... I am just learning about this, but my initial inquiries suggest that the only way to achieve true concurrency using a language like python is to launch multiple interpreters.
This is true when you mean by "true concurrency" "can keep a multi-CPU systems busy". One a single CPU system, you get almost the concurrency which is possible (modulo bugs such as holding the GIL during non Python related possible expensive operations).
I don't yet have the solution to my problem, but at least now I know what the problem is, and that is half the battle.
One option is to fix the Sybase access module, another one to use SQLRelay, a third one to access the Sybase database via ODBC.
4-th option is to use MSSQL DA with threads, it use sybase as database server (and file "interfaces" as redirector to other MSSQL/sybase DB). It works very well. It is quite old, but it works with 2.9.4 too (newer Zope server I does not use). http://zope.org/Members/thinmanj74/Z%20MS%20SQL%20Database%20Adapterhttp://w... http://mail.zope.org/pipermail/zope-db/2004-May/003067.html Regards, JL.
