You can configure DB2® HADR to
ensure that it integrates with the high availability topology. Cluster
management software can be used to automate the takeover of the primary
server when a failure occurs.
About this task
DB2 HADR can
be configured with a service IP, by using a cluster manager such as IBM® Tivoli® System
Automation for Multiplatforms.
This solution can help to achieve seamless failover in your product
operations. When you configure the database parameters in your product,
specify the service IP as the database server host.
Procedure
Install DB2 on
both systems and create a common DB2 instance
on both.
Configure the product to point to the Service IP as the
database host. If you installed your product before you configured DB2 HADR,
you must redeploy the application with the new Service IP. If you
install the product after you configure DB2 HADR,
you can provide the Service IP and database name during the installation.
