Persistent Cache Interval

The NCache Distributed Cache with Persistence allows you to back up data to the Persistence Store. All write operations are first performed in-memory and then enqueued for replication to the backend store. The persistence thread is invoked at a configurable interval called Persistence Interval to store the queued operations asynchronously. You can configure Persistence Interval for your cache in the following ways.

Using the NCache Management Center

  • Launch the NCache Management Center 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 for which you need to configure the settings. Select the cache name, click on View Details.

Important

Ensure the cache is stopped before proceeding.

Cache View Details

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

  • Change the Persistence Interval in the tab.

Configure Persistence Settings NCache Management Center

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

  • Start the cache to resume operations.

Manually Editing NCache Configuration

You can manually edit the NCache configuration file as explained below:

Important

Ensure the cache is stopped before making any configuration changes.

  • Update the persistence interval for a cache in config.ncconf by specifying the persistence-interval in the <data-persistence> tag.
<data-persistence ...>
    <operation-setting persistence-interval="1000ms" persistence-retries="3" persistence-interval-longer="60sec"/>
</data-persistence>
  • Once changes are made, start the cache, and restart the NCache Service.
