Add-BackingSource
Note
This feature is only available in NCache Enterprise Edition.
Add-BackingSource cmdlet enables the user to configure backing source
(read-through, write-through) providers for the specified cache. It configures
backing source with batching and re-queue options.
Important
Make sure that the cache has been stopped before proceeding to execute this cmdlet.
Add-BackingSource –AssemblyPath -CacheName –Class -DependentAssemblyPath -ProviderName [-BatchInterval] [-DefaultProvider] [-isBatching] [-NoDeploy] [-NoLogo] [-OperationDelay] [-OperationEvictionRatio] [-OperationPerSecond] [-OperationQueueLimit] [-Parameters] [-Password] [-Port] [-ReadThru] [-Server] [-UserId] [-WriteThru]
These properties are explained in detail in the Properties section.
Examples
- The following command configures read-through provider for demoCache.
Add-BackingSource -CacheName demoCache -AssemblyPath C:\ReadThru.dll -Class ReadThru.Reader -ProviderName MyReader -ReadThru
- The following command configures write-through provider for demoCache.
Add-BackingSource demoCache -AssemblyPath C:\WriteThru.dll -Class WriteThru.Writer -ProviderName MyWriter -WriteThru
- The following command configures write-through provider with batching enabled, for demoCache that exists on server 20.200.20.11.
Add-BackingSource -CacheName demoCache -AssemblyPath C:\Provider.dll -Class WriteThrough.Writer -ProviderName MyWriter -WriteThru -Server 20.200.20.11 -isBatching
- The following command configures write-through provider with batching
enabled, OperationDelay 10ms, BatchInterval 5s, OperationPerSecond
500, OperationQueueLimit 3000, OperationEvictionRatio 10%, Parameters
