Beside Oracle as a relational database system the database IBM DB2 belongs to the most common database management systems. In differnt operating systems it is installed as database in larger environments, e.g. SAP. But also in smaller environments it is possible, e.g. configurations without access to an external storage subsystem. In all sceneries their availability for failure-free operation is very important for the users.

With LifeKeeper for Linux there is a solution that increases availability of DB2.

Some configurations are shown in the following pictures.

On each of the both servers is one active database instance running. Each server is failover target for the other.

Per server one DB2 instance is protected by a Database Partition Server in the LifeKeeper. Thereby one DB2 resource hierarchy was created per node. In case of failure of a server the respectively other server acts as failover target.

In this configuration on 4 servers are several Database Partition Servers protected. For each server there is one DB2 ressource hierarchy in the cluster. Each server can be failover target for a failed node. In such configurations n-way failover and cascading failover can be realized.
