Instructions below are for the loal setup at SLAC on the hps tracker cpu.

%%% Initial setup

Login to hps tracker computer

$ ssh \-X tracker@ppa-pc88427

Edit the coda setup user script (attached):

CODA

...

Execute the coda setup user script

$ source coda_user_setup

You will now have access to start the mSQL database deamon

$ msqld &

(first time it will complain that it cannot open files and dirs but it creates them afterwards)

Check that the deamon is running (process msqld should be running)

Setup database structure

$ cedit

* File->New Database (enter same name as $EXPID) to make a DB for the experiment * File->New->Config (enter name 'cool') which is the "Run Type" or "configuration" *Create the ROC (one of the icons, try them):     name: ROC1           ethernet host: hpstracker.jlab.org           id: 2           boot string: $CODA_BIN/coda_roc           readout list: /home/tracker/pelle/daq/coda/test_primary/test_primary.so userString The readout list is the configuration that tells coda what this ROC is being readout (see later for details) * Create the event builder (EB)     name: EB1           host: hpstracker.jlab.org (??)           id: 1           booting string: $CODA_BIN/coda_eb          incoming: CODA          outgoing: CODA * Then connect the ROC and EB with an arrow (drag a line between them) * File->Save and then close the dbedit program $ dbedit * choose localhost to find your database in the browser and go to the localhost tab * choose hps_tracker database from drop down list * choose Table cool and you should see the ROC and EB you created earlier * Change EB1 outputs to 'coda'

* go to the 'session' table
* add new row:
    name: pelletest (should be same as your session in the user script)
    id: 10 (should be unique?)
    owner: tracker (should have writeable permissions)
    runNumber: 1 (not sure why)
* quit dbedit program

To clean the database you can remove the content of the cool/ directory.

Setup the ROC and EB executables to use custom binaries built to handle large data frames needed for the SVT (attached)

$ cp coda_roc_rc3.5big 2.6.2/Linux/bin/
$ cp coda_eb_test 2.6.2/Linux/bin/
$ cd 2.6.2/Linux/bin/
$ ln -s coda_roc_rc3.5big coda_roc_rc3
$ ln -s coda_eb_test coda_eb_rc3

%%%%% Each Time Running

ppa-pc88427 ~$ cd pelle/daq/coda
ppa-pc88427 ~/pelle/daq/coda$ source coda_user_setup

Check the msql deamon is running. If not start with:

ppa-pc88427 ~/pelle/daq/coda$ msqld&

First terminal:

ppa-pc88427 ~/pelle/daq/coda$ rcplatform

If it's the first time you should answer 'Y' to the questions.

Example output expected:

CODA setup instructions

CODA 2.6.2 ,Name : ROC1, Type ROC Id : 0
pelletest::ROC1> INFO: Starting up rcClient Thread...Running the cMsg RC client, "ROC1"
  connecting to UDL, cMsg:rc://multicast/hps_tracker
Connect is completed!
subscribing subject = ROC1 type = run/transition/*
subscribing subject = ROC1 type = session/control/*
subscribing subject = ROC1 type = coda/info/*

You should also see that the ROC1 being registered in the rcplatform terminal.

In CODA master:

* Config->Enable buttons
* Click Event Builder

This should open an xterm and you should see EB1 being connected in the logs

* Click Run Control
First time you will need to setup configuration
* Session-> new = pelletest (or what you named you session above)
* options-> coda2 database-> run types = cool
Answer yes to translate
* configurations->cool

This should enable and connect run control properly to the session.

Press  Configure in codamaster

EB1 and ROC1 should be configured

Press download in coda master

EB1 and ROC1 should be downloaded

Press prestart in coda master

EB1 and ROC1 should be paused
