Attaching a New Fragment to a Replicated Table

You can attach a new fragment to a replication table while replication is active.

About this task

Enterprise Replication cannot automatically set alter mode for this operation because of an SQL restriction that requires attaching a fragment to be performed in multiple steps.

Procedure

To attach a new fragment to a replicated table:

Set alter mode on the replicate by running the cdr alter on command.
Drop the replication key of the table.
Attach the new fragment.
Re-create the replication key.
Unset alter mode by running the cdr alter off command.
