Control schema objects created for a publication v7
After you add a publication database definition and publications, the following control schema objects are created in addition to your original publication tables and views:
- In the publication database, control schema objects are created to control and manage the Replication Server replication systems. How the control schema objects are organized under the actual, physical database schemas depends on the publication database server type, that is, whether it is Oracle, SQL Server, or Postgres.
- If the publication isn't a snapshot-only publication, that is, synchronization replication is permitted and synchronization replication is implemented using the trigger-based method, then three triggers and one shadow table are created for each publication table as part of the control schema.
- If the publication is using synchronization replication with the log-based method, then a single trigger is created for each publication table as part of the control schema.
Don't manually delete any of these database objects as the replication system control schema will become corrupted.
Removing publications and publication database definitions using the Replication Server console or CLI deletes the control schema objects.
Oracle control schema objects
The control schema objects created in the publication database user’s schema (that is, the control schema) are shown in the following output:

SQL Server control schema objects
Most of the control schema objects are created in schemas _edb_replicator_pub, _edb_replicator_sub, and _edb_scheduler. Additional control schema objects are created in the schema you chose in Step 5 of SQL Server publication database. The following examples assume the schema you chose is pubuser. The publication tables are dept and emp located in the edb schema.
The following query lists the control schema objects located in these schemas:

Note (For SQL Server 2012, 2014): The following database objects from the preceding list are no longer created as part of the control schema when the publication database is SQL Server 2012 or 2014:

SQL Server versions 2014 and 2012 support creation of sequence objects that can now perform the functionality previously provided by the preceding list of objects. The following are the sequence objects that are now used when the publication database is SQL Server 2012 or 2014:
1> USE edb; 2> GO Changed database context to 'edb'. 1> SELECT s.name + '.' + o.name "Object Name", o.type_desc "Object Type" 2> FROM sys.objects o, 3> sys.schemas s 4> WHERE s.name IN ('_edb_replicator_pub', '_edb_replicator_sub', 5> '_edb_scheduler', 'pubuser') 6> AND o.type IN ('SO') 7> AND o.schema_id = s.schema_id 8> ORDER BY 1, 2; 9> GO Object Name Object Type -------------------------------------------------- --------------------- _edb_replicator_pub.rrep_common_seq SEQUENCE_OBJECT _edb_replicator_pub.rrep_tx_seq SEQUENCE_OBJECT _edb_replicator_pub.rrep_txset_seq SEQUENCE_OBJECT (3 rows affected)

For non-snapshot-only publication tables, triggers are created that reside in the schema containing the publication tables as shown by the following:
1> USE edb; 2> GO Changed database context to 'edb'. 1> SELECT s.name + '.' + o.name "Trigger Name" 2> FROM sys.objects o, 3> sys.schemas s 4> WHERE s.name = 'edb' 5> AND o.type = 'TR' 6> AND o.name LIKE 'rr%' 7> AND o.schema_id = s.schema_id 8> ORDER BY 1; 9> GO Trigger Name -------------------------------------- edb.rrpd_edb_dept edb.rrpd_edb_emp edb.rrpi_edb_dept edb.rrpi_edb_emp edb.rrpu_edb_dept edb.rrpu_edb_emp (6 rows affected)
Finally, some jobs are created in the msdb database after the subscription is created as shown by the following:
1> USE msdb; 2> GO Changed database context to 'msdb'. 1> SELECT j.name "Job Name" 2> FROM msdb.dbo.sysjobs j, 3> primary.dbo.syslogins l 4> WHERE l.name = 'pubuser' 5> AND j.name LIKE 'rrep%' 6> AND j.owner_sid = l.sid 7> ORDER BY 1; 8> GO Job Name -------------------------------------- rrep_cleanup_job_edb rrep_txset_job_edb (2 rows affected)
Postgres control schema objects
The control schema objects are created in three schemas named _edb_replicator_pub, _edb_replicator_sub, and _edb_scheduler.
The control schema objects contained in _edb_replicator_pub are shown by the following:

If the log-based method of synchronization replication is used, the following triggers are created on the publication tables:
edb=# SELECT t.tgname AS "Trigger Name", c.relname AS "Table Name", edb-# f.funname AS "Trigger Function" edb-# FROM pg_trigger t, pg_function f, pg_class c edb-# WHERE tgname LIKE 'rrpt%' edb-# AND t.tgfoid = f.oid edb-# AND t.tgrelid = c.oid edb-# ORDER BY t.tgname; Trigger Name | Table Name | Trigger Function ---------------+------------+---------------------- rrpt_edb_dept | dept | capturetruncateevent rrpt_edb_emp | emp | capturetruncateevent (2 rows)
These triggers are used to support synchronization replication of the TRUNCATE command when using the log-based method.
