Even Oracle Certified DBAs cringe at the thought of performing a real-world database recovery. As disk and hardware has become super-stable, many Oracle DBAs have never experienced the adrenaline rush of a full-blown Oracle recovery.

When user errors and logical corruptions occur in the database, flashback functionalities provide fast and flexible data recovery. When physical or media corruption occurs in the database, RMAN delivers an improved and simplified recovery method.

Being an emergency support DBA is a job with huge stress-levels and it always provides a giant adrenaline rush for even the most experienced DBA. Senior management is in a panic, and high-level executives are continuously asking for a status update. Most of these databases are brand-new to me, and I have only a few minutes to access the situation and devise a plan to quickly relieve their bottleneck.
Oracle Database 10g has expanded the ability to globalize Oracle databases dramatically. As you can see by looking over the following list of globalization improvements, Oracle has attempted to make Database 10g the database of choice for all globally supported and utilized databases.
Oracle databases have many types of auditing features. In mandatory auditing, certain actions are always audited, regardless of the other audit options or parameters. Database activities, such as system startup and shutdown, are always recorded.
