Bi-directional replication question..

Question

I configured database A & database B for two-way replication.
Basically, I configured from A to B without any problem, before runs "Start_Capture", I export & import the tables with rows=n.
Question is, Now I need to configure from B to A. Do I need to export from B and import to A with rows=n before running "Start_Capture" on B? or just simply runs "Start_Capture" on B?? thanks..

Answer 1

You can do this on B for instantiating table on A
DECLARE iscn NUMBER;
BEGIN
iscn := DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER();
DBMS_APPLY_ADM.SET_TABLE_INSTANTIATION_SCN@A(
source_object_name => 'schema.table',
source_database_name => 'B',
instantiation_scn => iscn);
END;
BEGIN
DBMS_CAPTURE_ADM.PREPARE_TABLE_INSTANTIATION(table_name => 'schema.table');
END;
