Multimaster Replication allows multiple sites (called Master Sites), acting as equal peers, to manage groups of replicated database objects.
To set up multimaster replication:
  1. Click Setup Master Sites... to launch a wizard that helps you set up a multimaster replication environment.

  2. Click Create Master Group... to create a master group that will manage the replicated objects. Upon completion, the new group will appear in the navigator, and a request will be submitted to start the replication process.

  3. From the navigator, select the master group you just created. Multimaster replication is running if the master group status is Running.
