[BangPypers] ORA-12705: Cannot access NLS data files or invalid environment specified

[Wah Meng Wong]

Hello there,

My oracledb module on HP-UX is unable to connect to database when I export 
environment variable NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK". There is no 
issue when such environment variable is exported and the SQLPLUS is issued. The 
DBA determined that this is an application error. Does anyone know this might be 
related to the some national language library not properly installed on the 
server? I noticed that there is no $ORACLE_HOME/ocommon folder on my server 
where Oracle installed is 11g, and I googled that environemnt variable ORA_NLS33 
by default is pointing to $ORACLE_HOME/ocommon/nls/admin/data. Or ORA_NLS33 is 
no longer in use for Oracle 11g?
