The cache manager service in WebSphere Portal is used to cache a wide variety of types of information in memory. These caches are somewhat similar to the registries maintained by the registry service, as each type of information gets its own cache. The key differences are:

The information stored in the cache manager service’s caches tends to be more dynamic than the information stored in the registry service’s registries.

The caches used by the cache manager service are limited in size, and entries will be discarded when the caches become full. The registries used by the registry service are not size-limited; they contain all entries of the specific data type.

Expiry times are managed individually for each entry in the cache, managed by the cache manager service. In contrast, when the reload time is reached for a registry, the entire contents of that registry are reloaded.

Each cache has several configurable options. A full discussion of these options, along with a list of the caches in WebSphere Portal V6.1, is given in chapter 2. Table 5 lists the changes which we made to the cache manager service configuration file. Size values are specified in “number of objects” and lifetime values are specified in “seconds”.
