To achieve full performance, I read that it better to tie the berkeleyDB once and reuse the handle for each request, i.e. having the tie command outside of the mod_perl handler.
Yes. If you really are concerned with performance, don't use the tie API at all. Use the OO methods (get, put) directly.
Has someone example code to do that?
If this is read/write, you need to use the BerkeleyDB::Env stuff. If you google a little you should find some examples. I know I've put a few here and on perlmonks.org.
I can imagine how to tie on startup, but how to trigger the code for untie at shutdown? Is untie needed at all with berkeleyDB?
Yes, do the untie to flush buffers to disk. The appropriate place to do this is the PerlChildInitHandler and PerlChildExitHandler. Do not try to open it in the parent process. - Perrin
