Ask Andy Haas to install new releases for you!

-------------------------------------------------------
0) HN/e-news announcement of new release pacman package
https://groups.cern.ch/group/hn-atlas-releaseKitAnnounce/default.aspx ------------------------------------------------------------------

1) Before starting a new install, set up the environment variables:

RHEL4-32 bit: built on atlas-prod02.slac.stanford.edu
pacman version = 3.26
AFS: /afs/slac/g/atlas/d/ (currently soft linked to /b/)

...

:

...

RHEL5-32 bit: built on atlas-prod05.slac.stanford.edu pacman version = 3.29
AFS: /afs/slac/g/atlas/c/ For some reason, it's necessary to unset PYTHONPATH

Code Block
export PATH=/bin:/usr/bin:/usr/etc:/usr/afsws/bin:/usr/afsws/etc:/usr/bin/X11:. unset PYTHONPATH . /afs/slac/g/atlas/packages/pacman/3.29/setup.sh

...

2) Go to the target release partitions, /c/ or /d/.:

Code Block
cd /afs/slac/g/atlas/c c # for example RHEL5-32bit(or d)

     Makes sure there is enough space with " fs lq * ".
     There are 17 more AFS partitions mounted, in addition to the /c/ partition.
     If more space is needed, send a request to unix-admin@slac.stanford.edu      (All examples below will assume installation in /c/)
---------------------------------------------------------------

3) Installing base release: x.x.x
Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log:

Code Block

pacman -allow any-platform trust-all-caches tar-overwrite -get http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/projects/cache:AtlasProduction_1516_6_56_i686_slc5_gcc43_opt>> pacman.log &

...

opt

4) Installing AtlasProduction cache: x.x.x.x
After steps 1-3, setup the release:

Code Block
. ~/reldirs/15.6.6/cmthome/setup.sh -tag=15asetup 16.6.6,32

Issue the pacman command found in the HN/e-news announcement, and direct to pacman.log. For examplethen setup the release for cmt:

Code Block
pacman -get http://cern.ch/atlas-computing/links/kitsDirectory/Production/cache:AtlasProduction_1516_6_56_12_i686_slc5_gcc43_opt >> pacman.log &

Note1: After the install is finished,

Code Block
cd /afs/slac/g/atlas/c/AtlasProduction/1516.6.56.12/AtlasProductionRunTime/cmt/ cmt config

    Note2: If the AtlasProduction package requires a new DBRelease, it has to be downloaded manually.
           Check the status of the Production cache in the corresponding web page,
           http://atlas-computing.web.cern.ch/atlas-computing/projects/releases/status/15.6.5.1/AtlasProduction/
           which usually lists the DBRelease version number.
           If it uses a new DBRelease version, scp the tar file over from lxplus.cern.ch and
           put it in /c/DBRelease/ and "tar -xf" and move it as the way others are.
           DBRelease tar files are stored in
           /afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/
   This script will do all the work:

Code Block


#
#get_dbrelease_from_cern.sh, by Andy Haas (SLAC)
#Takes one argument: the DBRelease version, i.e. "9.1.2"
#

cd /afs/slac/g/atlas/c/DBRelease

ssh lxplus.cern.ch "~/bin/bbcp -s 64 -P 2 -f /afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/DBRelease-${1}.tar.gz noric09.slac.stanford.edu:/afs/slac/g/atlas/c/DBRelease/"
#scp lxplus.cern.ch:/afs/cern.ch/atlas/www/GROUPS/DATABASE/pacman4/DBRelease/DBRelease-${1}.tar.gz .

tar -xzf DBRelease-${1}.tar.gz
mv -i DBRelease/${1} .
rm DBRelease/current
rmdir DBRelease
rm DBRelease-${1}.tar.gz

rm current
ln -s ${1} current

...

 ; cmt config ; cd -

5) Problems with release install
     Check the postings in https://groups.cern.ch/group/hn-atlas-releaseKitProblem/default.aspx
     as others might have similar problems.

     Ask Peter or Zach.
     If all fails, start a new thread in that forum.

pacman documentation : http://atlas.bu.edu/~youssef/pacman/

If you ran out of disk space during an install, manually download the last missing tarball with a command like:

Code Block
wget http://atlas-computing.web.cern.ch/atlas-computing/links/kitsDirectory/projects/kits/AtlasAnalysis_16_5_0_i686_slc5_gcc43_opt.tar.gz

6) When there is an announcement of new AtlasLogin or AtlasSettings
Go to the install area (/c/ in this example) and execute:

...

They are supposed to be backward compatible, unless stated otherwise. ----------------------------------------------------------------------------

7) Updating pacman:
There are usually ATLAS announcements asking to install a new version.
New version of pacman can be downloaded from BU.:

Code Block

...


wget http://physics.bu.edu/pacman/sample_cache/tarballs/pacman-latest.tar.gz

...


tar -xf pacman-latest.tar.gz

Move the pacman package to /afs/slac/g/atlas/packages/pacman/, go into the new
pacman directory and set up.

Code Block

...


cd x.xx

...


source setup.sh

         (Please note that any installs in /c/ or /d/ must stay with the pacman version
     that was originally used. pacman does not get updated often, but when it does
     it might be a good time to build a new install with it switching between
     /c/ and /d/.)

8) Installing manually a DBrelease: check here for what's available

Code Block
pacman -allow trust-all-caches -get http://atlas.web.cern.ch/Atlas/GROUPS/DATABASE/pacman4/DBRelease:DBRelease-${DBRELEASE_VERSION

This page has more info

9) Removing a release: (NEVER just use "rm -rf ..." - you'll confuse pacman!)

Code Block
pacman -remove AtlasProduction_16_0_2_3_i686_slc5_gcc43_opt pacman -remove AtlasProduction_16_0_2_i686_slc5_gcc43_opt
