Anyone seen anything like this before?
User is locked, but lock date is null
SQL> select username, account_status, lock_date
2 from dba_users
3 where account_status like 'LOCK%';
USERNAME ACCOUNT_ST LOCK_DATE
-------------------- ---------- -----------
<snip other users>
MYAPPUSER LOCKED
15 rows selected.
Account has locked multiple times today. Notice status is simply LOCKED, not LOCKED(TIMED) as it would be if wrong password entered too many times.
