ORA-1017: invalid username/password; logon denied

Hi,

When we are opening an Oracle connection with Oracle 11g using Oracle.DataAccess.Client. “ORA-1017: invalid username/password; logon denied” error may occur.

This is due to oracle case sensitivity rule in Oracle 11g.

Solution:-

Run following command

ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE

Happy Programing..
