Problem summary

• ****************************************************************
  * USERS AFFECTED:                                              *
  * IMS 15 customers using OTMA FASTTPCU function.               *
  ****************************************************************
  * PROBLEM DESCRIPTION:                                         *
  * When OTMA FASTTPCU is activated with MQ Series tpipe in      *
  * shared queues, the MQ Series tpipe is incorrectly deleted    *
  * after two checkpoints. The MQ Series tpipe should always be  *
  * active, even after IMS is checkpointed. After the MQ Series  *
  * tpipe is down due to FASTTPCU error, the customer tries to   *
  * continue to use the tpipe, which caused the "DFS7438E        *
  * SEQUENCE NUMBER ERROR ON TPIPE=XXXXX MEMBER=MQ. TPIPE HAS    *
  * BEEN STOPPED" error.                                         *
  *                                                              *

  ****************************************************************
  * RECOMMENDATION:                                              *
  * INSTALL CORRECTIVE SERVICE FOR APAR/PTF                      *
  ****************************************************************
  

Problem conclusion

• OTMA module DFSYCKP0 was enhanced so that the FASTTPCU checking
  for MQ Series tpipe in shared queues will not bring the tpipe
  down.
