3.1.1.8.1 Cluster Registry Batch Update Notification Ports

  • Article

A cluster registry batch update notification port is a first-in, first-out queue containing indications that some portion of the cluster registry has changed. A cluster registry batch update notification port is not part of the nonvolatile cluster state and is not related in any way to a cluster object notification port.

A batch update notification port is similar in functionality to a cluster object notification port but is strictly used for receiving event indications that pertain to changes made to the cluster registry through the ApiExecuteBatch method. There are no event filters, context values, or state sequence numbers associated with a batch update notification port.

A ClusAPI Protocol client can perform the following management operations on a cluster registry batch update notification port:

  • Create: Create a batch update notification port for receiving information about changes in the cluster registry. For more information, see section 3.1.4.2.113.

  • Close: Close the notification port. For more information, see section 3.1.4.2.115.

  • Retrieve an event: Get the first event at the head of the queue. For more information, see section 3.1.4.2.114.
