What is Data instantiation
Before data replication can start, the target database must have a copy of the database objects that are going to be replicated. It is also necessary that the data for the objects to be replicated are completely in sync at the point at which the replication starts. This is done with the Oracle SCN. By using the Oracle SCN it is guaranteed that no transactions are lost during the replication setup.
...
- Everything before the SCN must be copied manually. This is called Data Instantiation and is done in this example through Oracle DataPump.
- Everything after the SCN is replicated by the replication tool (in this case Dbvisit Replicate)
Running DataPump
1. On the target server (dbv02), ensure that the OE schema is clean. Run the following script to ensure that there are no OE objects. If there are then the DataPump script will fail.
...
3. On the source server (dbv01) start the APPLY.sh script. This script will take approximately 25 minutes to complete.
