Dianna, To use auditing you will need to set the init parameter Audit_trail=DB (or file) Then set auditing on: Audit session whenever not successful; The output from failed connections can be seen in dba_audit_session. You need to be careful regarding the growth of the underlying table SYS.AUD$, which is in the system tablespace by default. There is a MOS article about moving it to a separate tablespace. Turn off the auditing using the noaudit command.
