Problem summary

• ****************************************************************
  * USERS AFFECTED: CICS IA 3.1 users who exploit the CICS IA    *
  *                 Command Flow Data.                           *
  ****************************************************************
  * PROBLEM DESCRIPTION: CICS IA presents TCB switching process  *
  *                      incorrectly for the Command Flow data.  *
  *                      Columns TCBMODE, PREV_TCBMODE and       *
  *                      BEFORE_MODESWITCH of                    *
  *                      the CIU_CMDFLOW_DATA table currently    *
  *                      do not show all the TCB swaps that can  *
  *                      happen. CICS IA can not detect all TCB  *
  *                      swaps.                                  *
  ****************************************************************
  * RECOMMENDATION: Apply the PTF and perform HOLD ACTION.       *
  ****************************************************************
  To fix this, two columns were added to CIU_CMDFLOW_DATA table:
  TCB_SWITCH_BEFORE_COUNT The TCB mode switch count. The
                          value of this field is determined
                          before the start of the command
                          and is obtained from CICS
                          Monitoring Domain data.
  TCB_SWITCH_AFTER_COUNT  The TCB mode switch count. The
                          value of this field is determined
                          after the completion of the
                          command and is obtained from
                          CICS Monitoring Domain data.
  Note:
  1.The TCB_SWITCH_BEFORE_COUNT and TCB_SWITCH_AFTER_COUNT fields
    represent the accumulated value of count for CICS
    Dispatcher change-TCB mode request issued from start user's
    task to moment of CICS Monitoring Domain statistics data
    enquiring.
  
  2.A value of -1 in these fields indicates that the TCB switch
    counter data is not available due to the CICS Monitoring
    Domain being deactivated during the command flow collection.
  

Problem conclusion

• Code has been added.
