Active Data Guard – what does it mean?

There are misconceptions and half-truths about that term that I see time after time again in forums, postings and comments.

Some people think that Active Data Guard is a fancy marketing term for Standby Databases in Oracle. Wrong, that is just plain Data Guard :-)

Most people think that Active Data Guard means that a Physical Standby Database can be used for queries while it is still applying redo. Not the whole truth, because that is just one featureReal-Time Query – which is included in the Active Data Guard option.

Active Data Guard is an option, coming with an extra charge. Active is supposed to indicate that you can use the standby database for production usage – it is not just waiting for the primary database to fail.

In 11g, Active Data Guard includes three features:

Speed up Import with TRANSFORM=DISABLE_ARCHIVE_LOGGING in #Oracle 12c

A very useful 12c New Feature is the option to suppress the generation of redo during Data Pump import. I was talking about it during my recent 12c New Features class in Finland and like to share that info with the Oracle Community here. My usual demo user ADAM owned a table named BIG with one index on it. Both were in LOGGING mode when I exported them. The Data Pump export did not use any 12c New Feature and is not shown therefore.
