PubSubSyncPoint (MQLONG)

Whether only persistent messages or all messages are processed under syncpoint.

MQSYNCPOINT_IFPER

This makes the queued publish/subscribe interface receive non-persistent messages outside syncpoint. If the daemon receives a publication outside syncpoint, the daemon forwards the publication to subscribers known to it outside syncpoint.

This is the default value.

MQSYNCPOINT_YES

This makes the queued publish/subscribe interface receive all messages under syncpoint.

To determine the value of this attribute, use the MQIA_PUBSUB_SYNC_PT selector with the MQINQ call.
