用emctl启动Oracle控制台报错ERROR: NMO not setuid-root (Unix-only)

一台服务器上运行多个数据库,EM无法正常使用,通过emca重建EM.命令如下:

emca -config all db -repos recreate

启动EM

emctl start dbconsole

说明:

上面的命令会启动agent和dbconsole,同先运行emctl start agent再运行emctl start dbconsole的结果相同. emctl stop agent和emctl stop dbconsole都会停止agent和dbcosole.

用EM进行backup,提示如下错误:

Validation Error

Examine and correct the following errors, then retry the operation:

Error- Connection to host as user oracle failed: ERROR: NMO not setuid-root (Unix-only)

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

       2)、运行root.sh

       3)、启动EM

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

ls -al nmo

ls -al nmb

-rwsr-s--- 1 root oinstall 19656 Jan 9 14:28 nmo

-rwsr-s--- 1 root oinstall 18462 Jan 9 14:28 nmb

If not, change the permissions to match the above.
