Clear Cache
Clearing the cache is a critical administrative task for emptying distributed data and resetting the cache state without removing the cache configuration. NCache provides two primary methods to clear the cache contents: a GUI-based approach via the NCache Management Center and an automated approach using PowerShell. This process effectively removes all items from the specified cache, ensuring a fresh environment for testing or data synchronization.
Method 1: Clear Cache via NCache Management Center (GUI)
Launch the NCache Management Center by browsing to http://localhost:8251 or
<server-ip>:8251.In the left navigation bar, click on Local Caches or Clustered Caches based on the cache to be cleared. This opens a new page. It shows any existing local or clustered caches and additional details like Server and Server Platform.
Click on the "..." button against the cache name.
Click on Clear Contents from the options.
- A message will be displayed on the screen when clearing cache contents.
- On successful cache clear, a notification will confirm that the cache has been cleared.
Method 2: Clear Cache Using PowerShell
- The Clear Cache cmdlet enables the user to clear the cache by removing all items currently present. The following command clears the items present in the cache named demoCache forcefully.
Clear-Cache -Name demoCache -ForceClear
- The following command forcefully clears the cache and does not confirm with the user before clearing the cache.
Clear-Cache -Name demoCache -Force
- You can also clear JavaScript or CSS content from the cache by using the following command.
Clear-Cache -Name demoCache -ClearJSS
- To clear a specific cache in a cluster you can execute the following command.
Clear-Cache -Name demoCache -Server 20.200.20.11
- If the user has configured security the folloiwng comand will confirm from user wethere they want to to proceed using security credentials.
Clear-Cache -Name demoCache -Credentials(Get-Credential john_smith)
