Oracle Enterprise Manager Cloud Control 12c: how to solve 'ERROR: NMO Not Setuid-root (Unix-only)'

How to solve the error 'ERROR: NMO Not Setuid-root
(Unix-only)' on Oracle Enterprise Manager Cloud
Control while contacting the EM Agent
I've just finished to setup at home an Oracle Real Application Clusters virtual
environment formed by two nodes.
I would like to monitor and eventually execute some commands from another
machine where I've installed the latest (at the moment of this post of course)
available Enterprise Manager Cloud Console 12c that is Oracle Enterprise Manager
Cloud Control 12c Release 3 Plug-in Update 1 (12.1.0.3) which contains the original
12c Release 3 (12.1.0.3) software binaries along with a few new plug-ins and
updated plug-in versions.
I would like to compare the easy way to manage a Real Application Clusters from a
GUI solution against the classic command line interface (CLI).
After I successfully deployed the agents from my Enterprise Manager Clod Control
machine to the two target RAC nodes whenever I tried to perform some operations
they resulted in the following error:
ERROR: NMO not setuid-root (Unix-only)
The following steps helped me to solve the problem.
On my nodes (demorac01 and demorac02) I created a local directory where EMCC
deployed the agent. Let's have a look at the content of that directory in the second
node:

Inside the sbin directory there are other files that according to the Oracle
documentations should be owned by root. During my local deploy they were set up
to be owned by oracle user instead.

Before proceding with the solution adopted just note that the agent was running and
collecting all the available info from the RAC node as you can see from the
command below:

It's time to bounce the agent so the new settings could be used by the Enterprise
Manager Clod Control during its operations. You must stop and start the agent as
oracle user.

I have a RAC with two nodes so the same steps need to be executed on the other
node, demorac01 in my case. Here there are the wrong settings before running the

So both agents are now running again on the RAC nodes. Let's verify that I solved
my issue directly from the Enterprise Manager Cloud Control: the error "NMO not
setuid-root (Unix-only)" was thrown the first time when I tried to start up a pluggable
database.

Let's do the same step again. Here is the current situation: a CDB in open mode
and the pluggable database PDB001 not open.

Click on the target name link named "DEMO.demorac_PDB001". It will open the
following screenshot and information: "Database is not open. Regions that fetch
real-time data from target database will not be displayed"

So I want to open that PDB. Point your mouse over "Oracle Database" menu, then
"Control" and finally "Open/Close Pluggable Database".

Give the credentials to access the remote Oracle database.

It seems to work because the Enterprise Manager Cloud Console is currently
showing a new page.

Because I want to open the pluggable database PDB001 on both the available
instances I select both instances using the CTRL button, and then clicked on
"Open" from the Action menu.

A new browser page will show the status of the operation in progress.

When the operation terminates successfully the "Open/Close Pluggable Database"
page will show that the status of the pluggable database PDB001 is now OPEN.

Clicking on the target link of the pluggable database named
"DEMO.demorac_PDB001" will show new activities are performed and so collected
from the agent.

That's all.
