4795.0. "Enabled Alarm -- system resouce required?" by HKGACT::SUSANCHAN () Thu Apr 01 1993 06:51

What is the memory, pagefile quota require for each enabled ALARM rules on
V1.2/V13?

There is a requirement on V1.1, is the same apply for V1.2/V1.3 or more is
required?  Any experience in the field?

It varies depending on the MMs invoked by the rule.
For example: if you create an alarm rule on a STATISTIC, then you
(transparently) use the services of the 
	1. the PA FM (gets called once for each statistic)
	2. the AM called by the PA FM (gets called twice for ea statistic)

Different MMs use different amounts of memory.

If you can give a more *specific* example, then it's a fairly straightforward
exercise to empirically determine how much memory each rule consumes.

If there are so many variants on the memory usage for different MM,
why it isn't documented?  At least a guideline?!

This is being asked by customer.  In the manual, it only recommended a
separate account for ALARM enabling, but it doesn't give any idea of what
the process quota for the account.  There is a very high chance of system 
hang/crash because of insufficient resource (which I had experience before
and I have to perform system monitoring to find out ALARMS eat up a lot
of memory).  

It is wiser to have the user to set up a workable environment at the very
beginning.

4795.3where would you document itTOOK::CALLANDERMCC = My Constant CompanionTue Apr 27 1993 15:1910
    where and how do you think it should be documented?
    
    I am not be sarcastic, I really am interested in knowing how would you
    want to see it documented. End user documentation? a quick cheat sheet
    for the support center? A procedure you run and it gives you a hit
    about what it thinks you might need? The alarm manager includes an
    estimate in the templates?
    
    other ideas?
    
4795.4TRy running the config toolRACER::daveAhh, but fortunately, I have the key to escape reality.Tue Apr 27 1993 17:534
You could also run the configuration tool and see what it says the requirements
are.  Its real close on lots of things....
