Oracle last week introduced the first new version of its flagship database in four years: Oracle 11g. They also wanted to remind people of its database expertise.
Be that as it may, there were still plenty of questions.
Some of the database’s 500 new features will be offered as separately priced add-ons when 11g becomes available on Linux in August.
However, Oracle couldn’t say specifically which ones. They also couldn’t say when versions of 11g will be available for Unix and Windows.
Oracle president Charles Phillips boasted that 35% of the 20,000 members of the International Oracle Users Group “say they’re ready to go to 11g.”
Charles Phillips declined to speculate on how long it might take before the entire customer base had migrated to the new system.
In 11g, Oracle is pioneering a feature that lets the database take a snapshot of an 11g workload, then run it on a test version of a new database server, which might include a database upgrade, a new operating system or a new middleware-hardware combination.
This real application testing feature or regression testing, as it’s commonly called aims to ensure that everything works as expected. Real application testing is expected to reduce one of the database administrator’s biggest headaches: moving from an old system configuration to a new one.
Another key feature is more efficient XML handling. Verbose XML text, often used in messaging over the Internet, gets translated into binary format and stored in the database. Oracle 11g can compress binary XML to save storage space; it can also encrypt it to ensure privacy.
In another innovation, Oracle has built more usefulness into live standby systems earmarked for disaster recovery.
Instead of keeping the hot standby on idle, Oracle 11g can offload reporting and other noncritical functions to the disaster recovery system, without impairing the database’s ability to be up to date and available at an instant’s notice.
Some of the additions to Oracle 11g are aimed at countering Microsoft, which has been adding business intelligence features into the core of its database system rather than selling them as add-on products.
Oracle has favored the latter strategy, but it has reversed course with 11g by embedding online analytical processing cubes.
Average users, as opposed to highly trained business analysts, can fire standard SQL queries at OLAP cubes and get the benefit of in-depth views of data, such as a time-sensitive look at sales data across multiple regions.
