BIRD -- ZSH environment problems
Some settings in your .zshrc can influence the operation of the BIRD environment setup script /usr/sge/default/common/settings.sh
If you cannot start qmon because of a missing library or qstat exits with error, you .zshrc could be the reason. To test if that is the case add
if [ ! "$HOST" = lc3 -a ! "$HOST" = lc4 ]; then
as very first line and
else echo " logged into batch cluster submit host --> ignored .zshrc" fi
as very last lines in your ~/.zshrc
After this modification you should see the line "logged into batch cluster submit host --> ignored .zshrc" when logging into the cluster.
After freshly logging into lc3 or lc4 execute
again and see if qmon and qstat work. If it does work now, your custom settings have been the problem.
