To temporarily suspend replication of a sequence, you can use the pdb_setrepseq command to disable replication for the marked sequence. When you are ready to resume replication of the marked sequence, you can use the pdb_setrepseq command to enable replication.
No sequences are marked by default for 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. See “Marking a sequence for replication”.
