Oracle made 11g Release 2 generally available today for Linux. The new version of the database includes a number of enhancements to boost performance, especially involving Oracle RAC.
Oracle pulled the covers off Oracle Database 11g Release 2 today,
bringing a host of new features around performance and management. A year ago, just what would be included in 11g Release 2 was the subject of intense speculation at the Oracle OpenWorld conference in San Francisco. Now, roughly a month before the 2009 conference is set to begin,
Oracle is addressing that speculation with the delivery of several new
features. Chief among them are enhancements to Oracle's Real
Application Clusters (RAC) technology.
In Release 2, Oracle RAC delivers new server pooling capabilities that enable organizations to
reduce their server costs by streamlining the provisioning and
management of consolidated database grids.
"We made it much easier to configure the grid environment," said Marc
Townsend, vice president of database product management at Oracle. "We
have a plug-and-play capability that allows the clusters to be set up
more easily." Release 2 also features Oracle RACOne
Node, a new database option that enables users to consolidate their
less mission-critical database environments on the grid with all of the
redundancy and availability provided by Oracle Real Application
Clusters."This allows a single instance database, a database that runs on one machine in the cluster, to be set up with RAC," Townsend said. The capability
means that if administrators want to perform maintenance on hardware or
the software itself, they can temporarily start another instance of
that database and migrate users back and forth, he said. Oracle also
enhanced its Automatic Storage Management technology to add new cluster
file system capabilities and added a new in-parallel query feature that
boosts performance by allowing users to execute a query against data
stored in memory across all servers in the grid. "If
you have a table that's on disk and you have a number of different
nodes in your cluster, then there's quite a bit of memory accrued
across that cluster...if you have compression around your data, maybe
you're getting a five to one or 10 to one compression ratio,
you can load half a terabyte to a terabyte of data into that memory,"
Townsend said. The initial release supports Linux, with support for other platforms forthcoming. "As
organizations face exponential information growth and complexity
throughout the data center, they are seeking to minimize IT costs and
increase administrative efficiencies," said Carl Olofson, an analyst
in a statement. "Oracle Database 11g Release 2 features enhancements to
grid computing, storage management and administration capabilities that
are designed to help users achieve greater resource utilization of
their information management systems while making the related system
infrastructure and storage easier to manage and more affordable."
