IT32961: SWITCH SERVER MAY NOT CLEAR ENTRIES UNDER INFLIGHTCALLABLEFLOWREQUESTS TILL IT RESTARTS.

APAR status

• Closed as program error.

Error description

• One can use the following command to find the in-flight
  requests from callable invoke nodes
  
  mqsireportproperties
  IIBSWITCH_NODE -e IIBSWITCH_SERVER -o
  ComIbmIIBSwitchManager/Switch -r
  
  However its seen that in
  scenarios where the invoke nodes times out awaiting response
  from CallableInput flow, the inflightCallableFlowRequests
  entries are not cleared from switch server till it restarts.

Problem conclusion

• The product now provides two new fields in  the <span
  style="background-color:rgb(255, 255,
  255)">inFlightCallableFlowRequests output named
  '</span>creationTime' and 'expired' to indicate whether the
  inflight requests are alive or timed out. The new output is of
  the form
  
       inFlightCallableFlowRequests
          Item
            flowName='CallableInput:Dummy'
  
  trackingId='43414c4c03000000060000003b50c27fdc37000000000000'
