I need to know how to determine the limits for number of processes
and messages on the RS6000 under AIX.  I would like to know this
for the system as a whole and for each user.  Also, how many child
processes a process can have?  And if theres a user limit, does it
apply to each of several logins or the aggregrate of all processes
under all logins of a user?

I prowled around in smit and Info but had no luck.

thanks for your help

Oh. Does anyone know how to get Info to tell what (paper) manual to
look in to find the material being displayed on the screen?

I don't know what you mean by limits on "messages".  AIX limits
the number of processes each user may have running concurrently.
I believe this limit applies to the aggregate total of all processes
started from all logins for any given uid.
You can view the logical device sys0 to see the current limit:
    lsattr -l sys0 -E
and you can use chdev to change it.  For instance:
    chdev -l sys0 -a maxuproc=100

I don't think SMIT allows you to change this limit.  Incidentally,
this information is in /usr/lpp/bos/README.

I don't know what the system process limit is, if any.
