A Mirror Activator system consists of a special variant of the Sybase transaction replication system, which is integrated with a disk replication system (provided by another vendor).
Figure 1-1 shows a typical Mirror Activator system configuration. Arrows illustrate the flow of mirrored log device data and replicated transactions during normal Mirror Activator system operation, that is, while replicating transactions from the primary database to the standby database.

The disk replication system is the Mirror Activator system
component that moves log data from the primary site to the standby
site. Components of the disk replication system reside at both primary
and standby sites.
