[Version 5.0.2 and later]Cache instance collection

Use this page to configure and manage cache instances.

To view this administrative console page, click Resources > Cache Instances > New.

Scope
Use the Scope to limit the availability of the cache instance to a particular cell, node, or server. Select the Cell scope to view and configure cache instances that are available to all servers within the cell. Specify the Node scope to view and configure cache instances that are available to all servers with the particular node. Specify the Server scope to view and configure cache instances that are available only on the specific server.
Name
Specifies the required display name for the resource.
JNDI name
Specifies the Java Naming and Directory Interface (JNDI) name for the resource. Use this name when looking up a reference to this cache instance. The returned object is of the DistributedMap type.
Description
Specifies a description for the resource. This field is optional.
Category
Specifies a category string to classify or group the resource. This field is optional.
Cache Size
Specifies a positive integer for the maximum number of entries that the cache holds.

The range is 100 to 200,000.

Enable Disk Offload
Selecting this option enables disk offloading.

By default, dynamic cache only maintains the number of entries configured in memory. If new entries are created while the cache is full, the priorities configured for each cache entry, along with a least recently used (LRU) algorithm, are used to remove entries from the cache. As an alternative, you can configure disk offload to copy entries onto the file system for access at a later time. The location to copy the entries is configurable.
