04 - Start the Replication

The pre-requisites have been completed. The replication can now be started.

1. On the source server, as oracle, in the $HOME/dbvrep_XE directory, start the MINE process.

cd ~oracle/dbvrep_XE/

3. On the source server, as oracle, in the $HOME/dbvrep_XE directory, execute the start-console.sh script to start the Replication console and view the replication.

./start-console.sh

The message "initialization NOT yet complete" is shown during the start of the replication process. This process involves Dbvisit Replicate replicating its own internal tables before replicating user tables. To show the internal tables being replicated type the command list progress all at the dbvrep> prompt
No tables are shown yet. The replicated tables will only be shown once DML is run against these tables.
The cls command will clear the screen.

Replication's a bit boring without anything happening, so let's use SwingBench to generate some activity in the source database and see what happens.
