Handling request timeouts

In asynchronous mode, requests time out if they do not complete within the time that is specified by the asyncRequestTimeout attribute on the zosconnect_zosConnectManager element in server.xml.

If the processing of a request is timed out, the client receives a 503 HTTP response code. The CICS® service provider terminates processing of the request and the associated IPIC session is freed. The time to process the first request that is sent to any CICS server includes the time taken to establish the IPIC connection. This time must be considered when the value of the asyncRequestTimeout attribute is set.
