Clint,

OK, I logged back on and verified that I could do simple things in
McIDAS.  Now, we need to setup the shared memory so that McIDAS sessions
and multiple invocations of ADDE servers can run.

I offer the following additions that Mike Schmidt makes on our
Solaris 2.x systems:

* xntpd on Solaris
*
set dosynctodr=0

*
* performance tuning 
*     see SMCC NFS Server Performance and Tuning Guide (Solaris 2.5.1)
*
set ncsize=5000

*
* NFS accepts connections from privileged programs only
*     for Solaris 2.5+ only - see nfsd manual page
*
set nfssrv:nfs_portmon = 1

*
* performance tuning shared mamory system
*     for mcidas and others - see Solaris 2.5 Sys Admin Guide, page 1282
*
set shmsys:shminfo_shmmax = 268435456
set semsys:seminfo_semmap = 250
set semsys:seminfo_semmni = 500
set semsys:seminfo_semmns = 500
set semsys:seminfo_semmsl = 500
set semsys:seminfo_semmnu = 500
set semsys:seminfo_semume = 100
set shmsys:shminfo_shmmin = 200
set shmsys:shminfo_shmmni = 200
set shmsys:shminfo_shmseg = 200

*
* InfoDoc 18437 - Solaris Executable User Stacks
*
set noexec_user_stack=1

After this change is made, the system will need another reboot.
