Can anybody point me to papers on how we review whether our HP3000s are
suffering from memory shortages.  

Scenario : Over the last few months,  we have had some performance
problems on our production HP3000 - usually at month end.  By very basic
observation in Glance we have come to the "conclusion" that certain
programs are draining the system's memory so that transactions that
would normally take a few seconds to run can take up to one minute to
run. 

Whilst we have ordered more memory as a short term fix (it's so cheap it
really is a no-brainer),  I'm wondering what others use to review the
memory of their programs.    For example,  can you confirm how much
memory is being pre-allocated as a program is loaded by the run
statement ? 

I've certainly noticed that certain programs do appear to trigger the
performance problems - and they all seem to have large Working storage
tables - I demonstrated to my colleagues that by converting working
storage tables to KSAM files you can improve the performance of a
program - it also has the additional benefit that the application then
doesn't demand so much memory.    Many years ago (pre native mode
machines) I worked at one company where the HP3000 ran fine until one
particular application was loaded - even if that application wasn't
using CPU,  the machine ground to a halt !

Btw - the number of users connected to our HP3000 grew as a result of a
merger - however, the system copes reasonably well most days, which is
why I think the problem is mainly related to specific applications.
