Strange behaviour : php accessing Oracle (PLS-00553: character set name)

Hi, Ie developed some scripts to access oracle. Using my development machine it works great. When I switch to the production server I keep getting Warning: OCIStmtExecute: ORA-06550: line 3, column 33: PLS-00553: character set name is not recognized ORA-06550: line 0, column 0: PL/SQL: Compilation unit analysis terminated in /var/www/html/test.php on line 35 This only happens with stored procedures. Regular selects work fine. Since the same production server is used by many delphi applications I may be doing something wrong. Any tips will be appreciated. If this is considered off-topic please email me directly. Regards, __________________________________________________ Do You Yahoo!? Got something to say? Say it better with Yahoo!
