Power Outage Disaster Management of Oracle Database Server
It is not easy to manage power outage disaster but you can deploy some prior techniques to eliminate this issue for your 24/7 running Oracle database server.
High availability solutions to withstand natural or man-made disasters can get very expensive. Geographically replicated data centers including hardware and software via geo-mirrors may ensure database availability during disasters. As mentioned earlier, it is important to evaluate whether availability is still desired during natural or man-made disasters. During a war, for example, availability may not be required. However, the answer to this question eventually depends on the scope of operations of the company and its market. For example, if the market for a product or service sold by the company exists beyond the affected geographical area or the company has branch offices in countries not involved in the war or the company supplies key defense equipment, the company many have to remain operational even during a war. This analysis should be done fairly early and integrated into the service level agreement.
We cannot able to restrict power outage kind of disaster but we can able to deploy vxfng some survival techniques. Using this kind of techniques, we can survive our database server up to certain time, for example, if we have UPS limit 4 hours then we can bring up our database servers for 4 hours during power failure. During this UPS switching, we can switch down all monitors for saving more UPS power or bring down non important database server which are not running 24/7 environment. This is best technique to use UPS appropriately.
