Set locale for oracle

[belka0107]

I'm trying to connect to oracle, but get error:

ORA-00604: error occurred at recursive SQL level 1 ORA-12705: Cannot access NLS data files or invalid environment specified

In sqldeveloper I can fix it if define -Duser.region=US. Where I can set thisoption for jasper server?

This is a JasperReports forum. Your question has nothing to do with JasperReports but only on setting up Oracle database. It's better to ask Oracle questions at Oracle forum or at Stackoverflow.

I have solved the problem changing the language of my iReport (or TIBCO jaspersoft) tool in the same of that my database. 
For check try this:

select DECODE(parameter, 'NLS_CHARACTERSET', 'CHARACTER SET','NLS_LANGUAGE', 'LANGUAGE','NLS_TERRITORY', 'TERRITORY') name,value from v$nls_parametersWHERE parameter IN ( 'NLS_CHARACTERSET', 'NLS_LANGUAGE', 'NLS_TERRITORY')[/code]
