InfoCenter Home > 3.5: Switching administrative databasesSuppose you want to switch from one supported database brand to another, for use as the WebSphere administrative database. Originally, the WebSphere Application Server installation program prompted you to enter information about the database configuration. This article provides instructions for switching to a different database brand without needing to run the WebSphere Application Server installation program again. Basically, you need to preserve the administrative configurations as stored in the current database, switch the administrative server settings to point to the new database, then import the administrative configurations into the new database. Follow these instructions:
Besides checking that the tables and data were correctly imported to the new database, performing the last two steps provides verification that the procedure was successful. If the administrative database settings were not modified successfully, the import would fail with SQL errors related to creating tables and data that already exist. (The import would be attempting to write to the former database, from which it exported the data, instead of to the new database). Similarly, attempts to start the administrative server would fail with SQL-related exceptions. |
