When you use an external RDBMS, you must create the MywebMethodsServer database components in your external RDBMS. When you choose the external RDBMS in the installer, the installer asks you to supply the database connection.

If you are clustering My webMethods Servers, create a single MywebMethodsServer database component for the cluster to share. If you are not clustering, create a separate MywebMethodsServer database component for each My webMethods Server.
