MQOPEN option for cluster queue

 

To route all messages put to a queue using MQPUT to the same queue manager by the same route, use the MQOO_BIND_ON_OPEN option on the MQOPEN call. To specify that a destination is to be selected at MQPUT time, that is, on a message-by-message basis, use the MQOO_BIND_NOT_FIXED option on the MQOPEN call. If you specify neither of these options the default, MQOO_BIND_AS_Q_DEF, is used. In this case the binding used for the queue handle is taken from the DefBind queue attribute, which can take the value MQBND_BIND_ON_OPEN or MQBND_BIND_NOT_FIXED.

If the queue that you open is not a cluster queue, the MQOO_BIND_* options are ignored. If you specify the name of the local queue manager in the MQOD, the local instance of the cluster queue is selected. If the queue manager name is blank, any instance can be selected. See WebSphere MQ Queue Manager Clusters for more information.
