3.2.1 Planning and considerations WebSphere Portal V6 provides new options to address scalability and redundancy in your enterprise deployments. If you choose to transfer to an external database, we recommend that you do so before you add a large amount of content and preferably during the installation and configuration process. Figure 3-3 shows some points to consider before you transfer you data to a database of enterprise scale.

For the success of your deployment, it is critical that the hardware and software that will be used to house the portal database(s) be not only highly optimized but resilient. Before you begin the database transfer process, review the prerequisites discussed below. System requirements It is important to conduct a preliminary review of the hardware and software of your system in both the new and existing database infrastructures to ensure they meet the supported levels for WebSphere Portal Server. The InfoCenter is routinely updated with specific versions and recommended compatible levels of configuration. If your are considering an upgrade to your database implementation, we advise you to refer to 3.1.1, "How do I prepare my system for installation" on page 56 before attempting an upgrade of your environment. Performance and availability WebSphere Portal Server provides you with the option of installing the database server on the same server that the WebSphere Portal Server will be housed; however, if performance is of utmost importance for your portal application(s), we recommend that you provide a separate physical database server for your RDBMS. Performance tools should be utilized continuously to monitor the state of the database server(s) and the databases themselves, with mechanisms instituted to tune the entities as needed. For additional information about planning for your database infrastructure, refer to 2.7, "Database considerations" on page 46. 66 IBM WebSphere Portal V6 Self Help Guide
