SQL Server

There are various mechanisms in NCache to keep the data synced across the cache, among them is the SQL Server Dependency. This can be used in scenarios where the user wants to keep the data synchronized with the SQL database as discussed below.

Configure SQL Dependency on SQL Server

SQL Dependency can be used in two modes, i.e., the Default mode or Custom mode. In the Default mode, the SQL Dependency creates a default service and queue at run time for the SQL server. In the case of Custom mode, a customer-defined SQL Dependency service and queue will be created and used by NCache. In this case, NCache will connect with the pre-created service and queue with the following naming convention:

  • NCacheDBService-[IP-Address]

  • NCacheDBQueue-[IP-Address]

You can change the SQL Dependency service and queue name prefix by specifying it against the NCacheServer.NCacheDBServicekey and NCacheServer.NCacheDBQueue key.

<add key="NCacheServer.NCacheSQLNotificationService" value="NCacheSQLService"/>

<add key="NCacheServer.NCacheSQLNotificationQueue" value="NCacheSQLQueue"/>
