Use the mqsi_setupdatabase command to set up an Oracle database on UNIX systems. Do not run this command for any other supported database.
This command sets up the required database links for the Oracle database that is used within your WebSphere Message Broker environment. You must run the command for both broker and user databases. The command works for a remote database in the same way that it does for a local database.
Run this command after you have installed the Oracle database manager but before you create the broker database. If necessary, though, you can run the command before you install the Oracle database manager as long as you specify the intended database installation directory correctly.
