Hi Will,

 

Yes, a more advanced tool is needed to manage IOCs which are wrapped by procServ as background daemons. At NSLS-2, we have developed such a tool named “manage-iocs” which works on all Linux distributions (Debian, Red Hat, etc.) and we have been using this tool for over 10 years. Check it out: https://github.com/NSLS-II/systemd-softioc

 

Please take a few minutes to read the instruction. We also have Debian and Red Hat packages for that tool if you are interested in. Let me know if you need further assistance.

 

Cheers,

Yong

 

 

Hi!

 

I have been using procServ for a while to run my IOC’s in the background. There are now too many and I want to learn how to use manage-procs, part of procServUtils to create and start processes and configure the conserver.cf file to view those processes from conserver. Here’s what I’ve done:

 

-Installed procServ, and included the procServUtils in the build

-Installed conserver

-Set up an IOC that I have tested can start from the command line, or with procServer

 

If I go to the directory containing the st.cmd file and type:

 

manage-procs add -P 7010 -A -f sampleIOC1 ./st.cmd

 

I expect the IOC to start and be accessible on telnet port 7010. Instead I get the following message which I don’t understand:

Created symlink /home/emil/.config/systemd/user/multi-user.target.wants/procserv-sampleIOC1.service → /home/emil/.config/procServ.d/procserv-sampleIOC1.service.

Created symlink /home/emil/.config/systemd/user/procserv-sampleIOC1.service → /home/emil/.config/procServ.d/procserv-sampleIOC1.service.

Failed to start procserv-sampleIOC1.service: Unit procserv-sampleIOC1.service has a bad unit file setting.

See user logs and 'systemctl --user status procserv-sampleIOC1.service' for details.

 

If I look in that file, I get the following:

 

cat /home/emil/.config/procServ.d/procserv-sampleIOC1.service

 

[Unit]

Description=procServ for sampleIOC1

After=network.target remote-fs.target

ConditionPathIsDirectory=/home/emil/Apps/epics/R7.0.4.1/work/ioc/TEST/sampleIOC/iocBoot/iocsampleIOC

 

[Service]

ExecStart=None --user sampleIOC1

RuntimeDirectory=procserv-sampleIOC1

StandardOutput=syslog

StandardError=inherit

SyslogIdentifier=procserv-sampleIOC1

 

[Install]

WantedBy=multi-user.target

 

If I look at the systemd process that failed to start I get:

 

Jun 11 16:40:46 sissy-serv-02 systemd[29562]: /home/emil/.config/procServ.d/procserv-sampleIOC1.service:9: Executable "None" not found in path "/usr/local/sbin:/usr/local/bin:/usr/sbin:/us…..

 

Any idea what I am doing wrong?

 

Thanks,

 

Will
