    Talking SQL Hash Value

    From Enterprise Manager: Targets => Database

    Select database => Performance => Instance Locks => Blocking Locks

    Select: Session ID or SQL Hash Value

    Look at dba_blockers and dba_waiters. You can then look at v$sqlarea to find the sql being run via sql_id. v$session_longops might also be useful.

    Yes you do have OEM, in 9i you can install the EM database console from the 'client' installation CD or download. For 10g you just execute emca which you can find under the ?/bin diractoy (or install from the client sw).
