If you are planning to implement Access Manager session failover, these components are required:
Web container to run Access Manager: Sun Java System Web Server, Sun Java System Application Server, IBM WebSphere Application Server, or BEA WebLogic.
Sun Java System Directory Server. All Access Manager instances must access the same Directory Server.
Sun Java System Message Queue. The Message Queue broker cluster manages the session messages between Access Manager instances and the session store database.
Berkeley DB by Sleepycat Software, Inc. (http://www.sleepycat.com/) is the default session store database. Use the version that is distributed with the Sun Java Enterprise System 2005Q4 release.
Access Manager session failover is supported on the following platforms:
SolarisTM OS, SPARC® based systems, versions 8, 9, and 10
SolarisTM OS on x86 platforms, versions 9 and 10
Red HatTM Linux, Advanced Server and Enterprise Server
For the latest information about the supported versions of these platforms and components, see the Sun Java System Access Manager 7 2005Q4 Release Notes.
