It pays to read the documentation

Had an issue where I couldn't get forms builder to work.

Here's the error code:

# frmbld
FRM-91111: Internal Error: window system startup failure.
FRM-10039: Unable to start up the Form Builder.

It should work right out of the box, looks like the build config had changed much, here's the env file used:

ORACLE_HOME=/u01/app/oracle/product/ias10gds
export ORACLE_HOME
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/jdk/jre/lib/sparc:$ORACLE_HOME/jdk/jre/lib/sparc/native_threads
export LD_LIBRARY_PATH
PATH=$ORACLE_HOME/bin:$ORACLE_HOME/opmn/bin:/usr/local/bin:/usr/ccs/bin:/bin:/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/usr/ucb:/usr/ccs/bin:/usr/sbin:/usr/X/bin:$ORACLE_HOME/OPatch
export PATH
FORMS_PATH=/u01/app/sct/baninbr2/QUAL/forms/fmb
export FORMS_PATH

Eventually found this documentation post about how to solve the problem. Basically since the last time we used forms builder on this server, the other Oracle homes required a change to NLS_LANG with a UTF8 characterset.

Simply added the following to the above forms builder env file fixed the issue with forms builder:

export NLS_LANG=

Problem solved.
