IBM will launch version 5.0 of its DB2 database at DB Expo in San Francisco next week, which is optimised for the Parallel Sysplex version of Big Blue's OS/390-based mainframes.
This means that users can now run one version of the database across a series of clustered boxes, which improves performance and provides them with a single system image. In the past, each machine needed to run its own version of DB2.
But, observers said that users and ISVs would not need to rewrite their applications to take advantage of Parallel Sysplex capabilities. Systems administrators would simply need to reconfigure their software and change the way their applications are defined to the CICS transaction processing monitor.
DB2 version 5.0 also supports C++ and Object Cobol extensions for application development purposes and incorporates DB2 World Wide Web Connection for MVS/ESA. The latter enables users to estimate capacity, model SQL performance, monitor and optimise the DB2 subsystem for Web browsers. It also makes DB2 data available to the Internet.
The offering is scheduled to ship on 27 June.
