Cluster installations
IBM Informix supports Microsoft Cluster Server (MSCS), which enables high
availability on Microsoft Windows (Windows 2003, Windows XP and Windows
Vista). MSCS allows you to cluster two Windows computers as redundant
components, or nodes. When a failure occurs on one node in the cluster, Windows
restarts the failed applications (such as the database server) on the surviving node
in the pair.
Important: The database server installation must include the Cluster utility feature
with appropriate installation configuration to set up an MSCS environment. You
must install the Informix software bundle as documented in “Installing the
Informix server on the primary node of a cluster environment” on page 2-7.
MSCS includes the Cluster Administrator, which enables you to designate a cluster
and define resources, resource ownership, and dependencies on other resources. A
resource is a hardware component, such as a shared disk, or a software
application, such as the database server, that is shared between the two nodes in a
cluster.
The Cluster Administrator also enables you to define groups that specify resource
dependencies, so that the Microsoft Resource Manager can move groups of
dependent resources to the surviving node in the event of failover. The Microsoft
Resource Manager is a program that invokes specific start, restart, stop, and
monitoring functions for a resource.
Important: Stop Informix before shutting down the operating system during MSCS
setup to avoid any data loss.
Overview of implementing a cluster on two nodes
After you complete cluster-implementation preparation tasks, you implement a
clustering environment of the database server in three steps:
1.
On the primary node, install the Informix server as documented in “Installing
the Informix server on the primary node of a cluster environment” on page 2-7.
2. Convert the database servers to a cluster configuration. This step is
implemented with the ClusterIT utilities:
v Use the clusterIT_a.exe utility to configure Informix on the primary node for
use in a cluster.
