Oracle9i readies databases for clustered servers, adds XML

Oracle Corp. has upgraded its flagship database management system for clustering.

Clustered servers reduce the Oracle9i DBMS' downtime'planned and unplanned, said Tim Hoechst, senior vice president of technology for Oracle Service Industries in Reston, Va.
Previous Oracle versions required a separate application, Oracle Parallel Server, to alter the application code for clustered servers.

The company has integrated some features from its earlier Trusted Oracle releases into 9i, Hoechst said. For example, each row of a large table can be labeled for a different level of access.

Administrators can define several levels of user access, and they can perform such online operations as partitioning tables, moving data and rebuilding indexes without taking the database server down, Hoechst said. Statistical analytical tools are part of 9i, and Extensible Markup Language is now a native Oracle data type.

With flashback queries, a user can ask a question based on the database's content at a specific time, Hoechst said.

Subject to interpretation

Also, Oracle has changed its PL/SQL from an interpreted language to a natively compiled language to improve performance, Hoechst said.

The Oracle9i platform consists of the 9i database plus Oracle 9i Application Server middleware. It runs under Compaq Tru64 Unix, Hewlett-Packard HP-UX, IBM AIX, Linux and Sun Solaris operating systems.

Per-processor prices are $40,000 for the enterprise edition, which is designed for high-volume uses such as data warehousing, and $15,000 for the standard edition, for workgroups and application developers, Oracle spokesman Michael Sperling said.
