Ports

NCache uses TCP ports for communication. Default TCP port is 8250. These ports can be changed, if required, by changing the values of the registry key (TCP.PORT) written upon the installation of NCache.

This key can be found under the following path: HKEY_LOCAL_MACHINE/SOFTWARE/ALACHISOFT/NCACHE

Please note that NCache Web Manager application assumes the default port. Therefore, upon changing the values of this port, Local Cache/Cluster cannot be administered through NCache Web Manager application. However, NCache command line utilities and tools provide the option to address the Local Caches/Clusters on other ports.

Cluster Port and Port Range

Cluster ports are the ports at which NCache clusters start. You can also specify the port range so that if the current port is unavailable, the server will automatically pick the next available port in the range. You can change the default value of these ports. For installed caches (myReplicatedCache, myPartitionedCache), NCache looks for ports starting from 7800 onwards and allots the available ports to these caches in the available port range.

Using NCache Web Manager

  • Launch NCache Web Manager by browsing to http://localhost:8251 (Windows) or <server-ip>:8251 (Windows + 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.

CLuster Port Web

  • 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.

  • Change the Cluster Port and Port Range, as required.

CLuster Port Port Range Web

  • 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 port range through config.ncconf by specifying the cluster-port and port-range keys in the <cluster-connection-settings> tag:
<cluster-settings ...>
  <cluster-connection-settings cluster-port="7806" port-range="1" .../>
</cluster-settings>
  • Once changes are made, start the cache and restart NCache service.

Server Port

At the NCache Server Port, NCache Server starts and accepts different client connections. Default value of this port is 9800. You can change the default value through Service Configuration file as follows:

<add key="NCacheServer.Port" value="9800" />

This will change the value at Server side. This change must also be made in client.ncconf to make client aware of this change, as follows:

<ncache-server port="9800" .../>
