02 Jul 2009 EMC Symmetrix Remote Data Facility (SRDF) software, suspend I/O features available in operating systems,
and IBM® DB2® Version 9.5 for Linux®, UNIX®, and Windows® (DB2 9.5) software combine to provide highly available advanced database
technical architectures to meet the most stringent demands for data availability. In this article, learn how to use
these features to create a coherent copy of a continuously available DB2 9.5 database to meet the increasing availability
requirements demanded in today's business environment.

- Usage scenarios
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 have a major impact.
Hence, today's mission-critical database systems must operate 24 x 7 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.
EMC Symmetrix Remote Data Facility (SRDF) software, suspend I/O features in operating systems, and DB2 9.5 for Linux, UNIX, and
Windows software combine to provide highly available advanced database technical architectures to meet those demands. In this
paper, we demonstrate the use of these features to create a coherent copy of a continuously available DB2 9.5 database to meet
the increasing availability requirements demanded in today's business environment.
