The various replication components run independently of one another,
but rely on one another for information that each stores in the replication
control tables to communicate with one another.
- The administration tools
- The Replication Center or ASNCLP command-line program creates SQL scripts
that insert the initial information about registered sources, subscription
sets, and alert conditions in the control tables.
- The Capture program or triggers
- The Capture program and the Capture triggers update the control tables
to indicate the progress of replication and to coordinate the processing of
changes.
- The Apply program
- The Apply program updates the control tables to indicate the progress
of replication and to coordinate the processing of changes.
- The Replication Alert Monitor
- The Replication Alert Monitor reads the control tables that have been
updated by the Capture program, Apply program, and the Capture triggers to
understand any problems and progress at a server.
