$  cemutlo

Usage: /u01/app/11.2.0.4/grid/bin/cemutlo.bin [-n] [-w]

        where:

        -n prints the cluster name

2.還可以使用olsnodes指令

$  which olsnodes

/u01/app/11.2.0.4/grid/bin/olsnodes

$  olsnodes -h

Usage: olsnodes [ [-n] [-i] [-s] [-t] [<node> | -l [-p]] | [-c] ] [-g] [-v]

        where

                -n print node number with the node name

                -p print private interconnect address for the local node

                -i print virtual IP address with the node name

                <node> print information for the specified node

                -l print information for the local node

                -s print node status - active or inactive

                -t print node type - pinned or unpinned

                -g turn on logging

                -v Run in debug mode; use at direction of Oracle Support only.

                -c print clusterware name

$  olsnodes -c

$  olsnodes -c -v
