Taking the Black Magic Out Of Oracle Database Recovery

Introduction:

One of the biggest issues seen today with an Oracle database recovery is human error. More damage is done by administrators executing commands without a true understanding or an appreciation of the real condition of the existing Oracle database. Since the release of 11g it is interesting to question, how many administrators are actually using the RMAN recovery advisor which is now a tool built into the database?

The aim of this attached paper is to show that database recovery is not black magic. If a deep breath is taken at the point of failure and time is taken to properly diagnose the real condition of the database, whilst forming a firm action plan from what is available, and then the recovery becomes a simple straight forward process. That is providing any required backups are actually available of course!

Experience has shown that the main issue at the time of any fault is an administrator that jumps straight to the recovery phase with little or no analysis of the actual situation, potentially causing a bad situation to suddenly become worse.
