WMQ 7.0.1 : Reconnexion automatique du client MQ

Une nouvelle TechDoc disponible sur ce sujet assez pointu !

Abstract
The objective of this techdoc is to show real examples that use MQI (C Code) that exploit the new feature introduced in WebSphere MQ 7.0.1: Automatic Client Reconnect.

There are several mechanisms that specify how a client will do the automatic reconnection. This is the order of reconnection:

1) MQCNO flags for MQCONN – this is not shown in this document (these flags are specified inside an application).

2) If MQSERVER is present, then it is used. It overrides all the options 3 and 4.

3) If the MQSERVER is NOT present, then the next option is to use the Client Configuration File (mqclient.ini).

4) Finally, if none of the above is defined, then the CCDT is used.
