2. Data Stored in Archiver binary format (see below under Data Archiver Storage )

EPICS - Archiver location:

/data2/epics-7.0.2.2/base-7.0.2.2/epics-extensions/archappl


Archiver basics:

How to start  or  stop

cd /data2/epics-7.0.2.2/base-7.0.2.2/epics-extensions/archiver_appliance

./prelim_setupArchiver.sh stop/start

How to launch browser: 

in a terminal execute:

firefox http://localhost:17665/mgmt/ui/index.html &

That should bring up a window like this below  (takes approximately 30 seconds from a remote connection ie LANL to FNAL):


How to check the status of PV or archive a PV?

1.Type (one PV per line) the name of your PV ie T1 and T2 in the example below.

2.Click on Check Status




3.If its not being archived (the case for new PV) click on the Archive button.


4. If its already archived and you would like to inspect its history click on quick chart


4.This should bring you to the history plot. You can choose the time frame of your choice up to one year.


Miscellaneous archiver features:

ARCHIVER Data storage

The short term storage differs from medium/long term locations for the following reasons (Thanks to P. Reimer for pointing this out)


  1. Primarily, if there are network problems, they may effect some links, but at least the Archiver will still be able to store whatever data EPICS has that is valid, regardless of whether or not /data2 is reachable.
  2. If there are network problems, the Archiver will still have access to recent (which we can define) data to serve to which ever clients can reach it regardless of whether or not /data2 is reachable.
  3. The Archiver will respond slightly faster as there is one network hop that it will not have to do when storing or reading data.


Short term: /home/epics/archiver/archappl/sts

Medium Term: /data2/e1039_data/slowcontrol_data/epics_archiver/mts

Long term: /data2/e1039_data/slowcontrol_data/epics_archiver/lts




CS-STUDIO (not EPICS based but this were it was agreed to install)

CS-STUDIO baseline projects

/data2/e1039/daq/slowcontrols/epics/css_projects/CSS/


from the above the following projects have been created:

Hall enviroment:
