A response timeout occurs after the request has been forwarded to the CICS® server.
It can happen to a synchronous call, an asynchronous call, or to the reply
solicitation call that retrieves the reply from an asynchronous call.
This can happen for the following reasons:
- The call was intended to be the only call of a new LUW. The LUW was started,
but the user application cannot determine whether updates were performed,
and whether they were committed or backed out.
- The call was intended to end an existing LUW. The LUW has ended, but the
user application cannot determine whether updates were performed, and whether
they were committed or backed out.
- The call was intended to continue or to end an existing LUW. The LUW persists,
and changes to recoverable resources are still pending.
