IBM® Informix® 12.10
Microsoft failover clustering support (Windows)
IBM® Informix® database server supports Microsoft Failover Cluster (known as Microsoft Cluster Server, or MSCS, in earlier Windows releases). That built-in feature of the Windows operating system can automatically detect and respond to server or application failure, and can balance server workloads.
Important: During setup of the Microsoft failover cluster environment,
stop the database server before you shut down the operating system
to avoid data loss.
Refer to the Microsoft documentation for details about installation and configuration.
For a list of the Windows versions that Informix supports, go to Informix Server System Requirements (http://www.ibm.com/support/docview.wss?uid=swg27013343).
