Hi,

We are using Oracle 9i(RAC) on linux

I am constantly observing 'row cache lock' and 'KJC: Wait for msg sends to complete null'in v$session_wait.

The session observed is stalling and consuming 95% CPU all the time

I have mentioed the records in v$session_wait, V$lock and V$rowcache.

Can anybody help me identifiing the problem

Thanks and Regards,
OraSaket

Hi,

The query stalling and assoicated plan is as mentioned below

select   lcpedseq, dtbeneff, dtbenexp, dtclaimfrmyr, dtclaimtoyr, nstatus
FROM     cl
WHERE    strpolnbr = :b
AND      (   dtbeneff <= :b1
          OR :b1 IS NULL 
		  )
AND      nstatus <> 2
ORDER BY dtbeneff DESC,
         dtbenexp DESC,
         dtcreated DESC


Execution Plan
----------------------------------------------------------
   0      SELECT STATEMENT Optimizer=CHOOSE (Cost=14 Card=3 Bytes=174)
   1    0   SORT (ORDER BY) (Cost=14 Card=3 Bytes=174)
   2    1     TABLE ACCESS (BY INDEX ROWID) OF C
          L' (Cost=13 Card=3 Bytes=174)

   3    2       INDEX (RANGE SCAN) OF 'INDX_POLNBR_CPED_IDX' (NON-UNIQ
          UE) (Cost=4 Card=36)
