Is that the case or did I miss it ? in case SCO emulation does exist, my real question follows howdie, our library has got a serious problem with the client-server system it uses to provide campus-wide access to databases, mostly off CDROM. Currently they are running the SCO version of ERL (www.silverplatter.com) which doesn't seem to handle the increasing load very well. The library people don't have much unix experience, but at the direction of the ERL distributors have tweaked various OS parameters to no avail. Of course the problem could be within ERL, but I'm wondering whether it's worth their while trying to run the server software on another UNIX offering SCO emulation. In the first instance of trying to interest the library enough to explore this possibility, I'm trying to convey that UNIX emulation doesn't bear the overheads or complexity of projects like WINE, WABI, SoftPC, etc. I'm looking for informed comments on whether SCO emulation 1) is likely to work, ie what might cause problems 2) whether running under FreeBSD is likely to cope better with the load. Is SCO known to poorly cope with various definitions of "heavy load" ? This is a serious immediate issue for the library, but the ERL distributors haven't been able to say that throwing extra money at the servers will improve the situation. SilverPlatter are also developing Linux & NT versions of the server, but the situation needs to be fixed now. cheers, Danny Thomas From owner-freebsd-emulation Tue Apr 8 09:03:14 1997 Return-Path: Received: (from root@localhost) by freefall.freebsd.org (8.8.5/8.8.5) id JAA15375 for emulation-outgoing; Tue, 8 Apr 1997 09:03:14 -0700 (PDT) Received: from ingenieria ([168.176.15.11]) by freefall.freebsd.org (8.8.5/8.8.5) with SMTP id JAA15351 for ; Tue, 8 Apr 1997 09:03:00 -0700 (PDT) Received: from unalmodem.usc.unal.edu.co by ingenieria (SMI-8.6/SMI-SVR4) id LAA00009; Tue, 8 Apr 1997 11:48:14 -0400 Message-ID: <334A7D3E.540@fps.biblos.unal.edu.co> Date: Tue, 08 Apr 1997 10:15:42 -0700 From: Pedro Giffuni X-Mailer: Mozilla 3.0 (Win16; I) MIME-Version: 1.0 To: Danny Thomas CC: freebsd-emulation@freebsd.org Subject: Re: SCO emulation References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-emulation@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Danny Thomas wrote: > > in case SCO emulation does exist, my real question follows > Yes, SCO emulation does exist, you activate it in /etc/sysconfig . > howdie, our library has got a serious problem with the client-server system > it uses to provide campus-wide access to databases, mostly off CDROM. > Currently they are running the SCO version of ERL (www.silverplatter.com) > which doesn't seem to handle the increasing load very well.

I was thinking in using the software you mention, but I never took the time. Furthermore, I was going to ask them to pack their software in amore conventional (tar.gz) format. My opinion is: 1) SCO does fail under heavy load because their old compiler in their old versions was developed by Microsoft :-). They also have this policy of limiting the number of users and build their kernels accordingly. 2) As a general rule FreeBSD is faster (even when emulating) and as stable. SCO's emulation has improved in the latest release, but it didn't give me problems using ISIS for Unix with 2.1.5. 3) In your particular case, you can combine the SCO ERL server with the Linux http gateway because we also emulate Linux. > This is a serious immediate issue for the library, but the ERL distributors > haven't been able to say that throwing extra money at the servers will > improve the situation.

We are working with ISIS and ISIS-freeWAIS around here but it has not been an urgent issue. Give ERL a try, it should work, specially if you can grab some SCO shared libraries that might be needed (I don't know which, but since you have an SCO box you can find out). FreeBSD is definitely better.

I hope this port helps to further test our SCO emulation. Special thanks to Erich Hernes who gave some finishing touches and committed the port. As a curiosity if the target is changed to i386-sco3.2v5elf we may also generate SCO's ELFs, but this is untested, it doesn't seem to be used by anyone (not even by SCO), and we don't emulate it (yet ?). --Pedro.
