How Replication Suspension Works

At times it may be necessary to suspend updates on a Replica machine in order to perform system maintenance or some other form of processing that does not modify the replicated data there. It is not desirable to stop replication since this requires a resynchronization afterward.

The replication suspension feature makes this possible. Replication may be suspended either manually or on a scheduled basis. During the suspension period, all changes are spooled on the Master or on the Replica located upstream of the suspended Replica. In other words, changes continue to be recorded for update on the suspended Replica, but are not actually transferred until replication is resumed. After replication resumes, the accumulated changes are transferred and applied without the need to perform a resynchronization of the data.

To suspend replication, choose Tools, Suspend Replication from the Manager menu.
