安装Oracle 10gR2的时候报错了：
[root@rac1 ~]# cd /opt/clusterware/rootpre/[root@rac1 rootpre]# ./rootpre.sh No OraCM running
405986.1
The rootpre.sh shell script is used to determine if 9i Cluster Manager exists on the node/s & is running.It will locate the 9i srv configuration device file from /var/opt/oracle/srvConfig.locIf 9i does exist it will modify the above file with an entry of &oracle账号#39;/dev/null'The point to doing this is to allow 10g OCR to manage the existing 9i environment.Now if no 9i environment exists on the node/s & this is a clean/new environment the script will exit with the message =>" No OraCM running "This is a normal exit code since it did not find any 9i clusterware present.
也就是说，不用管。。
