Materialization is the process of initially populating the replicate database with a copy of the data from the primary database. LTM for MVS requires that you set up and populate each replicate database so that it is in a state consistent with that of the primary database. Figure 2-2 shows the effects of materialization on replicate databases.

There are two types of materialization:
Rep Agent materialization
Rep Agent materialization is the process of populating a replicate database using the unload utilities and the dataHandler=LTMMAT Replication Agent configuration. This method requires you to manually activate your subscriptions after the replicate database is populated.
Automatic materialization
Automatic materialization is the process of populating a replicate database using Replication Server commands. After the replicate database is populated with a copy of the primary data, replication is active.
Replication Agent for DB2 does not support automatic materialization.
See the Replication Server Administration Guide for further information on materialization.
