-CALL LLACOPY
      DM RO LD 1004 LDLD1 EVENT POST-SVC LLACOPY,OK
      DM RO LM 0003 LMLM ENTRY UNLOCK 1B1BEEF0,SHARED
      DM RO LM 0004 LMLM EXIT UNLOCK/OK
      DM RO SM 0301 SMGF ENTRY GETMAIN 1B264EE4 , 0000002D,1748,NO
      DM RO SM 0302 SMGF EXIT GETMAIN/OK 1B5FE000,1800
      DM RO LD 1003 LDLD1 EVENT PRE-SVC-CALL LOAD,DFHEMS,1B5FE000
      DM RO LD 1004 LDLD1 EVENT POST-SVC LOAD,OK,DFHEMS,1B5FE000
      DM QR LD 0002 LDLD EXIT ACQUIRE_PROGRAM/OK 9B5FE114,1B5FE000,1748
      DM QR LD 0001 LDLD ENTRY ACQUIRE_PROGRAM DFHMCP1$,NO
      DM QR CC 2010 CCCC ENTRY GET 1B11EDC8 , 00000000 , 00000010,LD_PDEFN,DFHMCP1$
      DM QR DS 0004 DSSR ENTRY WAIT_MVS CCVSAMWT,1B1504C0,NO,IO,ASYNRESP
      DM QR DS 0005 DSSR EXIT WAIT_MVS/OK
      DM QR CC 2050 CCCC EXIT GET/EXCEPTION RECORD_NOT_FOUND,1B11EDC8 , 00000000 , 00000010
      DM QR PA 0101 PAGP ENTRY INQUIRE_START
      DM QR PA 0102 PAGP EXIT INQUIRE_START/OK COLD
      DM QR LD 0002 LDLD EXIT ACQUIRE_PROGRAM/EXCEPTION PROGRAM_NOT_DEFINED,9B5FE114,1B5FE000,1748
      DM QR LD 0001 LDLD ENTRY DEFINE_PROGRAM DFHMCP1$,RESIDENT,NUCLEUS,YES
      DM QR CC 2010 CCCC ENTRY GET 1B11EDC8 , 00000000 , 00000010,LD_PDEFN,DFHMCP1$
      DM QR DS 0004 DSSR ENTRY WAIT_MVS CCVSAMWT,1B1504C0,NO,IO,ASYNRESP
      DM QR DS 0005 DSSR EXIT WAIT_MVS/OK
      DM QR CC 2050 CCCC EXIT GET/EXCEPTION RECORD_NOT_FOUND,1B11EDC8 , 00000000 , 00000010

      Does this tell you anything?

      I ended up cancelling the region since the only command I could issue from the console was CEKL.

      The end of the aux trace looks like this:
      COMMAND INPUT ===> SCROLL ===> CSR
      TCP QR AP 4D01 CQCQ EXIT MERGE_CIB_QUEUES/OK
      TCP QR AP 4D00 CQCQ ENTRY GET_CIB
      TCP QR AP 4D01 CQCQ EXIT GET_CIB/EXCEPTION CIB_QUEUE_EMPTY,00000000,00000000
      TCP QR DS 0004 DSSR ENTRY WAIT_OLDW TCP_NORM,00049DD0,CSTP,NO,IDLE,DFHZDSP
      TCP QR DS 0005 DSSR EXIT WAIT_OLDW/OK
      TCP QR XM 0801 XMSR ENTRY INQUIRE_MXT
      TCP QR XM 0802 XMSR EXIT INQUIRE_MXT/OK 1E,1E
      TCP QR AP 4D00 CQCQ ENTRY MERGE_CIB_QUEUES
      TCP QR AP 4D01 CQCQ EXIT MERGE_CIB_QUEUES/OK
      TCP QR AP 4D00 CQCQ ENTRY GET_CIB
      TCP QR AP 4D01 CQCQ EXIT GET_CIB/EXCEPTION CIB_QUEUE_EMPTY,00000000,00000000
      TCP QR DS 0004 DSSR ENTRY WAIT_OLDW TCP_NORM,00049DD0,CSTP,NO,IDLE,DFHZDSP
      TCP QR DS 0005 DSSR EXIT WAIT_OLDW/OK
      TCP QR XM 0801 XMSR ENTRY INQUIRE_MXT
      TCP QR XM 0802 XMSR EXIT INQUIRE_MXT/OK 1E,1E
      TCP QR AP 4D00 CQCQ ENTRY MERGE_CIB_QUEUES
      TCP QR AP 4D01 CQCQ EXIT MERGE_CIB_QUEUES/OK
      TCP QR AP 4D00 CQCQ ENTRY GET_CIB
      TCP QR AP 4D01 CQCQ EXIT GET_CIB/EXCEPTION CIB_QUEUE_EMPTY,00000000,00000000
      TCP QR DS 0004 DSSR ENTRY WAIT_OLDW TCP_NORM,00049DD0,CSTP,NO,IDLE,DFHZDSP

      So I'm not entirely certain what's going on other than the longer I leave the region running the more WMSC transactions seems to appear. Since the region is at max tasks nothing is getting dispatched since it looks like everything is on the QR TCB.

        Have you set a MXT limit in your CMAS SITs ?

          Yes, I have my region coming up with MXT=500 but I seem to remember that the developers trial is somehow limited to 30.

            Can you try without the MXT set in the CMAS please.

              Also what happens if you just start the CMAS on its own ?

                I removed my SIT over ride of MXT=500. I'm using the SIT6$ which has a MXT=20. I started the CMAS so that was the only CICS region running. I'm still at max tasks.

    The reason the region was going into max tasks condition was due to the method I used to start the region. I was using a PLTPI that contained program EYU9XLCS and I didn't specify CPSMCONN=CMAS in the SIT so this value defaulted to NO. I changed my SIT override to PLTPI=NO. I added CPSMCONN=CMAS to the SIT overrides also and restarted the region. I didn't get the max tasks condition and my SIT override of MXT=500 was now in effect (where before I was being forced to MXT=30 by CICS itself). Once the region started I issued a CEMT I TAS to it just to see how many tasks were running. There were 37 just to support CICS.

    Thanks to all the fine folks who monitor this forum and provide excellent assistance.

      Hi

      Great to hear you are up and running with the Developer Trial.

      Cheers
