Dear all!
First, I am new to tango controls. However, I managed to install tango (with mysql) using the packages provided in the ubuntu 17.10 repositories. I could start a server/device which I downloaded from the big collection of servers. I see, that my computer runs the tango-db service, the tango-accesscontrol service and the tango-Starter service. I can bring up the java applications like astor and jive (for this see my comment below).
Now, I would like to know, how to handle access for users and devices, commands etc.? I have seen in the docs that there is Tango Access Control, but I can not find the window to configure something.
I really appreciate your help, some TAC for Dummies.
Thanks a lot and best wishes
Markus
Comment on java apps when running ubuntu 17.10:
the tango java apps are not part of the ubuntu repositories
What I did was:
downloaded the tango source tarball tango-9.2.5a.tgz
extracted it and executed the ./configure script
the script has to run completely to setup the Makefiles in the subfolder, therefore it might be necessary to install development packages for zmq, omniorb ..
The latter will first build a deb-package and install this, so the just installed tango java apps will appear in the database of the apt packet manager.
No, that is my (current) problem.I can start Astor, but I do not find the TAC window. I am quite sure, that i didn’t overlooked it in the menu.
However, tac is listed by jive.
I am wondering whether this might be related to the fact that the servers are not controlled? They are started upon booting by the linux startup scripts. If important, how to make them controlled?
You can get the TAC window in Astor from the “Tools” menu and then “Access Control”, or with CTRL-A shortcut.
You can also right-click on “Access Control” and select “Manager Panel”.
[quote=“Andy”]default passwd by default is “SUPER_TANGO”. Once you have the Tango Access Control Manager window opened from Astor,
click on “File/Change Password” menu to change it.

I think astor and TAC documentation should be improved because basic information like this one does not seem to be listed there.

Your problem was not linked to the fact they were listed as not controlled.
You can use the Starter instead of using your Linux startup script to start up the device servers upon Linux boot.
In this case, you only have (it might be done by default, depending on how you installed the Starter) to configure your system to start up automatically the Starter at Linux boot and the Starter will take care of starting the controlled device servers.
To make your device servers controlled by the Starter, you need to ensure the Starter is started on the host you want to start your device servers.
Then in astor, open the control panel related to this host (double-click on the host or right-click => Open control Panel).
In the control panel, you can start new instances of device servers using “Start New” button. Once the device server is started, astor will ask you whether you want to be able to control it via astor. Click Yes and select a startup level and your device server will be controlled by astor/Starter from this moment on.
If not controlled device servers have already been running on your host, you can also double-click on “Not Controlled” in your host control panel. The device servers which are not controlled will then appear.
You can then right-click on the instances you would like astor/starter to control and select “Set startup level”.
You can then click on “Yes” (Controlled by Astor) and select a Startup level.
Below steps will help you to see the Tango Access Control (TAC) window in Astor. (These steps are already documented in the link shared by Philippe in the previous post.)
Step-1
Create a free property in Jive with the name CtrlSystem and then add a new property field with the name Services and initialize its value as AccessControl/tango:sys/access_control/1 (see attached screenshot).
Step-2
Start the TangoAccessControl device server from the terminal using below command:
Step-4
In the Astor window, go to Tools > Access Control. In the prompt, provide SUPER_TANGO as the password and the TAC window will be displayed (see attached screenshot).
You may also refer the previous post by Reynald on making the TAC device server controlled by Starter device. By doing this, TAC device server will be automatically started when the Starter device server is started on your system.
Following links has relevant documentation related to Astor and Starter:
thank a lot for all the answers so far. I followed the steps given by Jyotin. I can now open the Manager Panel for AccessControl with the given PW but it opens in read only mode (see attachment). It appears that I can change the PW but actually it does not: an error message comes up after confimation of the new PW (see 2nd attachment).
I am still using tango from the ubuntu repositories with a fresh mysql installation.
Hi Markus
I do not understand exactly what you want to do
It seems your are just installing TANGO.
The TAC is an advanced feature. Do you really need it ?
I can see on your Astor dump, there is no host to control. Why do you need a TAC ?
I think you’d better configure your control system before and add the TAC after if it is necessary.

yes, this might be a way. At the moment I am just playing around to find out, how much effort is needed to get things running.
But I am wondering, how large facilities set up things without TAC and at the same do not run into problems, e.g. due to some inexperienced user hitting/clicking the wrong button that vents the storage ring
(okay, I am exaggerating a little bit, ).
To make my intention more precise (and abusing the thread …).
We are going to install a camera on an electron microscope which comes with a Tango Control interface.
We want to run certain measurements where it is necessary to control the microscope and the camera in concert.
However, we are wondering whether Tango might be also useful for controlling other microscopes as we developing protocols that combine the data from several machines but from the very same sample spot.
In addition, as far as I understood, there are also Tango devices which can help with (meta) data storage(?). This is an important issue, too.
there is expertise in devices control at my place (Helmholtz Center Berlin), but the colleagues at BESSY are using EPICS.
Perhaps you, or the others can suggest a straighter way to get things running.
However, I managed to install tango (with mysql) using the packages provided in the ubuntu 17.10 repositories. I could start a server/device which I downloaded from the big collection of servers. I see, that my computer runs the tango-db service, the tango-accesscontrol service and the tango-Starter service. I can bring up the java applications like astor and jive (for this see my comment below).
