Far Sync is a lightweight Oracle instance that has only a control file, spfile, password file and standby log files, there are no database files or online redo logs Oracle Far Sync provides the ability to perform a zero data loss failover to a remote standby database without requiring a second standby database or complex operation. Far Sync enables this by deploying a Far Sync inst...
