There has been one regular release since then (15OCT99) and the "AIPS for
the Ages" version 31DEC99 is also available; see www.cv.nrao.edu/aips/ for
details.

This is most likely because:

> Shared memory id failure: Invalid argument

Most likely this is answered in our Installer/Manager FAQ, available from
the above AIPS home page or at www.cv.nrao.edu/aips/aipsmgr/

     Shared memory id failure: Invalid Argument 

     If you see this when the system is trying to fire up the AIPS TV
     (XAS) on a Solaris system, then your X11 display does not support
     more than the default of 1 Megabyte maximum for shared memory
     segment. If your monitor displays 1280x1024 or larger, the sizes of
     the shared memory segments XAS wants will exceed a Megabyte.
     Solution: have your sysadmin edit /etc/system and put this line
     somewhere near the end:

         set shmsys:shminfo_shmmax=8388608

     While there, you may want to also add these if you have more than 64
     Mbytes of real memory:

         set ufs:ufs_HW=6291456
         set ufs:ufs_LW=4194304
         set priority_paging=1 

     Only add the last one if you are running Solaris 7 or later. These
     three settings will boost your overall AIPS performance.

You do not see them on the remote system because the display and XAS are
on different machines, and there is no attempt to have shared memory
between them.

You can try to install a subset.  I'd do the following:

    a) make sure the AIPS_ROOT area is visible from the non-ultra sparc
       systems.  Suppose this is /home/aips.
    b) cd to /home/aips on one of the sparc systems with a tape drive.
    c) Type "./INSTEP1" and go through the install; you're merely adding
       the details of the SOL architecture to your existing SUL
       installation now.
    d) Refuse the option to FTP the binaries (the 15APR99 binaries are
       long gone anyway; we only have 15OCT99 binaries available and you
       don't want to use those in a 15APR99 environment).
    e) When you're done, save the TPMON.EXE I'll send under separate cover
       to the /home/aips/15APR99/SOL/LOAD/ directory.  Make hard links to
       it: 
                cd /home/aips/15APR99/SOL/LOAD
                ln TPMON.EXE TPMON1
                ln TPMON.EXE TPMON2
       You need TPMON1 for FITS disk access, TPMON2 for tape drive 1,
       etc.  so if you have two tape drives on this system for AIPS to
       use, you'd also want to make a TPMON3 hard link.
    f) Edit HOSTS.LIST to add other tape/SOL machines.  Make them full
       AIPS hosts for now.
    g) run the SYSETUP shell script:
                $SYSUNIX/SYSETUP

I *think* this is all that's required.  The lesser sparc systems will not
be able to run AIPS itself, but this should set up enough for them to run
the TPMON daemons to serve the tape drives to other systems.

Be sure you have TPHOSTS (in /home/aips/DA00/) configured to only allow
connections from the appropriate range of IP hosts.  You don't want the
whole world to use your tape drives!
