External and Internal Commit Control

Replication Server does not support external commit control when Oracle is the replicate database.

Replication Server uses the rs_dsi_check_thread_lock function to check whether the current DSI executor thread is blocking another replicate database process. For example: 
'select count(*) as seq from DBA_BLOCKERS 
 where holding_session in (select sid from v$session 
 where audsid = userenv('SESSIONID'));'
