Subject: Extremely slow querry

Hi All,

Peoplesoap database
Oracle 8.0.5
AIX 4.3.2

SELECT

    JOB.EMPLID,
    JOB.EMPL_RCD#,
    SEC.OPRCLASS,
    SEC.ACCESS_CD

FROM
PS_JOB JOB,
PS_FAST_SCRTY_2 SEC
WHERE

     SEC.ACCESS_CD =  'Y'
    AND     SEC.SETID = JOB.SETID_DEPT
    AND     SEC.DEPTID = JOB.DEPTID

****************

This is a select that is part of a PS view (stripped version) and takes 35 SECONDS NOT MINUTES
The explain plan shows just a nested loop with the smaller table (ps_fast_scrty_2 5500 records) as the driving table and the large table (180.000 records) is not even accessed, all needed information comes out of the index.

This is a small database on a machine that should be capable of a lot more.

Anybody any idea???
