During the configuration of WebSphere Commerce Analyzer, the data mart is set up with pre-defined buffer pools, tables and tablepaces. This step is documented in the Configuring WebSphere Commerce Analyzer section of the WebSphere Commerce Additional Software Guide.
To change the buffer pools, tables and tablespaces of an existing data mart, you must use the tools in the DB2 Control Center. For more information, see your DB2 product information and search on buffer pools, tables or tablespaces. The DB2 information center is located at the following URL:

To recreate your data mart you can configure WebSphere Commerce Analyzer again, as described in Configuring WebSphere Commerce Analyzer section of the WebSphere Commerce Additional Software Guide.
