Replication of Databases for Oracle

You can use replication to perform incremental replication from a backup of a Oracle database to a synced copy of the Oracle database. The replication operation continuously applies changes from the source database backups since the last sync point.

The replication feature includes the following capabilities:

  • Automatically initiates replication after a log backup is completed on the source database.

  • Minimizes the impact on production systems' CPU and I/O by using the backup data for replication. This method avoids the need to read the source database again for replication.

  • Copies the backup data to remote disaster recovery (DR) sites with deduplication to minimize the wide area network (WAN) traffic. Replication then runs at the DR site.

  • Initiates replication after the auxiliary copy completes, when you use a copy precedence for replication.
