Plan for Oracle

When planning to transfer data to Oracle, you should consider the databases and user information, such as database names, what data is stored, and the database space needed.

Before you begin:

The database names and users in this topic are suggested values and provide consistency throughout the documentation. Replace these values with values in environment.

  1. Review the different databases shown in the following table and replace these values with the values in environment; schema names must be different when the database is shared.

      WebSphere Portal can be configured to use a single shared database if different database users are chosen for each database listed below. On Oracle, a single database configuration can significantly reduce consumption of system resources by the database management system. Using separate table spaces for all databases listed below can improve scalability and performance.

      Application Database name Space required
      WebSphere Portal

      Used for the portal (at a minimum) or to hold all data. Stores information about user customization, such as pages, and user profile and login information.

        reldb

        commdb

        custdb

      		Depends on the number of users and portal objects, such as pages and portlets.
      Personalization,Web Content Manager

      Contains documents, personalization rules, personalization campaigns, and document library configuration information.

        jcrdb
      		Depends on the number and size of Personalization rules and campaigns, and the number and size of items and elements created in Web Content Manager.
      Feedback

      Contains the information that is logged by Web site for analysis of site activity and generating reports.

        fdbkdb
      		Depends on the amount of traffic to the site. The amount of data that is logged per login-enabled page can vary.
      LikeMinds

      Contains the recommendations to be displayed to users when their interactions with Web site have been analyzed and predictions generated.

        lmdb
      		Depends on the amount of traffic to the site.

  2. Review the tables and types of objects owned by each user.

      The architecture allows each of the following users to exist in the same database. All table spaces are approximately 2.8 GB by default. The size increases with the use of Java™ Content Repository. Table 2. Tables and objects owned by database users


      Application
      Database user placeholder
      Function
      WebSphere Portal

        releaseusr

        communityusr

        customizationusr

      		Core user who owns approximately 230 tables, used for WebSphere Portal core objects, which includes tables that store the user customizations made to pages.
      Java Content Repository

        jcr
      		Java Content Repository user who owns at least 1130 tables. The number could be higher depending on usage.
      Feedback

        feedback
      		Feedback user who owns approximately 50 tables used for logging site and personalization usage.
      LikeMinds

        likeminds
      		LikeMinds user who owns approximately 15 tables used to hold the Web site usage analysis routines and recommendation text.

Re: Planning for Oracle: wp7

"WebSphere Portal can be configured to use a single shared database if different database users are chosen for each database listed below." Single database vs. each database? This is confusing. Please review the documentation concerning transfer to Oracle on proper wording.
