Setting Up Frequent Disk Cache for LiveSync Replication

Frequent disk cache for LiveSync replication can be setup to facilitate faster and efficient synchronization of data between the production and standby CommServe hosts, by modifying the Failover Transaction Log schedule, which is automatically created when the LiveSync operation is enabled.

Result

A continuous replication job will be started and can viewed in the Job Controller.

Additional Information

  • Whenever a production failover to a standby host is initiated, the failover process checks to see whether an active replication job is in progress, and if it is in progress, waits for it to finish before performing the failover.

    After the failover, a new replication job will be automatically started from the new node.

  • If necessary you can configure the replication job. For more information, see Modifying the Settings for LiveSync Replication Job.
