Connection Retries

Nodes participating in a cluster are connected with each other through TCP connections which may break up due to network failure. In that case, a client node tries to re-establish the connection. It goes through all the servers in the list once and if none is available, it sleeps for Retry Interval seconds and then scans the list again. This is done Connection Retries times. In other words, the value of Connection Retries specifies how many times the node should try to restore the connection.

Note

This feature is also available in NCache Professional.

Connection Retries can be changed 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 to configure.

• 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 Cluster Settings in the left bar.

• Set the Connection Retries as per your requirement.

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

Manually Editing NCache Configuration

Important

Ensure the cache stops before making any configuration changes.

• Specify connection retries count through config.ncconf by specifying the connection-retries key in the <cluster-connection-settings> tag:

<cluster-settings ...>
  <cluster-connection-settings connection-retries="2" .../>
</cluster-settings>

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