Release Notes NCache 3.6.2 (Service Pack 3)

Thursday, April 21, 2010

Introduction

NCache 3.6.2 (SP3) contains important fixes and enhancements that have been reported by customers. The most important and demanded feature added in this release is the support of Java session caching for J2EE platforms. Now, you can easily use NCache as a session store for your Java applications without making any code change. You only need to add a Java session filter in your web.xml file.

Those using NCache 3.6.x version can upgrade without re-building/re-compiling the application.

Enhancements and New Additions

Following are some enhancements made in this release:

  1. Java Session Support for WebLogic (no-code change required):
  2. NCache Java Session Provider is supported for WebLogic and can be used on any platform of J2EE (web servers), if underlying platform (web server) follows the Java Servlet 2.3 (or later) specification. Java Sessions are supported on both Linux and Windows platforms.

  3. Java Session Support for JBoss (no-code change required):
  4. NCache Java Session Provider is supported for JBoss on both Linux and Windows platforms.

  5. Java Session Support for WebSphere (no-code change required):
  6. NCache Java Session Provider is supported for WebSphere on both Linux and Windows platforms.

  7. Java Session Support for ApacheTomcat (no-code change required):
  8. NCache Java Session Provider is supported for Apache-Tomcat on both Linux and Windows platforms.

  9. NCache support for Server GC:
  10. There are two flavors of Garbage Collector based on server operating system and workstation called “Server GC” and “Workstation” respectively. Unless it is specified .NET framework uses workstation GC by default even it is running under server operating system. Now, NCache allows you to specify GC mode depending on your operating system. Server GC is designed for maximum throughput, and scales with very high performance. NCache is now by default configured to use Server GC instead of Workstation GC. You can change this mode from Alachisoft.NCache.Service.exe.config:

    <add key="NCacheServer.EnableForcedGC" value="true"/>
    <add key="NCacheServer.ForcedGCThreshold" value="80"/>
