SYBASE ASE 12.5 HIGH AVAILABILITY

GARBUS

High Availability is a very esoteric area of Sybase administration, yet
a very critical topic for administrators working in a
transaction-intensive environment, such as e-commerce, to understand.
SybaseŠ ASE 12.5 High Availability explains how to use Sybase Adaptive
Server Enterprise software to set up a shared-disk architecture that
enhances the continuous availability of service with no downtime.

Among the topics discussed are the various architecture options for High
Availability; failover and failback; asymmetric and symmetric failover;
and proxy databases. A step-by-step setup process is provided, from
configuring servers for failover and running installation scripts to
establishing connectivity and resolving failed transitions. The authors
outline how to use OpenSwitch to transparently transfer client
connections to any Sybase server product in the event of an Adaptive
Server failure, and describe the special stored procedures used with
OpenSwitch. Additionally, protecting against data loss by using Sybase
Replication Server is covered.

This book is vital for those whose businesses demand 24x7 availability
of data and applications.
