* Setup the user account for running this instance of midas. For machines part of the LADD cluster, follow these <a href="http://daq-plone.triumf.ca/SM/docs/local/NewLaddUser">instructions</a></li>
* check that the account is using the /bin/tcsh shell
* make $HOME/.cshrc look like this:
<pre>
#!/bin/echo You must source
 
setenv LANG C
setenv SVN_EDITOR "emacs -nw"
setenv CVS_RSH ssh
setenv MIDASSYS $HOME/packages/midas
setenv ROOTSYS  $HOME/packages/root
setenv MIDAS_EXPTAB $HOME/online/exptab
 
# setup the MIDAS mserver
 
switch (`hostname`)
case ladd05*:
    unsetenv MIDAS_SERVER_HOST
    breaksw
default:
    setenv MIDAS_SERVER_HOST ladd05.triumf.ca:7071

</pre>
* mkdir $HOME/packages
* Logout and login again, for .cshrc changes to take effect
 
=== Install ROOT ===
 
* Identify the Linux version: RH9 (Red Hat Linux 9), FC3 (Fedora Core 3), RHEL4/SL4 (Red Hat Enterprise LInux 4/Scientific Linux 4), SL5, SL6: more /etc/redhat-release
* Decide to use 32-bit or 64-bit ROOT
* cd $HOME/packages
* ls -l /triumfcs/trshare/olchansk/root/ ### to see all available ROOT packages
* ln -s /triumfcs/trshare/olchansk/root/root_vNNN_VVV_BB root, where NNN is the latest available version of ROOT ("ls -l /triumfcs/trshare/olchansk/root"), VVV is the Linux version code (RH9, FC3, SL4, etc) and BB is "_32" or "_64" for 32-bit or 64-bit ROOT. For example: /triumfcs/trshare/olchansk/root/root_v5.10.00_SL40
* Check that ROOT works: "echo $ROOTSYS", "$ROOTSYS/bin/root"
 
=== Install MIDAS ===
 
* cd $HOME/packages
* svn co svn+ssh://svn@savannah.psi.ch/repos/meg/midas/trunk midas, password "svn". (password has to be entered twice)
* svn co svn+ssh://svn@savannah.psi.ch/repos/meg/mxml/trunk mxml
* cd midas
* make
* (only if needed) make linux32 ### build the 32-bit MIDAS libraries
* ls -l linux/bin/odbedit ### check that odbedit has been created (do not run it yet)
 
=== Install ROOTANA ===
 
* cd $HOME/packages
* svn checkout https://ladd00.triumf.ca/svn/rootana/trunk rootana (say "p" to accept the ladd00 ssl certificate, use username "svn", password "svn")
* cd rootana
* make
 
=== Install ROODY ===
 
* cd $HOME/packages
* svn checkout https://ladd00.triumf.ca/svn/roody/trunk roody
* cd roody
* make
* $HOME/packages/roody/bin/roody, run the program
 
=== Prepare VME hardware ===
 
Hardware check list:
* VME crate
* VME processor (supported are V77xx, V7805, V7865)
* On all VME modules, set the VME address jumpers as described here: http://daq-plone.triumf.ca/SM/docs/local/vme_jumpers
* run vmescan to confirm correct VME addresses
** cd $HOME/packages
** svn checkout https://ladd00.triumf.ca/svn/daqsvn/trunk/vme
** cd vme
** make
** ./vmescan.exe (or _gef.exe, depending on the VME driver in use)
 
