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:

...

:

...

RHEL5-32 bit:  built on atlas-prod05.slac.stanford.edu:

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/.:

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:

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:

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

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

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,

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:

pacman trust-all-caches -get http://atlas.web.cern.ch/Atlas/GROUPS/DATABASE/pacman4/DBRelease:DBRelease-current

    See https://twiki.cern.ch/twiki/bin/viewauth/Atlas/AtlasDBRelease

 ; 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:

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

...

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

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!)

pacman -remove AtlasProduction_16_0_2_3_i686_slc5_gcc43_opt
pacman -remove AtlasProduction_16_0_2_i686_slc5_gcc43_opt
