我在进行克隆数据库操作时，在源选项点下一步出现如下错误：
解决方法:
重新执行$ORACLE_HOME/root.sh,问题得到解决.
因数据库安装过程中已执行root.sh,怀疑是重建EM后需要重新执行root.sh,经测试不是,没有找出引起问题的原因.
ERROR: NMO not setuid-root (Unix-only)错误的解决方法
1、Was the root.sh script. ran?
1)、停止EM
[oracle@rtest ~]$ emctl stop dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0

https://rtest.localdomain:1158/em/console/aboutApplication
Stopping Oracle Enterprise Manager 11g Database Control ...
... Stopped.
2)、运行root.sh
[root@rtest ~]# /u01/app/oracle/product/11.2.0/dbhome_1/root.sh
Performing root user operation for Oracle 11g
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/11.2.0/dbhome_1
Enter the full pathname of the local bin directory: [/usr/local/bin]:
The contents of "dbhome" have not changed. No need to overwrite.
The contents of "oraenv" have not changed. No need to overwrite.

3)、启动EM
[oracle@rtest ~]$
[oracle@rtest ~]$ emctl start dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.3.0

[oracle@rtest ~]$
2、Check the permission of the nmo and nmb executable found in $ORACLE_HOME/bin or $AGENT_OH/bin. Both should have the following permissions
[oracle@rtest ~]$ cd $ORACLE_HOME/bin
[oracle@rtest bin]$ ls -al nmo
-rws--x--- 1 root oinstall 44691 Jun 20 08:27 nmo
[oracle@rtest bin]$ ls -al nmb
-rws--x--- 1 root oinstall 34420 Jun 20 08:30 nmb
