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. Pedro. > cheers, > Danny Thomas <D.Thomas@vthrc.uq.edu.au>
