Recovery from connection failure

If the communications connection fails before a response message is received, the client can reconnect to the same router and request that the message be sent again.

To do this, your client program must set the value of the BRIH-TRANSACTIONID field to BRIHT-RESEND-MESSAGE, and set BRIH-FACILITY to the value returned by the allocate request. Other fields in the message are ignored.

If successful, the outbound Link3270 bridge Message will contain as much of the message as can be fitted into the COMMAREA. If either the router or the AOR CICS® region has failed, the message returned indicates that the facilitytoken is unknown.

If unsuccessful, the output is the BRIHT-RESEND-MESSAGE message with an appropriate BRIH-RETURNCODE.

Note:
  1. A resend request must be sent before the interval specified in BRIH-FACILITYKEEPTIME on the allocate request has expired. Otherwise, both the bridge facility and the outstanding message are deleted.
  2. You can use the field BRIH-SEQNO to check whether the previous request has worked.
