Top DB2 LUW Performance FAQs, Part 2

Show Host Scott Hayes Commentary
Steve Rees has been with IBM for over 22 years and has worked on DB2 for LUW performance for the past 15 of those years. I was taking notes as fast as I could, and I'll be watching this replay! You can't watch this replay and NOT learn something! I was particularly impressed by discussion of monreport.dbsummary, monreport.pkgcache, monreport.currentsql, monreport.connection, monreport.lockwait, and monreport.currentapps. Also, Steve's insights on when to use, and when NOT to use, the DB2 Statement Concentrator (STMT_CONC) were quite insightful.

BONUS MATERIAL!
During the show, Steve shared with us his "magic" SQL for listing all of the available monitor table functions and administrative views from DB2's catalog. Here's the SQL:
select
substr(P.ROUTINENAME,1,32) as ROUTINENAME,
substr(P.SPECIFICNAME,1,32) as SPECIFICNAME,
case when P.ROWTYPE in ('B','O','P') then CHAR('IN',3)
else CHAR('OUT',3) end as IN_OUT,
cast(p.ORDINAL as char(3)) as ORD,
substr(P.PARMNAME,1,40) as PARMNAME,
substr(P.TYPENAME,1,16) as TYPE
from sysibm.sysroutines r, sysibm.sysroutineparms p
where p.routineschema=r.routineschema
and p.routinename=r.routinename
and p.specificname=r.specificname
and r.function_type='T'
and substr(r.ROUTINENAME,1,4) in ('SNAP','MON_','ENV_')
order by P.ROUTINESCHEMA,
P.ROUTINENAME,
P.SPECIFICNAME,
IN_OUT,
P.ORDINAL
