OS Authentication in Oracle OPS$

Question

I'm trying to use this command to be able to login in sqlplus directly(without inputting username and password)

sqlplus /@db_name

but i'm experiencing this error

ORA-01017: invalid username/password; logon denied

i granted to an OPS$ user

GRANT CONNECT TO ops$user;

Answer 1

OK, as database is on local machine, you shouldn't have to use @db_name, "sqlplus /" should work fine - just ensure that environment variable ORACLE_SID is setup correctly. Note please ensure that when creating user you specified "IDENTIFIED EXTERNALLY". Note you have to be logged in to machine as "user"; I recall if on Windows may also need domain as part of Oracle username.

Answer 2

This is the script I use to login as an os authenticated user. Please pay attention to the init setting "os_authent_prefix". If it is set to "OPS$" and you want to keep it that way, you will have to modify the script so the username you create is prefixed by "OPS$".

Best of luck!
