Create New Local Pub/Sub Messaging Cache

A local pub/sub messaging cache can be created in the following ways

Prerequisite

Make sure NCache Service is started. If it is not started, do the following:

• Windows Environment
• Linux Environment

In PowerShell, execute the following command:

Start-Service -Name NCacheSvc

For .NET Core, make sure that you run the NCache service as an administrator. Here are the steps to do so:

• Open Services window and look for NCache in the list.
• Right click on NCacheSvc from the list and choose Properties.
• Go to the Log On tab and click on the Browse button.
• In the object name field, type Administrator and click on the Check Names button.
• It will pick the appropriate Administrator, then click OK.
• Now, set a Password and click OK.
• Right click on the NCache service and choose the Restart option. Now your service will start running as administrator.

Using NCache Web Manager

• Launch NCache Web Manager by browsing to http://localhost:8251 or <server-ip>:8251 on Windows and Linux.

• In the left navigation bar, click on Local Caches. This opens up the Local Caches page at <server-ip>:8251/LocalCaches/. The page shows any existing local caches on your machine and additional details like Server and Server Platform.

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

• Specify the Server Node IP / Name and click Next.

• Specify the In-Memory Store Type as Pub/Sub Messaging from the dropdown menu. Afterwards, specify the Name, Isolation Level, and Serialization (Binary or JSON) of your cache. Click Next.

Warning

If a cache already exists against the Name specified, you are prompted with an error message.

Note

It is recommended that you use JSON serialization if you are using ASP.NET 5.0 and above. For more details click here.

• Change the cache size if required and click Next.

• 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.

• In Advanced Options page, you can configure the following settings:

  • Eviction is enabled by default. You can configure the Eviction Policy accordingly. If you want to disable eviction, uncheck the check box Enable Eviction.

  • You can also change the Eviction percentage; items will be evicted from the cache using this percentage value if eviction is enabled.

  • You can change the Clean interval value. Default is 15 seconds.

  • This cache can be started automatically upon the completion of this process if you have checked the Start this cache on Finish checkbox on this dialog box.

  • You can make the cache to start automatically after service restart by checking the checkbox Auto start this cache on service startup.

• Click Finish. The created cache will appear on the Local Caches page, and a success notification will be received in the notification panel.

Using PowerShell

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

This command creates a cache called myCache of Local topology with Size of 1024MB and InMemoryStoreType specified as PubSubMessaging on the node 20.200.20.47

New-Cache myCache -Topology Local -InMemoryStoreType PubSubMessaging -Server 20.200.20.47 -Size 1024
