I want advice for old DOS app on Windows PC, that I need to make on 2 PC-s
fault tolerant. Any advice for working solution on FreeBSD?
Yep...rewrite the database in SQL with a PHP front end. Import the data
from the old system. Use a Radware/F5 Load Balancer for the web and
Slony-I for the database replication.
Welcome to 2008.
and have all "modern apps" problems and 1000 times higher hardware
requirements to do the same. my CA-Clipper apps running under DOS
are still in use after 15 years, because it work well. there is no
better language for such things, there are CA-Clipper ports for
unix, but not very good.
clip (ports/databases/clip) is an exception, except it's
screen handling is quite a mess.
but will a little of work it's good, i ported few program to clip.
clip is 5-20 times faster on the same machine than CA-Clipper :)
for now - i don't know anything better to write database-processing
programs than this. no "database engines" and other strange things -
fortunately.
it uses "ancient" technology - simply stores tables as flat files, and
indexes as other files.
there is quite a big chance this old DOS program was written in
CA-Clipper.
