Oracle Forms Builder 11g R2 on Oracle Linux 6

If you want to run the Forms Builder utility (by executing the $INSTANCE_HOME/bin/frmbld.sh script) on your Oracle Linux 6 system, it is possible that you receive this error:

That's because you forgot something during your OS preparation.
In fact, you have to set the NLS_LANG environment variable for your user, e.g. in the .bash_profile file:
export NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P15

When you have this variable, you can run Forms Builder without any problem!
