Hi All,

ORA-00604 : error occured at recursive SQL level 1

I searched on internet and found below solutions but both of them are not working for me ; Please help asap.

1. Set timezone in docket file as below
ENV TZ=America/New_York
2. Also setup timezone to open oracle connection as below
Oracle globalization info = con.GetSession();

con.SetSessionInfo(info);
