To temporarily suspend replication of a marked sequence, you can use the pdb_setrepseq command. When you are ready to resume replication of the marked sequence, use pdb_setrepseq again to reenable replication.
To replicate updates of a sequence in the primary database, the sequence must be marked for replication and replication must be enabled for that sequence.
Marking a sequence for replication is separate from enabling replication for the sequence.
