PK52490: OTMA CI RC4 RSN1(12) RSN2(0) RSN3(-1) RSN4(10) WHEN USING DSNAIMS SEND ( ASYNC, SEND ONLY, SUPPORT ) AFTER PK24556 (DB2)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• After DB2 DSNAIMS apar PK24556, customer using DSNAIMS
  SEND ( as opposed to SENDRCV ) call for CM0 async message
  and using different TPIPE names on separate invocations
  encounters DSNA317I and OTMA C/I RC4 RSN1(12) RSN2(0)
  RSN3(-1) RSN4(10).
  The reason is PK24556 changed DSNAIMS to specify a single
  session on the OTMA_OPENX call. This doesn't matter for CM1
  processing since OTMA_CI will dynamically obtain sessions as
  needed, (up to 999 ) but for CM0 processing once a TPIPE name
  is associated with a session, that session cannot be used
  for a SEND with a different TPIPE name.
  

Local fix

• Use a common TPIPE name for all DSNAIMS SEND ( ASYNC, CM0,
  SEND-only ) flows if possible.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All of IMS V10 customers using OTMA C/I      *
  ****************************************************************
  * PROBLEM DESCRIPTION: OTMA C/I async calls failed when        *
  *                      invoked by DSNAIMS stored procedures    *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  OTMA C/I asyc calls, such as otma_send_async
  and otma_receive_async calls, cannot dynamically allocate
  free session blocks when the session limit is reached.
  In the case of DB2 DSNAIMS, the session limit
  was set to 1 and the session was used. The subsequent
  OTMA C/I asyc call tried to get a free session and failed.
  

Problem conclusion

• AIDS: RIDS/SYS RIDS/CNTRL SYS CNTRL
    GEN:
  
  *** END IMS KEYWORDS ***
  
  DFSYOUSE module was enhanced to dynamically
  allocate a free session when the session limit is reached.
