为没有密码（空）的用户连接Oracle`sqlplus`

Question

It seems that sqlplus does not do will with an empty (null) password.

THIS WORKS: sqlplus user1/passpass@DBB
THIS DOES NOT WORK: sqlplus user2/@DBB

From what I can tell, it appears that sqlplus does not like an empty (null) password. Is there a workaround for this?

NB: This is not just a question about avoiding putting the password in plain-text on the sqlplus command line.

Answer 1

sqlplus user2@DBB

then you will be prompted for a password

Did you use either of these?:

• Oracle valet. User is identified via password, but the password is not prompted manually.
• External authentication. CREATE USER XY IDENTIFIED EXTERNALLY; The user XY must then have OS account on the DB server.

the user should be automatically validated without password in these cases.
