In the following examples, VCS is configured on a two-system cluster. DB2 UDB system binaries are installed identically on local file systems on System A and System B. The instance home directory, instance binaries, and the database reside on shared storage, available to either node. In the case of the non-MPP configuration, an instance is online on only one system at a time, while the other system is a failover system.

In the case of the MPP configuration, a database partition can run on each system and each system can become a failover system.
