Hi If I have 4 database with 4-way Oracle Streams setup means all changes on one server are pushed to all other 3 servers and vice versa. If I loose one Database due to Disk problem and have no backup. If I will create the new Database on the Server where I had the disk issue, then how I can re-instantiate all DB server so that they all can talk to the newly created database.
