All agents in the Policy Agent 2.2 release are compatible with Access Manager 7 and Access Manager 7.1. Compatibility applies to both of the available modes of Access Manager: Realm Mode and Legacy Mode.
Install the latest Access Manager patches to ensure that all enhancements and fixes are applied. For an example of Access Manager patches that can be installed, see the compatibility information discussed in Sun Java System Access Manager Policy Agent 2.2 Release Notes.
All agents in Policy Agent 2.2 are also compatible with Access Manager 6.3 Patch 1 or greater. However, certain limitations apply. For more information, see J2EE Agent Backward Compatibility With Access Manager 6.3.
Domain Administration Server (DAS) is an integral concept of Sun Java System Application Server 8.1. Installing the J2EE agent on Sun Java System Application Server 8.1 while not understanding the DAS concept can lead to complications. The following cautionary note describes one potential complication that can arise.
Once a J2EE agent is installed for a specific domain, the J2EE agent binaries cannot be used on that same host for a different Sun Java System Application Server 8.1 domain. If you attempt to use previously installed J2EE agent binaries on the same host, but on a different domain, the installation fails. For more information, see Installing a J2EE Agent for a Sun Java System Application Server 8.1 Instance on a Different Server Domain.
To protect content on Sun Java System Application Server 8.1 using an agent, you need to understand DAS. The following is a brief description of administrative domains and how they pertain to DAS.
Administrative domains provide a basic security structure whereby different administrators can administer specific groups (domains) of Sun Java System Application Server 8.1 instances. By grouping the server instances into separate domains, different organizations and administrators can share a single Sun Java System Application Server 8.1 installation.
Each domain has its own configuration, log files, and application deployment areas that are independent of other domains. If the configuration is changed for one domain, the configurations of other domains are not affected. Each domain has its own DAS, with a unique port number.
For more information on DAS and administrative domains, see the Sun Java System Application Server 8.1 Administration Guide.
