Configuring Data Expiration

Clean interval is the periodic interval after which the expired items are removed from the cache. By default, expiration Clean-Up interval is 15 seconds. However, it is changeable by the following ways:

Using NCache Web Manager

• Launch NCache Web Manager by browsing to http://localhost:8251 or <server-ip>:8251 on Windows and Linux.

• In the left navigation bar, click on Clustered Caches or Local Caches, based on the cache to configure.

Important

Make sure the cache is stopped before proceeding.

• Against the cache name, click on View Details.

• This opens up the detailed configuration page for the cache. Go to the Advanced Settings tab and click on Expiration Defaults in the left bar.

• Change the Clean Interval as per your requirement. Default is 15 seconds.

• You can choose any default expiration policy, and change its expiration time accordingly.

• Click on Save Changes to apply this configuration to the cache.

• Start the cache to resume operations.

Manually Editing NCache Configuration

Important

Make sure the cache is stopped before making any configuration changes.

• Specify cleanup interval through config.ncconf by specifying the <cleanup> tag in the <cache-settings> tag:

<cache-settings ... >
    <cleanup interval="15sec"/>
</cache-settings>

• Once changes are made, start the cache and restart NCache service.
