Market leader Oracle fired its latest salvo on Monday when it released Oracle 10g release 2, an upgrade to its "grid" database that adds better security and management.
IBM's response is code-named Viper, the next major edition of its DB2 database, due in the second half of next year.
The company intends to begin an "open beta" program in August or September for Viper, which is now being tested with a small number of customers, according to an IBM representative.
Meanwhile, Microsoft will make its delayed SQL Server 2005 database generally available on Nov. 7.
