Continuous Availability Databases With IBM DB2 Version 9.5 and EMC SRDF
Today's highly competitive business marketplace leaves little room for error in terms of availability, continuous operations, or recovery in the event of an unplanned outage. In today's connected world, an event that makes business data unavailable, even for relatively short periods of time, has the potential to be of major impact. Hence, today's mission-critical database systems must operate 24x7 with the highest degree of availability possible. As databases increase in size, and ad hoc queries place more demands on the continued availability of the system, the time and hardware resources required to back up and recover databases grows substantially while the maintenance windows are either drastically reduced or disappear completely.
