UPS HINTS

Fermi RedHat Linux 5.n vs 6.n

1. Making sure you get Linux+2 (FRH5.2) rather than Linux+2.2 (FRH6.1) version of Fermilab products:

      upd install -H Linux+2.0 <product> <version>
   

   tells ups to ignore what the OS tells it and pretend it has a version of the kernal that is compatible with FRH5.2.
2. Restoring an old version of ups when you've hosed the "current" version:

   1) cd to the old ups product directory
   2) set UPS_DIR to the current directory
        UPS_DIR=`pwd`; export UPS_DIR
      or
        setenv UPS_DIR $cwd
   3) source the ups/setup.{csh,sh} file
        . ups/setup.sh
      or
        source ups/setup.csh
   
   You now have the old version setup, and you can do the ups declare
   to make the old version current again.
