Re: Collecting Stats for PMAM Reports

Discussion created by ca.portal.admin on Jul 20, 2005
STATISTICS INTERVAL OFF NOLINE TASK WRITE NOUSER TRANSACTION ?

You don't need the ""WRITE"" component for PerfMon - ""COLLECT"" is all that
is
required. ""WRITE"" causes stats to be written to the DC Log which can
cause
performance issues. ""COLLECT"" just accumulates the stats in control
blocks
which PerfMon will then deal with according to your settings in the
#PMOPT
macro. In #PMOPT you can direct the stats to the Log or SMF. For
performance
reasons of course SMF is recommended - avoid the Log.

TRANSACTION/NOTRANSACTION is interesting - I don't think that there's
any
cost for having it set. What it lets you do is a BIND TRANSACTION
STATISTICS
to initiate collection of stats for a ""transaction"" that can span
multiple
tasks - then you can do an ACCEPT TRANSACTION STATISTICS to get these
stats
- and finally an END TRANSACTION STATISTICS to end the collection. This
would be useful for determining the total cost of a ""business
transaction""
that spans multiple ADS/Cobol screens for example. I have never seen
anybody
use this - but the functionality is there. I note from the sysgen manual
that TRANSACTION is required for ADS statistics to be enabled.

Back to the original question - it's the TASK COLLECT/ TASK WRITE /
NOTASK
option that affects PerfMon. With NOTASK PerfMon will not be able give
you
any information at all. I think a look at the PerfMon Administration
manual
would be advised - as I have not followed my own advice to many people
which
is to read the manual - so the information in this e-mail may be
contaminated by the odd ""elderly moment"" or two. ;-)

HTH - cheers - Gary
