Error description

• ISPF online monitor OLM CRD to handle multiple start trace
  sequences.
  .
  The problem can be recreated by using the OMPE V510 ISPF OLM
  function "DB2 command input" only, by using 2 TSO sessions.
  - In TSO session 1 start OLM and use DB2 cmd input panel
  - Stop all traces
  - DISPLAY TRACE(*) will show:
    DSNW137I  -D911  SPECIFIED TRACE NOT ACTIVE
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
  - Start a 1st PERFM trace:
    START TRACE(PERFM) DEST(OPX) CLASS(18)
    DSNW130I  -D911 PERFM TRACE STARTED, ASSIGNED TRACE NUMBER 01
    DSN9022I  -D911 DSNWVCM1 '-START TRACE' NORMAL COMPLETION
  - DISPLAY TRACE(*) will show:
    DSNW127I  -D911 CURRENT TRACE ACTIVITY IS -
    TNO TYPE   CLASS        DEST QUAL IFCID
    01  PERFM  18           OP1  NO
    *********END OF DISPLAY TRACE SUMMARY DATA*********
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
  .
  - In TSO session 2 start OLM and use DB2 cmd input panel
  - DISPLAY TRACE(*) will show the same as in session 1:
    DSNW127I  -D911 CURRENT TRACE ACTIVITY IS -
    TNO TYPE   CLASS        DEST QUAL IFCID
    01  PERFM  18           OP1  NO
    *********END OF DISPLAY TRACE SUMMARY DATA*********
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
  - Start a 2nd ACCTG trace:
    START TRACE(A) D(OPX) BUFSIZE(1024) C(03)
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
    DSNW130I  -D911 A TRACE STARTED, ASSIGNED TRACE NUMBER 02
    DSN9022I  -D911 DSNWVCM1 '-START TRACE' NORMAL COMPLETION
  - DISPLAY TRACE(*) will show that OP1 is used.
    DSNW127I  -D911 CURRENT TRACE ACTIVITY IS -
    TNO TYPE   CLASS        DEST QUAL IFCID
    01  PERFM  18           OP1  NO
    02  ACCTG  03           OP1  NO
    *********END OF DISPLAY TRACE SUMMARY DATA*********
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
  - Start a 3rd RERFM trace using the same OPn from 2nd ACCTG
  trace:
    START TRACE(P) D(OP1) BUFSIZE(1024) C(06,07,17,20,21)
    DSN9022I  -D911 DSNWVCM1 '-DISPLAY TRACE' NORMAL COMPLETION
    DSNW184I  -D911 OP BUFFER OP1 NOT AVAILABLE
    DSN9023I  -D911 DSNWVCM1 '-START TRACE' ABNORMAL COMPLETION
  ===============================================================
  DB2 development informed the following rules, ie.
  "The rules are this:
  1. The same OP buffer can be shared if the starter of the trace
  is the same agent.  This agent already owns the buffer and can
  presumably make a decision to add addtional trace data to that
  buffer OR
  2. If the trace does not produce real output (i.e., is just a
  bunch of internal switches), it will pick OP1 even if from a
  different agent.  Since the trace isn't going to generate IFCID
  records, the OP buffer doesn't matter."

  PROBLEM SUMMARY:
  Some tasks are using the DB2 OP buffers. The ISPF Collect
  Report Data task is just one of these tasks. Sometimes the
  error message "DSNW184I ssid OP BUFFER OPn NOT AVAILABLE"
  occurs for DB2 V9 or V10.
  
  PROBLEM CONCLUSION:
  The logic to get a free OP buffer number was changed from
  "START TRACE DEST(OPX)" to "DISPLAY TRACE output analysis".
