---+ DQM Online training

---+++ 1. Execution Environment

Request a virtual machine to the CERN Virtual Machine Service (http://vmm.cern.ch), the following are expected features:

- Operating System: SLC5-x86_64

- RAM Memory: 2GB

- CPU: 1 core

- Hard Disk: 40G

---+++ 2. DQM GUI Installation

=mkdir testGui=

=cd testGui=

=DQM_HOME=$PWD=

=svn co svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure/trunk/Deployment cfg=

#
=svn co -r 15374  svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure/trunk/Deployment cfg=
#

=$DQM_HOME/cfg/Deploy -t MYDEV -s "prep sw post" $DQM_HOME dqmgui/bare=

---+++ 3. Starting the DQM GUI server

=$DQM_HOME/current/apps/dqmgui/etc/profile.d/env.sh=

=$DQM_HOME/current/config/dqmgui/manage restart "I did read documentation"=

Other options of the previous command include start, stop and status.

---+++ 4. Setting the DQM GUI Index

=cd $DQM_HOME/state/dqmgui/dev=

=visDQMIndex create ix=

- In order to load a valid histogram, download one or more from https://cmsweb.cern.ch/dqm/offline/data/browse/ROOT/ and then copy them to the virtual machine

=scp [root file name].root [virtual machine hostname]:/$DQM_HOME/state/dqmgui/dev/uploads/=

=visDQMIndex add . $DQM_HOME/state/dqmgui/dev/ix . $DQM_HOME/state/dqmgui/dev/uploads/*.root=

---+++ 5. STG Installation

STG is the patch manager used for the DQM GUI tool patches.

<verbatim>

sudo mkdir guiworkspace

cd guiworkspace/

STG_HOME=$PWD

sudo mkdir Infrastructure

sudo yum install git.x86_64 1.7.4.1-1.el5

sudo yum install git-all.x86_64 1.7.4.1-1.el5

sudo yum install gitk.x86_64 1.7.4.1-1.el5

sudo yum install gitweb.x86_64 1.7.4.1-1.el5

sudo yum install stgit.noarch

mkdir ~/.stgit

ln -s stg/stgit/templates ~/.stgit

git config --global user.name "[your name]"

git config --global user.email "[your CERN email]"

git config --global svn.addAuthorFrom true

git config --global svn.useLogAuthor true

git config --global color.diff auto

git config --global color.status auto

git config --global color.branch auto

(echo "Host *" echo " ControlMaster auto" ) >> ~/.ssh/config

ssh -Nf svn.cern.ch

nano ~/.ssh/config

</verbatim>

If it is present, delete the line: =echo " ControlPath $HOME/.ssh/%h.%p.%r"= and save the changes.

<verbatim>

git svn clone svn+ssh://svn.cern.ch/reps/CMSDMWM/Infrastructure -s

cd Infrastructure/

git config branch.master.remote svn

git config stgit.pull-policy fetch-rebase

git config stgit.fetchcmd "git svn -i trunk fetch"

git config stgit.rebasecmd "git svn rebase"

touch .git/FETCH_HEAD

stg init

stg branch -c mydev

git config branch.mydev.remote svn

</verbatim>

In your home directory:

<verbatim>

sudo git clone git://repo.or.cz/stgit.git

cd stgit

sudo yum install asciidoc

sudo make prefix=/usr all doc

sudo make prefix=/usr install install-doc

</verbatim>

---+++ 6. Patch Management (Testing and deploying render plugins and layouts).

Remember to set $DQM_HOME variable as your DQMGUI installation directory (see step 2).

New patches will be available in the directory: 

=/afs/cern.ch/user/c/cmsdqm/scratch/gui-patch-dropbox/=

They must be moved to the test directory:

=mv /afs/cern.ch/user/c/cmsdqm/scratch/gui-patch-dropbox/* /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]=

Remember to set STG_HOME variable as your STG workspace (see step 5):

=cd  $STG_HOME/Infrastructure/Deployment/dqmgui/=

Create a patch that will compile all of the pending patches that are not STG based (if there is one already in place for the current week just skip next line):

=stg new -m "RP Layouts WS update" rp-layouts-ws-h$(date +%m%y)=

For DQM general patches:

=cat /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[new patch name] | patch -p[0-4] --dry-run=

=cat /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[new patch name] | patch -p[0-4]=

For DQM STG based patches:

=stg import /afs/cern.ch/user/c/cmsdqm/scratch/patches-under-test/[current month directory]/[ new patch name]=

Then for both cases:

=stg refresh=

=stg series=

This command should show the current patches. 

Then you should mix the new patch with the one that you have created in order to compile the patches:

=stg squash -n rp-layouts-ws-h$(date +%m%y) rp-layouts-ws-h$(date +%m%y) [patch name]=

=stg refresh=

=stg series=

=stg show=

This command should show the mixed body of the patches.

=cd $DQM_HOME/cfg/dqmgui=

=svn revert -R .;svn status | awk '/?/{print $2}' | xargs rm -rv; svn up ;=

This command will reverts the directory to its original state  and apply the lastest updates.

<verbatim>

cd  Infrastructure/Deployment/dqmgui/

stg export -d $DQM_HOME/cfg/dqmgui -p -n

. $DQM_HOME/current/apps/dqmgui/etc/profile.d/env.sh

cd $DQM_HOME/cfg/dqmgui

cat [patch name] | patch -p[0-4] --dry-run

cat [patch name] | patch -p[0-4]

$DQM_HOME/cfg/Deploy -t MYDEV -s sw $DQM_HOME dqmgui/bare

monControl rebuild all from $DQM_HOME/current/config/dqmgui/[config file changed]

$DQM_HOME/current/config/dqmgui/manage restart  "I did read documentation".
