Oracle High Availability (RAC, ASM, RMAN, and Data Guard) - A Case Study (5.08MB) Presented at: Rocky Mountain Oracle Users Group (RMOUG) Date: 02/12/2009 Abstract: Businesses today cannot tolerate downtime. Downtime means loss of business, and ultimately loss of revenue to the company. The real challenge of achieving 24/7 availability comes from productively utilizing all the available resources, software, and hardware. This presentation is a case study of one such customer, whose storage array failed during the heavy transaction processing time. We quickly brought the database back up and subsequently got their entire system restored, all the while maintaining at least two copies of production databases. This presentation is a perfect example of how a mission critical production shop can utilize all Oracle HA features such as RAC, ASM, RMAN, and Data Guard to acheive maximum availability.
