Re: export AIXTHREAD_MNRATIO=1:1 : needed or not ?

Speaking as a former support person... when troubleshooting complex
problems, I have often asked customers to try things that might or might
not make any difference. It wasn't a matter "humoring me" or creating
"busy work" for the customer. Rather, it was a systematic process of
elimination: something that doesn't make a difference can still help
narrow the scope of the problem by eliminating places where you don't have
to look.

With that said... I am not familiar with the particulars of the issue
described in this thread, but I would think it fair to expect the support
person to elaborate on why he is recommending a course of action that the
documentation suggests is unnecessary.

It actually doesn't matter whether it'll help or not.  The rule is "Always
humor the support people or they get snippy."  I recommend taking a deep
breath, doing it, and then telling them it didn't help.  Err, unless it
does
help.

Hi *SM'ers,

A quickie one : we're actually facing severe performance problems, log
filling at the speed of light etc etc, so we opened a PMR at IBM, and one
of
the first advises I got was to add following lines in  rc.adsmserv. :
export AIXTHREAD_MNRATIO=1:1
export AIXTHREAD_SCOPE=S

We are actually under AIX 3.3.3.0, using TSM server 4.2.3.1. My question
is
: do I really have to implement those lines, as the header of rc.adsmserv
that was installed automatically specifies :

# 04/11/2001 rmf:No_MNRATIO:export AIXTHREAD* no longer required.
#                break links with tsm410s.lanfree and tsm420s.beta

So, what do you think ?
Thanks in advance.

Arnaud
