Grouper Users - Open Discussion List

[Tom Zeller <>]

Which database (oracle, mysql, postgres, ...) on what platform (linux,
windows) ?

What order of magnitude is "multiple" (tens, hundreds, thousands) ?

Are your interactions multithreaded in java ? Meaning multiple threads
(interactions) in a single jvm connect to  one grouper database ?

Just trying to understand the environment.
