Installation Download the two tarballs from the repository. Create an INSTALL_ROOT directory for the distribution. Then cd into this directory and untar both tarballs. As an example : mkdir /g. Lite cd /g. Lite tar zxvf glite-UI-3. 1. 8 -0. tar. gz tar zxvf glite-UI-3. 1. 8 -0 -external. tar. gz 23

Configuration When you are already untar the tarball, just run the configure command: /glite/yaim/bin/yaim -c -s -n UI_TAR To use the UI TAR you have to source one file (*. sh for bash, *csh for tcsh): $GLITE_EXTERNAL_ROOT/etc/profile. d/grid-env. (c)sh 24
