Logical replication using Dbvisit Replicate is configured using a setup wizard. The setup wizard does not make any database changes, instead it creates a set of configuration scripts that can be inspected before executing to give full visibility of database changes.
...
This configuration will take about 15 minutes.
| Note |
|---|
The database orcl on both the source and target server should be started and available. They are needed by Please ensure the following Pre-requisites checks have been tested. Otherwise the replication will not function. |
Starting the dbvrep setup wizard

...
To check if the database is running run the following command (on both source and target)
| No Format |

$ ps -ef | grep pmon

If the ora_pmon_orcl process is running, that is a good indication that the Oracle database is running.

This wizard configures Dbvisit Replicate.
The setup wizard creates configuration scripts, which need to be run after the wizard ends. No changes to the databases are made before that.
The progress is saved every time a list of databases, replications, etc. is shown. It will be re-read if wizard is restarted and the same DDC name and script path is selected.
