  13. site-info.def(1)‏ • Be careful the variable format, that is: <variable>=<your parameter>. Please don't give any space at the line. e.g. CE_HOST=myce.mydomain that is correct. e.g. CE_HOST = myce.mydomain that is wrong format. • Must be careful the JAVA_LOCATION variable, that should be match to your java jdk version.

  19. 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 /gLite cd /gLite tar zxvf glite-UI-3.1.8-0.tar.gz tar zxvf glite-UI-3.1.8-0-external.tar.gz

  20. Configuration • When you are already untar the tarball, just run the configure command: <INSTALL_ROOT>/glite/yaim/bin/yaim -c -s <your site-info.def> -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
