SQL Delete question

[Dennis Munro <DMunro@xxxxxxxxxxxxxxxxxxxx>]

V5R1M0 fairly current on all group/cum ptf's

The PO processing in BPCS must have gone haywire one day because I had 2,
085,055 notes written for one given PO - possibly a P/C locked up but who
will remember what happened 10+ months ago.

When I go to delete them using SQL, I aborted the job after 35 minutes
because I just had no clue how long it would take plus I had to get home.
Looking at it today, I did get about 1,350,000 records deleted in that time
frame.  This was run on our test box which is a 720 & I was the only person
signed on at the time

 My production machine is an 820 with 35(???) interactive and I guess I am
making the assumption that STRSQL is a green screen/interactive job & what
would be a way to better delete this number of records?  The real problem is
the above scenario happened three times so I have 6,444,070 ESN records to
be deleted.  I would get killed if I ran that during the day with that kind
of performance hit.

Below is the SQL statement used & I am wondering is there something that
would "speed" up the process.  . 

<SNIP>
DELETE FROM BPCSF/ESN WHERE SNTYPE = 'P' and SNDESC =   
'Billing date: approx. 4/15/02 March 2002 usage'        
Z<SNIP>

Sure is a simple "program" to accomplish the job but what about performance?
We run 24x7 so letting the SQL statement run some weekend would impact the
least amount of users if that is the only option & I am not against doing
that???

Thanks - Dennis.
