re: increase of shared memory to 512 MB on lab2 subnet machines
>John is gone until Monday.  I'll try to update the config for shared memory

OK, I'll be around if you have any questions.  The web page I cited
in a previous email has the procedure necessary to modify shared memory
on Sun Solaris machines, so I don't think my input will be needed.

>How many machines need to run McIDAS-X?

I am assuming that Elen will be using most/all of the machines in the
lab come fall semester.

This would probably be a good idea.

Again, the change in shared memory configuration does not impact the
machines unless someone tries to use it.  If you want to be totally
on the save side (probably not necessary), you could increase shared
memory to the combined size of RAM and swap.

re: ADDE remote server user, 'mcadde'

>We don't create accounts that share the same userid.

The user id is different; the home directory is the same.

>It causes too many

OK, this should work.

>The accounts for mcidas,

Right.  I should have said that explicitly.

Thanks for the help.  I am sure that Elen will be most appreciative.

I will include you on my email to John T. about the things that need
to be done as 'root' for the LDM installation.
