Replication Agent is a component of a replication system that moves primary database transactions from DB2 through Replication Server to replicate databases.
Replication Agent fits into the generic replication system, illustrated in Figure 1-4, with the following differences:
With Replication Agent, the primary database is DB2, which runs as a subsystem in MVS. The database logs are DB2 logs.
Replication Agent provides a log extract, called Replication Extract, that reads the DB2 logs and retrieves the relevant DB2 active and archive log entries for tables marked for replication.
The LTMAPI send function receives the data marked for replication from Replication Extract and LTMOC transfers this data to Replication Server using the TCP/IP communications protocol.
Replication Server then applies the changes to the replicate databases.
