Oracle 11g: Does The 'G' Stand For Green Or Greenbacks?

Oracle's 11g has a large number of new features primarily affecting DBAs and developers. Test Center reviewers took a look at a few of the more publicized and anticipated ones.
One such feature is Active Data Guard (ADG), an enhancement to Data Guard. Active Data Guard enables read-only access to a physical standby database for realtime tasks such as querying and reporting--helpful because it lessens the workload of the production database. ADG can perform fast, incremental backups on a physical standby database, again lightening the load on a production database. This is an option available in the Enterprise edition only.
An additional component has to be installed with the Enterprise edition: the Enterprise Manager Grid Control, which is not included with the default Enterprise install.
Audit Vault is a security repository in which DBAs can collect and consolidate audit data. Audit Vault is also available as an add-on.
Encryption in 11g is done at the tablespace level. An encryption key in this version is stored in a hardware security module--a black box.
There are a slew of other new features in Oracle's 11g, including four new data types:
• Binary XML, which is up to 15 times faster than XML LOBs
• DICOM, a data type used for digitized medical images
• 3-D Spatial
• RFID tag
There are also new memory areas for caching query results, and "Hot Patching" is another feature that allows for applying updates and patches without taking databases offline.

HED: Security Measure
With 11g, Oracle has addressed both the demands for greater database security and the need to met regulatory compliances HIPAA and Sarbanes-Oxley with the development of security enhancements of two features: Database Vault and Audit Vault.
Database Vault is designed to combat internal users with malicious intent--the most common cause of security breaches.
Database Vault provides hearty auditing, out-of-the-box security reports and even tracks and controls application and data access of super-users. Database Audit is available in Release 2 version as an add-on for both 10g and 11g version.
