Add-StartupLoader - Cache Loader
This enables the users to configure startup cache loader for the cache which loads the configured datasets from source to the cache whenever the cache starts. It also allows the user to configure cache refresher that refreshes the pre-loaded data after a specified time interval.
Note
This feature is only available in NCache Enterprise.
Note
Please note that when using the NCache .NET Edition, you will require .dll libraries instead of .jar assemblies for this cache loader cmdlet.

Examples of Add-StartupLoader - Cache Loader
- This command configures a startup cache loader for a cache named demoCache. The assemblies to be deployed are placed at the specified path and the default port 8250.
Add-StartupLoader –CacheName demoCache –AssemblyPath C:\Loader.jar -Class StartupLoader.Loader
- This command configures a startup loader for a cache named demoCache. The assemblies to be deployed are placed at the specified path on the server node 20.200.20.11.
Add-StartupLoader -CacheName demoCache –AssemblyPath C:\Loader.jar -Class StartupLoader.Loader –Server 20.200.20.11
- This command configures a cache refresher for demoCache on server 20.200.20.11 with a refresh interval set to 1200 seconds.
Add-StartupLoader -CacheName demoCache -AssemblyPath C:\Loader.jar -Class StartupLoader.Loader -Server 20.200.20.11 - RefreshInterval 1200
- This command configures a cache refresher for demoCache on server 20.200.20.11 with poll-based refreshing enabled.
Add-StartupLoader -CacheName demoCache -AssemblyPath C:\Loader.jar -Class StartupLoader.Loader -Server 20.200.20.11 -PollForDatasetsToRefresh
