Product Editions

Before the release of Version 3.7 UR1, the Sun Java System Message Queue product was available in two editions, Platform and Enterprise, each containing different features and corresponding to a different licensed capacity. Versions beginning with 3.7 UR1 combine the functionality of both editions. If you have an earlier version installed under a Platform Edition license, upgrading to Version 4.2 will give you access to the full range of Message Queue functionality, including the following features formerly available only under the Enterprise Edition license:

• Multiple-broker clusters

• Scalable connection capability

• Secure connection services

• Hypertext Transfer Protocol (HTTP) and Secure Hypertext Transfer Protocol HTTPS) connections

• Queue delivery to more than three consumers

• C client support

In addition, the following features, added since the Platform and Enterprise Editions were combined, are available to all users of Version 4.2:

• High-availability message services

• Support for plug-in client authentication using Java Authentication and Authorization Services (JAAS)

• Connection event notification

• Client runtime logging

• Enhanced broker administration

• Programmatic configuration and monitoring of Message Queue operations by means of the Java Management Extensions (JMX) API and monitoring by means of the Java Enterprise System Monitoring Framework (JESMF)
