This has been asked before unfortunately I do not think it is possible to do exactly what you want. You can have many different instances of perl DBI and DBD of course 1 for each server. By the way you would be much better off posting your question to dbi-users@perl.org (you don't need to subscribe in order to post, and you won't be automatically subscribed either as very few people use this form for dbi or driver support. dbi-users is where you'll get the best support.
