To make matters worse, the process is completely hung now, being 100% CPU
bound with zero I/O:

=====================
PARSING IN CURSOR #33 len=761 dep=1 uid=105 oct=2 lid=105 tim=952209474
hv=1784939705 ad='e6f44c20'
INSERT INTO part_usage_tmp
SELECT
ph.partno
, DECODE(ph.warehouse,:"SYS_B_00",:"SYS_B_01",NULL,:"SYS_B_02",
ph.warehouse) warehouse
, ph.transqty
FROM
QT_PART_HISTORY_24_MONTHS ph
, glxref gl
WHERE
ph.ACCOUNTNO = gl.ACCOUNTNO
AND gl.ENTITY_CODE = :"SYS_B_03"
AND ph.fiscal_year BETWEEN :"SYS_B_04" AND 
TO_NUMBER(TO_CHAR(TRUNC(SYSDATE), :"SYS_B_05"))
AND TO_DATE(SUBSTR(TIME_STAMP,:"SYS_B_06",:"SYS_B_07"),:"SYS_B_08") BETWEEN 
:"SYS_B_09" AND LAST_DAY(ADD_MONTHS(TRUNC(SYSDATE),-:"SYS_B_10"))
AND ph.transtype IN (:"SYS_B_11",:"SYS_B_12",:"SYS_B_13")
AND gl.PRICELISTNO LIKE :"SYS_B_14"
END OF STMT
PARSE #33:c=0,e=0,p=0,cr=0,cu=0,mis=1,r=0,dep=1,og=0,tim=952209474

It's been sitting here now for 15 minutes (more?) in a tight CPU loop.

Joy.
