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

Cluster Port

Cluster ports are the ports at which NCache clusters start. You can change the default value of these ports from NCache Manager. For installed caches (myReplicatedCache, myPartitionedCache), NCache looks for ports starting from 7800 onwards and allot the available ports to these caches in the available port range.

Port of a cluster can be changed in the following ways:

Using NCache Manager

  • Click on the cache name in Cache Explorer to open cache settings.

  • Go to Cluster Settings tab.

  • Change the Cluster Port, if required.

  • Right click on the cache name in Cache Explorer and select Apply Configuration option.

Manually Editing NCache Configuration

Important

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

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

Port Range

Sets the port range for each node in the cluster. If the current port is unavailable, then the server will automatically pick the next available port in the pool. Port Range of a cluster can be changed in the following two ways:

Using NCache Manager

  • Click on the cache name in Cache Explorer to open cache settings.

  • Go to Cluster Settings tab.

  • Change the Port Range.

  • Right click on the cache name in Cache Explorer and select Apply Configuration option.

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 port-range key 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" .../>
