You must initialize the primary database using the Mirror Replication Agent pdb_init command. Initializing the primary database does the following:
Verifies that the primary database configuration is correct for the Mirror Activator system
Marks the primary database for replication (equivalent to executing sp_reptostandby in the primary database)
After you initialize the primary database, you must
not allow any DDL operations in the primary database before it is
quiesced (the next setup task).
Initializing the primary database
Log in to the Mirror Replication Agent administration port.
WARNING! Do not use the move_truncpt option of the pdb_init command when you initialize the primary database. If you do not preserve the secondary truncation point in the primary database, you must rematerialize the standby database before you resume replication to prevent data loss.
Initialize the primary database:
pdb_init
