Rules for setting properties for a Replication-enabled database
From the management console, you can configure various properties for a database enabled for Replication. The options you have in the console for configuring these Replication-related properties depend upon the following rules:
For a database notenabled for Replication:
If the Replication property file does not exist, no Replication links are available.
If the Replication property file does exist but is empty, a Server (create new) link and an Agent (create new) link appear.
You can configure transition only when one of these groups exists.
If the Replication property file does exist and is not empty, then all groups defined in the property file appear.
For a database enabled for Replication:
If the Replication property file does not exist, Replication-related links still appear. However, you can create only the group for which the database is enabled. In other words, you can create the Server group for source-enabled databases and the Agent group for target-enabled databases.
If the Replication property file does exist, only the groups that are applicable to the database enablement appear. For source enablement, Server, ctrl-agents, and transition appear. For target enablement, Agent and transition appear.
If the Transition group database-role is set to reverse, you either see the existing group for the reverse role or are allowed to create a new group for the reverse role.
If you specify Alternate buffer pool blocks for a Replication target database, the property setting is ignored.
