Dbvisit Replicate creates a user (also called a schema) with a small repository in the source and target database to keep track of the replication. 

The database grants and privileges required by Dbvisit Replicate are generated automatically by running the setup wizard. It generates all the necessary scripts that create a new database users and grant all the privileges needed. This means it is very easy to review what actual privileges are necessary prior to actually executing the scripts and issuing the privileges.
