Hi all,
I got the following error while trying to connect to remote DB with a script:

ORA-28000: the account is locked

How do I investigate what caused this lock ?

I can only think of 2 ways an account gets locked.
1) Somebody manually issued SQL to LOCK the account.
2) there were repeated login failures & Oracle locked the account to prevent hacker from breaking into this account.

If the connection requests originated from a remote client over SQL*Net, then listener.log file will show ACCOUNT_NAME in it.

ORA-28000: the account is locked
 *Cause:   The user has entered wrong password consequently for maximum
           number of times specified by the user's profile parameter
           FAILED_LOGIN_ATTEMPTS, or the DBA has locked the account
 *Action:  Wait for PASSWORD_LOCK_TIME or contact DBA

You can check if this is one case or the other one with the status of the account in DBA_USERS.
If it is the case of "ALTER USER ACCOUNT LOCK" then the status is like "%LOCKED".
If it is the case of bad logins then the status is like "%LOCKED(TIMED)".

Also, since it hasn't been mentioned... If you are using OS Authentication, your OS user may be locked out. You'd need to talk to the Sys Admin to see how and why it happened.

If audit is enabled , then you can query from dba_audit_trail to find the culprit.

OP last logged onto this forum 2 April so likely won't benefit from advice above any time in the near future.
