APAR status

• Closed as program error.

Error description

• After consumer application ends, the system goes into loop of
  of sending makeconnection messages every 3 seconds. It then
  sends a retry Notify message. Adjusting the setting in the
  "Exception destination" section of the destination panel,
  of 'Override messaging engine blocked retry timeout default'
  , 'Blocked retry timeout in milliseconds' and 'Maximum failed
  deliveries per message' has no affect on this behavior.
  WS-RM only uses SIB as a storage mechanism, not the
  Pub-Sub function it provides.

  ****************************************************************
  There is no mechanism to adjust the frequency with which WS-RM
  sends MakeConnection requests and re-transmits application
  messages adversely effecting the ability to performance tune the
  system.
  

Problem conclusion

• The APAR provides two JVM system properties:
  
  com.ibm.websphere.wsrm.pollingInterval can be set to specify the
  frequency with which MakeConnection requests are made for a
  Sequence.  The value specifies the interval in milliseconds.
  The default behavior when the property is not set is 3000 ms.
  
  com.ibm.websphere.wsrm.retransmissionInterval can be set to
  specify the frequency with which WS-RM re-transmits application
  messages when previous attempts to transmit the message have
  failed.  The value specifies the interval in milliseconds.  The
  default behavior when the property is not set is 15000 ms.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 7.0.0.29, 8.0.0.7 and the fix pack following 8.5.0.2.
