WEB CONTENT MANAGEMENT CACHES

In the preceding chapter we described the specific values we modified for the Web Content Management (WCM) caches in our environments. This chapter describes the Web Content Management caches and the general parameters for those caches.

WCM Cache Instances

With WebSphere Portal V6.1, the WCM caches are managed via the WebSphere Application Server administrative console under Resources > Cache instances > Object cache instances.

services/cache/iwk/strategy – WCM Item caching

Default size: 2000, default lifetime: infinite, usage pattern: regular.

This cache stores internal WCM items. Any WCM item read from the database will first check this cache. WCM items cover Content, Workflow, Workflow Stages, Workflow actions, Taxonomies, Categories, Authoring Templates, Presentation Templates, Sites, Siteareas, and all Library Components. The cache entry will be updated or cleared when its corresponding WCM Item is updated or deleted.

W C M S U M M A R Y

services/cache/iwk/objectsummary – WCM Summary

Default size: 2000, default lifetime: infinite, usage pattern: regular.

This cache stores summaries of WCM Items. The summaries are used to display in lists in the authoring portlet or used internally in the WCM API to calculate WCM Item Document IDs used for Iterators. The cache entry will be cleared when a WCM Item is updated that will affect this summary.
