The following new features were introduced in Sun GlassFish Enterprise Server v2.1.1.
Support for Oracle Access Manager (OAM) integration – Enterprise Server v2.1.1 Patch 7 supports integration with OAM security providers. See Using Oracle Access Manager with Enterprise Server for more information.
Support for Per Request Load Balancing — Enterprise Server v2.1.1 supports Per Request Load Balancing (PRLB). PRLB is a new method for load balancing stateless EJBs that enables load-balancing for each request to an EJB instance. Per-request load balancing chooses the first node in the cluster to use on each request. By contrast, the older load balancing model chose the first node to use when the InitialContext was created, and each request thereafter used the same node unless a failure occurred.
PRLB is enabled by means of a new per-request-load-balancing (boolean) property in the sun-ejb-jar.xml file. If this property is not set, the original Load Balancing behavior is preserved.
See PRLB feature in GlassFish 2.1.1 for more information.
Support for the Client-Auth REQUESTED SSL value – Enterprise Server v2.1.1 Patch 6 supports the REQUESTED client authentication option. To enable this support, add the following property to the http-listener element for the domain:
<property name="com.sun.grizzly.ssl.auth" value="want"/>
For more information, see Client-Auth REQUESTED in GlassFish.
