MQSET and clusters

The MQOPEN option MQOO_SET option requires there to be a local instance of a cluster queue for MQSET to succeed.

We cannot use the MQSET call to set the attributes of a queue elsewhere in the cluster.

We can open a local alias or remote queue defined with the cluster attribute and use the MQSET call. We can set the attributes of the local alias or remote queue. It does not matter if the target queue is a cluster queue defined on a different queue manager.
