EMF LTDB configuration at EMF

Jira for issues tracking:

If you have an issue during OpcUaLarLtdbServer (peripheral) operations please:

  1. Create a sub task on ATLLARONL-435 ticket
  2. Assigne Etienne FORTIN


All command are made for a bash shell



  • NEVER RESTART OpcUaLarLtdbServer without having contacted CPPM experts before. This operation can put the system in bad state
  • Restart felixcore / opcuasca server only if there is an issue and the troubleshooter say to do it !

gtbin // attention not the same as P1 gtbin= /ltdb/det/lar/project/LTDB

Set up your bashrc to have command

If your bashrc on pcemf-felix-01 do not contain the specific command to use LTDB's setup (status, ltdbMain ...)

cd /det/lar/project/LTDB/tools

source set_bashrc.sh



This part is only for expert, it may put the system in bad state if used.

Change the FELIX firmware on pcemf-felix-01(if needed)

You need a specific firmware on the pcemf-felix-01's felix : rm-4.10 LTDB, 12-10-2021 at 14h43

To change it :

ssh -X pcemf-felix-01
source /data/FELIX/setup.sh
cd /data/ScriptInitFelix
./disable-minipod.sh    #If forgotten you may have to repower the FE crate
sudo /usr/local/bin/flxpci remove # DON'T FORGET THIS STEP, IF SO YOU MUST REBOOT THE COMPUTER
fflash -f 3 -L -b 1
rm fflash-tmp.txt # this file is created when you do fflash but if someone else did it before, he is the owner of this file and you can't do fflsh. So please clean it (remove) after fflash command
sudo shutdown -r now    ( # there is a bug in flxpci since we are in CC7 don't execute sudo /usr/local/bin/flxpci rescan)

Felix configuration and felixcore start

Kill felixcore if running before you restart it.
ssh -X pcemf-felix-01
gtbin  // attention not the same as P1   cd /ltdb/det/lar/project/LTDB/OpcUaLarLtdbServer
cd Felix/
source configurationFelixScript_productionServer.sh

To check if felixcore is launched:

ssh -X pcemf-felix-01<br />status #you need to edit your bashrc to have this command

To stop this server:

ssh -X pcemf-felix-01
#note the felixcore's PID
kill -9 PID

Ping SCA

To test if all is good you can do a ping of all sca with this scan: The result have to be exactly the sames.

ssh -X pcemf-felix-01
cd /det/lar/project/LTDB/tools/scanSca
source setup.sh
./scan.sh -l 1

Launch OpcUaScaServer

The OpcUaScaServer should automatically be launched by a cron job. However, at the moment we have to start it manually:

ssh -X pcemf-felix-01 
cd OpcUaScaServer/

To restart the server :

ssh -X pcemf-felix-01 
#note the ScaServer's PID
kill -9 PID

To see the logs the server :

ssh -X pcemf-felix-01
#note the last_log_file
tail -f last_log_file

Launch OpcUaLarLtdbServer

The OpcUaLarLtdbServer should automatically be launched by a cron job. However, at the moment we have to start it manually:

ssh -X pcemf-felix-01
cd OpcUaLarLtdbServer/

To see the logs

ssh -X pcemf-felix-01
#note the last_log_file
tail -f last_log_file

The lasts log lines have to be:

 Server opened endpoints for following URLs:
2019-07-30 12:08.17.340425 [BaseQuasarServer.cpp:334, INF] ***************************************************
2019-07-30 12:08.17.340509 [BaseQuasarServer.cpp:335, INF] Press CTRL-C to shutdown server
2019-07-30 12:08.17.340552 [BaseQuasarServer.cpp:336, INF] ***************************************************

To check if the server is launched :

ssh -X pcemf-felix-01

To stop this server:

ssh -X pcemf-felix-01
#note the LarLtdbServer's PID
kill -9 PID


Launch GUI

ssh -X lardcs@pcatllarltdbemf
startPA (only if winccoa server is not launched, after a reboot for ex)
ltdbMain (edit your bashrc)
WCCOAui -proj ATLLARLTDB -p main.pnl

Main panel

The main panel is :


Click on the lonely colored LTDB, we would see the crate's panel, with one LTDB :


This pannel shows the status of all boards and controls the transition for the full system (At EMF only one board for now). A green color on one board means that this board is in good state, a red one that there is an error. The differents states and transitions of LTDB are :


To be ready for data taking the global state must be configured and LTDB green.

For stability issue, you can check the links status by pressing the corresponding button. If the LTDB stay green after that the system is ready ( automatically done after configure).

"Copy state" will copy into clipboard the full status of the system, you can paste it into elog or mail.

Now you click on the part 4, the green zone for E01 for example...appears le LTDB control panel of this E01 LTDB board. Description in the following chapter.

Ltdb monitoring/control panel

In the control panel, as the previous panel, you have the differents transitions: in grey, the transitions that have been yet done.
Every thing is ok if no red messages / no red zone.
The state of the LTDB you are looking should be coherent with the global state: a reminder at the top of the panel.

HOW TO SEE Monitoring: Clicking on the LTDB zone, you can have a look to differents parametres that are monitored: for the moment sca temperatures

Attention: After doing "CONFIG", it's better to click on the "Links Status" to update it.

* LTDB control panel:


* monitoring LTDB panel:

Errors messages:
Follows instructions in the message: go back to the OFF state that means do transitions UNCONFIG and SHUTDOWN in this windows and after returns to the current Global state (here CONFIGURED) doing INIT and CONFIG in this windows (LTDB control panel)


the status of the LTDB is RED= After CONFIGURE, "Links Status " is BAD => Expert can do a scan of the LOCx2 (Expert mode )

3) the log window: Liste of error code and recovery mesure: OpcUaLarLtdbServerTroubleshooter
