With the enhanced replication definition, you can request replication definition changes directly at the primary database using the alter replication definition, alter applied replication definition, or alter request function replication definition commands, while making changes to the database schema.
You can:
Issue a replication definition command directly from a primary database.
Use an alter replication definition command to instruct Replication Server to suspend the target DSIs after Replication Server applies all data for the old replication definition version at the target database. This provides a window for you to alter the target schema and alter customized function strings before the data for the new replication definition version arrives.
Verify that Replication Server can execute a replication definition request successfully by executing the request without changing any data.
Drop columns from a replication definition using alter replication definition.
Instruct Replication Server to skip a failed replication definition request sent by a Replication Agent. When a replication definition command fails at the primary Replication Server, Replication Agent shuts down. If you restart Replication Agent, the failed command executes again unless Replication Server skips the command.
