DB2 UDB service groups for MPP configuration

The DB2 UDB agent uses two service groups to support MPP configuration for DB2 version 8.1 and above.

The first service group is a parallel CVM service group. There is one CVM/Infrastructure group per cluster node. This service group has the CVM resource and the necessary resources for support of CFS. This group also contains all common components needed by DB2, such as the instance's home directory, which is shared on all the cluster nodes.

The second service group is a failover DB2 service group. This service group monitors one database partition for DB2 version 8 with MPP configuration. The failover DB2 service group depends on the parallel CVM service group with online local firm dependency.
