This configuration shows a service resource group for an instance of DB2 UDB. The db2udb1 resource (the database) requires the IP resource and the Mount resource. The service group IP address for the DB2 UDB server is configured using the IP resource (db2udb_ip1) and the NIC resource (db2udb_nic1). The mount resource (db2udb_mnt1) requires the Volume resource (db2udb_vol1) which in turn requires the DiskGroup resource (db2udb_dg1). The DB2 UDB instance can be started after each of these resources is available.
