Create a Distributed Cache

This section will demonstrate how you can create a distributed cache through the NCache Management Center or Command Line Interface.

Create a Distributed Cache Using 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. This opens up the Clustered Caches page at <server-ip>:8251/ClusteredCaches/.

  • To create a new clustered cache, click on New.

Create Distributed Cache Web

  • From the In-Memory Store Type dropdown menu, select Distributed Cache and specify the name of your cache. Select JSON or Binary from the Serialization dropdown menu as per your requirement. Click Next.

Select serialization format web

  • Select the caching topology and any advanced options like Operation Timeout and Statistic Replication Interval. If you have selected the Partition-Replica Cache topology, you have to select a Replication Strategy, either Asynchronous or Synchronous. Click Next.

Select Caching Topology Web

  • Specify the Maximum Size of the cache, if required. You can also add cache nodes to the cluster by specifying the node IP address and clicking on the Add Node button. To add more nodes, click Add Node. Click Next once all the required nodes are added.
Warning

If the cache is already registered on that node, a notification is prompted.

Select Replication Strategy Web

  • Change the Cluster Port and Port Range if required. Enable pipelining for the cache if required by checking the Enable Pipelining checkbox. Set the batch interval for the duration after which the commands will be transmitted over the network in microseconds. Click Next.

Cache Size Clustered Cache Web

  • If you want to enable encryption and compression, check the Enable Encryption and Enable Compression checkboxes. If enabled, set the Providers and Key for encryption and Threshold Size for compression. Click Next.

Encryption and Compression Settings

  • Click Finish. The created cache will appear on the Clustered Caches page with the server nodes and their status and a success notification will be received in the notification panel.

Using Command Line Interface

You can also use PowerShell or Command Line Tools to manage distributed caches by using the NCache-supported Command Line Interface.

Create Cache

The New-Cache cmdlet enables the user to create a new cache on one or more server nodes.

This command creates a distributed cache named demoCache of PartitionReplica topology of size 1024MB on node 20.200.20.40.

New-Cache demoClusteredCache -Server 20.200.20.40 -Size 1024 -Topology PartitionReplica

Add Node to Cache

The Add-Node cmdlet enables the users to add a new server node to the existing clustered cache on the specified server. It also enables users to have multiple server nodes in a clustered cache.

This command adds a new node 20.200.20.39 to the cache named demoClusteredCache existing on server node 20.200.20.40, which already exists.

Add-Node -CacheName demoClusteredCache -ExistingServer 20.200.20.40 -NewServer 20.200.20.39

Start Cache

Once the cache is created, you need to start the clustered cache on all the server nodes so that operations can be performed on it. The Start-Cache cmdlet enables the user to start the registered cache and cache process on the specified nodes.

Perform this step on all server nodes.

Start-Cache -Name demoClusteredCache -Server 20.200.20.40
