Support for Oracle sequence replication is supported only for replication to Oracle. No support is provided for replicating a sequence value to a non-Oracle replicate database.
Replication Agent supports replication of sequences in the primary database. To replicate a sequence invoked in a primary database, the sequence must be marked for replication, and replication must be enabled for that sequence. This is analogous to marking and enabling replication for tables.
Oracle does not log information every time a sequence is incremented. Sequence replication occurs when the Replication Agent captures the system table updates that occur when the sequence's cache is refreshed. Therefore, the sequence value replicated when a sequence is marked for replication is the “next” sequence value to be used when the current cache expires. The result is that not every individual increment of a sequence is replicated, but the replicate site always has a value greater than the primary site's currently available cached values.
To temporarily suspend replication of a marked sequence, you can disable replication for the sequence.
