Sun Microsystems aims to make its mark in the Java application server space with its upcoming Sun ONE Application Server 7 Enterprise Edition. 

Having trailed companies such as BEA Systems and IBM in market share, Sun is looking to turn things around by focusing on a high-availability database layer in a product based on the technology garnered from its 2002 acquisition of Clustra Systems.

Sun intends its high-availability technology to ensure 99.999 uptime for key applications such as e-commerce transactional systems. 

The high-availability database layer features transaction state information, and transactional loads can be shifted between application servers in the network as needed. 

Version 6.5 of the enterprise application server has had high-availability support, but Version 7's support of the Clustra technology boosts real-time database functionality and scalability to 24 processors per system. Version 7 is also compliant with the J2EE 1.3 Java specification.

Sun will add J2EE 1.4 compliance to the application server, featuring conformity to web services specifications, next year. 

Load balancing in Version 7 will enable uptime when taking down an application server for maintenance. The high-availability layer also enables performance boosts through the addition of more processors, rather than having to add more application servers.
