availability - An Oracle Corporation study
to Oracle Corporation studies of client downtime, 34% of downtime can be
attributed to operational outages, or outages that you can control. Another
36% of downtime is caused by design-related issues. Over half of the design-related
issues are due to a lack of adequate documentation. Approximately 5% of
downtime is caused by configuration issues and problems associated with
the setup and installation of the database. All of these outages are issues
that you can control and many times are attributed to poor DBA skills.
This study would indicate that the lion’s share of outages could be prevented. The average corporate out-of-pocket cost for downtime could be reduced by over $4.5 million per year. When adequate preventative measures are applied through the use of appropriate database monitoring procedures, a huge savings can be achieved. Proper expert advice on database configuration, and backup and recovery strategies is equally important in reducing this number to the smallest amount possible.
Finally, the survey showed that the average Mean Time Between Failures (MTBF) was 102 days, and the average Mean Time to Recover (MTTR) was calculated to be 17 hours and 53 minutes. These statistics could be the reality of your users and the company as a whole. Can you afford to have these unexpected outages?
