New Features in Message Queue 4.4 Update 1
Message Queue 4.4 Update 1 is a minor release that includes a number of feature enhancements and bug fixes. This section describes the new features included in this release:
New Installation Program
Message Queue 4.4 Update 1 provides a new multiplatform installer based on the pkq(5) system, also known as IPS or Image Packaging System. For information about this installer, see Sun GlassFish Message Queue 4.4 Update 1 Installation Guide.
Transaction Log Support for Clusters
Message Queue 4.4 Update 1 adds a transaction persistence mechanism for file-based data stores that supports broker clusters. This mechanism provides other features as well, as described in Optimizing File-Based Transaction Persistence in Sun GlassFish Message Queue 4.4 Administration Guide.
In-Process Broker
Message Queue 4.4 Update 1 supports running a broker from within a Java client. Such a broker, called an in-process or embedded broker, runs in the same JVM as the Java client that creates and starts it. For more information, see Chapter 6, Embedding a Message Queue Broker in a Java Client, in Sun GlassFish Message Queue 4.4 Developer’s Guide for Java Clients.
