Registry Service

The portal Registry Service loads and caches a small number of objects that are regularly accessed in the engine. This improves performance. However the trade off is that the cached objects can be stale compared to their database counterparts. This applies particularly in a cluster environment.

If the age of those objects causes a problem, try reducing the refresh rate for the respective entities.

In the WebSphere® Integrated Solutions Console, the portal Registry Service is listed as WP RegistryService.

The following list describes the Registry Service properties:

default.interval = (1800): The default interval for refreshing a bucket. The amount is specified in seconds, for example default.interval = 1800.
bucket.<bucket-name>.class: The type of class that the bucket with the given name is caching.
bucket.<bucket-name>.reload [optional = true]: This property controls whether or not the bucket with the given name is reloaded in frequent intervals.
bucket.<bucket-name>.interval = (default.interval): The length of the reload interval for the bucket with the given name. If no value is set, the default.interval setting is used.
bucket.<bucket-name>.sorted [optional = false]: This property controls whether or not the bucket with the given name needs to keep the cached objects in a sorted order. The sorting order is determined by the objects themselves.

The bucket names are described in the following:

theme: The theme bucket is used to cache the database representation of all themes stored in the database.
language: The language bucket is used to cache the database representation of all languages that are stored in the database.
skin: The skin bucket is used to cache the database representation of all skins stored in the database.
language: The language bucket is used to cache the database representation of all languages stored in the database.
client: The client bucket is used to cache the database representation of all clients stored in the database.
markup: The markup bucket is used to cache the database representation of all markups stored in the database.
