Plan for Oracle RAC

Plan for Oracle RAC

Overview
The database names and users in this topic are suggested values only. Replace values with values in for environment.
The default tablespace size for Oracle RAC may need to be set to 1024MB with autoextend turned on for database transfer to be successful.
WebSphere Portal can be configured to use a single shared database if different database users are chosen for each database listed below. 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 Notes 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.

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.
