There are procedures you must follow to resynchronize databases in different scenarios. After completing these procedures, the primary and replicate databases are transactionally consistent.
To execute these procedures, you must:
Be a replication system administrator
Have an existing replication environment that is running successfully
Have methods and processes available to copy data from the primary database to the replicate database
For commands and syntax for:
Replication Agent for Oracle – see the Replication Agent Reference Manual.
Replication Server – see the Replication Server Reference Manual.
