Hi,
Looking for wait events and locks monitoring /resolving scriptsHere is the collection of monitoring scripts that I
use, and it has dozens of scripts for locking:

For one-off scripts, here is a script by Laurent Baylac to show locks in Oracle 10g:

SET LINESIZE 500
SET PAGESIZE 1000
COLUMN username FORMAT A15
COLUMN machine FORMAT A25
COLUMN logon_time FORMAT A20
SELECT LPAD(' ', (level-1)*2, ' ') || NVL(s.username, '(oracle)') AS username,
s.osuser,
s.sid,
s.serial#,
s.lockwait,
s.status,
s.module,
s.machine,
s.program,
TO_CHAR(s.logon_Time,'DD-MON-YYYY HH24:MI:SS') AS logon_time
FROM v$session s
CONNECT BY PRIOR s.sid = s.blocking_session
START WITH s.blocking_session IS NULL;
SET PAGESIZE 14
-- Search for locked objects
-- To be executed under the SYSTEM account
-- Compatible with Oracle10.1.x and higher
select
distinct to_name object_locked
from
v$object_dependency
where
to_address in
select /*+ ordered */
w.kgllkhdl address
from
dba_kgllock w,
dba_kgllock h,
v$session w1,
v$session h1
where
(((h.kgllkmod != 0) and (h.kgllkmod != 1)
and ((h.kgllkreq = 0) or (h.kgllkreq = 1)))
and
(((w.kgllkmod = 0) or (w.kgllkmod= 1))
and ((w.kgllkreq != 0) and (w.kgllkreq != 1))))
and w.kgllktype = h.kgllktype
and w.kgllkhdl = h.kgllkhdl
and w.kgllkuse = w1.saddr
and h.kgllkuse = h1.saddr
