* 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
endsw
 
# select 64-bit or 32-bit MIDAS and ROOT
 
switch (`uname -i`)
case i386:
    #export ROOTSYS=/triumfcs/trshare/olchansk/root/root_v5.20.00_SL45_32
    setenv ROOTSYS /triumfcs/trshare/olchansk/root/root_v5.28.00_SL55_32
    setenv PATH .:$MIDASSYS/linux-m32/bin:$PATH
    breaksw

#end
</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>
* 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)
<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
mserver -p 7071 -D
mlogger -D
