How does one set up multi-master replication?
Steps for setting up multi-master replication: • Run ?/rdbms/admin/catrep.sql as user SYS AS SYSDBA (or INTERNAL). • The SID for each database must be unique. • INIT.ORA parameters JOB_QUEUE_PROCESSES and JOB_QUEUE_INTERVAL need to be set if you want to schedule replication automatically. • GLOBAL_NAMES must be set to TRUE if you are using the Oracle Replication Manager GUI. • One can use the OEM Replication Manager to configure replication or by issuing PL/SQL API calls. Sample scripts are available here.
