You use the Control Center to define sources and targets for replication, as well as to set the schedule for updating the targets, to specify the enhancements to the target data, and to define any triggers that kick off replication. The administration tasks described in this chapter set up the control information that both the Capture and Apply programs use to capture updated data and then replicate it to the target tables, in the proper format, and at the appropriate interval.
Replication administration has two major tasks: defining replication sources and defining replication targets (subscriptions). Replication sources are DB2 tables, views, or nicknames used as source for copying data to a target table. Replication subscriptions are the specifications for one or more target tables and their location, structure, and timing schedule, as well as any SQL enhancements that are necessary. Other replication tasks include maintaining the replication sources and subscriptions, and cloning them to other servers.
