 - An instance of Oracle Enterprise Manager 10g Database Control is already running.

从网上找到原因:/etc/hosts文件配置错误造成的,缺少127.0.0.1 127.0.0.1       localhost.localdomain   localhost.

.

修改前hosts文件的内容如下:

[root@zfkdb004 ~]# cat /etc/hosts

10.182.x.x   ZFKDB004        localhost.localdomain   localhost

10.182.x.x   hdi_backup

修改后hosts文件的内容:

[root@zfkdb004 ~]# cat /etc/hosts

10.182.x.x    ZFKDB004             

10.182.x.x    hdi_backup

127.0.0.1     localhost.localdomain   localhost

oracle@ZFKDB004:/home/oracle> emctl stop dbconsole
