Future releases will include performance and management enhancements, allowing DB2 on the mainframe to more fully exploit IBM's next-generation big iron 64-bit z/0S architecture, according to Tom Rosamilia, vice-president of worldwide data management development.
Rosamilia addressed members of the Chicago-based International DB2 Users Group (IDUG) at its North American 2002 conference.
"The next version of [DB2 on the mainframe] would be the largest DB2 release ever," he said, while promising aids to make migration from previous releases easier. Rosamilia said IBM plans to focus on enhancing DB2's Online Transaction Processing capabilities, as well as its indexing and clustering features.
To help users cope with the "explosion of transactions" DB2 is now supporting, IBM will also boost useability and manageability features across the different lines to "have fewer database administrators per terabyte". On the Web development front, he said IBM would support both Microsoft .net and the industry-standard J2EE specifications.
Looking to reassure Informix users in the audience, Rosamilia said support would continue for both products and customers, even as IBM begins to migrate Informix technology to enhance DB2. IBM acquired Informix last year.
Joseph Burns, a senior database consultant at insurance firm Highmark, said he wants to see IBM allow users to continue to keep DB2 online even after data fragmentation has occurred and the system is reorganising itself.
Currently, to reorganise DB2 has to go offline, he said, "which is not a good thing when people need to access data 24 hours a day". Other vendors already offer this feature, he said.
IBM is working to address the availability issue, said Rosamilia.