=== Setup the experiment environement ===
 
* decide which computer will host MIDAS (where MIDAS shared memory buffers will reside). This computer will run the mserver, mlogger and mhttpd.
* in .cshrc put the name of this computer into the section for setting MIDAS_SERVER_HOST. Note that multiple experiments can run on the same computer by using different mserver ports (7071, mhttpd ports (8081) and roody ports (9091)
* mkdir $HOME/online
* cd $HOME/online
* mkdir bin src elog history
* mkdir -p /ladd/data1/t2kvme5/data; ln -s /ladd/data1/t2kvme5/data $HOME/online
* create the exptab file "$HOME/online/exptab" following the example below. The first entry (exptname) is the name if the DAQ system (MIDAS experiment name), the second entry (/home/USER/online) is the location of MIDAS shared memory buffers (by convention, $HOME/online), the third entry (kopio03) is your username.
<pre>exptname /home/kopio03/online kopio03</pre>
* logout and login again for all changes to take effect
 
=== Setup experiment startup scripts ===
 
* login to the experiment host computer
* echo $MIDAS_SERVER_HOST ### to check correct value - should be blank
* create $HOME/online/bin/start_daq.sh, replacing XXX with the hostname of the machine running the experiment (and changing the mserver and mhttpd ports, as needed), replacing machine names in the access control list for mhttpd and mserver as needed. (NOTE: mhttpd ladd00 permission is for password-protecting the experiment via the password protected SSL proxy at https://ladd00.triumf.ca/expt/dragon/, see ladd00:/etc/httpd/conf.d/ssl.conf)
<pre>
#!/bin/sh
 
cd $HOME/online
 
case `hostname` in
XXX*)
    echo "Good, we are on XXX!"
    ;;
*)
    echo "The start_daq script should be executed on XXX"
    exit 1
    ;;
esac
 
odbedit -c clean
 
mhttpd  -p 8081 -D -a ladd00.triumf.ca -a localhost -a XXX.triumf.ca
mserver -p 7071 -D -a localhost -a lxdragon01.triumf.ca -a lxdragon02.triumf.ca -a XXX.triumf.ca
mlogger -D
 
#end file
</pre>
 
=== Setup experiment database (ODB) ===
 
* run $HOME/online/bin/start_daq.sh
* open the midas status page at http://localhost:8081 (you will see most stuff "red" as nothing is running yet)
* create a frontend program (mlogger will not run without at least one equipment)
** cd $HOME/online/src, copy Makefile, fevme.cxx
** make (creates fevme.exe or fevme_gef.exe executable)
* run ./fevme.exe (on the computer with the VME interface, could be different from computer hosting the experiment), observe that corresponding equipments have been created
* odbedit, run these commands: (replace user names and directory names)
<pre>
set "/Logger/Message file" "/home/kopio03/online/midas.log"
set "/Logger/Data Dir"    "/home/kopio03/online/data"
create STRING "/Logger/History dir"
set "/Logger/History dir"  "/home/kopio03/online/history"
create STRING "/Logger/Elog dir"
set "/Logger/Elog dir"    "/home/kopio03/online/elog"
exit
</pre>
* run $HOME/online/bin/start_daq.sh (observe that mlogger has started)
* odbedit, run these commands: (replace user names and directory names)
<pre>
set "/Logger/ODB dump file" "/home/kopio03/online/history/run%05d.xml"
set "/Logger/ODB dump" "y"
set "/Logger/Channels/0/Settings/Filename" "run%05dsub%03d.mid.gz"
set "/Logger/Channels/0/Settings/Subrun byte limit" "1000000000"
set "/Logger/Channels/0/Settings/Compression"  1
set "/Logger/Channels/0/Settings/ODB Dump" "y"
set "/Programs/Logger/Required" y
set "/Programs/Logger/Start command" "mlogger -D"
set "/Programs/fevme/Required" "y"
set "/Programs/fevme/Start command" "ssh -n lxdaq09 $HOME/online/src/fevme_gef.exe -O"
exit
</pre>
* open web browser: firefox http://localhost:8081
* save the url bookmark to the "personal toolbar"
* go to the Programs page, stop mlogger, stop fevme, start mlogger, start fevme
* go to the Status page, start run, stop run
* go back to the Status page, everything should be green
* start a run
* send signals to the ADC gate
* you should be getting events
* to look at data, proceed with setting up the <a href="../../../SR/rootana">ROOT analyzer</a>
