NCache 3.8 Service Pack 4 (SP4) contains important fixes which are important for production environments. It is a recommended upgrade for all NCache 3.8 users.

Enhancements and New Additions

Following are some enhancements made in this release:

  1. String sharing between Java and .NET (vice versa):
  2. You can share string values between .NET and Java applications.

  3. SQL Cache Dependency Custom Queue/Notification Service:
  4. SQL Cache dependency architecture has been enhanced to support custom queues and notification services that does not require extra user permissions like “create queue” and “create service”. NCache now allows you to choose either default mode (with default SQL notification and queue service) or custom mode where you can specify your own queue and notification service. The service name format should be "NCacheSQLService-[ip-address]" and "NCacheSQLQueue-[ip-address]" where the IP-Address will be of machine on which NCache service process will be running. You can specify this setting in service configuration file “NCache/bin/service/Alachisoft.NCache.Service.exe.config”.
    <add key="NCacheServer.NCacheSQLNotificationService" value="NCacheSQLService"/>
