C:\Windows\system32>emctl stop oms -all
EM Configuration issue. D:\app\s_oracle_xyz02srv141\product\11.2.0\dbhome_2/xyz02srv141.abc.com_ORACC not found.
Please check the path of command emctl. The above emctl command is for Grid/Cloud Control. The output indicates that 'emctl' for database control was executed.
Please see the following doc (It is an EM 220.127.116.11 doc, but the commands for starting and stopping an OMS have not changed in recent versions)
