We use DBI connection pooling with postgres in mod_perl environment
and it works fine. We however do not use connect_on_init as Apache::DBI
docs say that all DBI->connect() anyway gets intercepted transparently.
please take care that
1. Make sure Apache::DBI is loaded before any module that issues a DB connect.
you can even load Apache::DBI from httpd.conf by
PerlRequire Apache::DBI
2. You can know if Apache::DBI is effective or not by installing Apache::Status
,load Apache::Status before Apache::DBI in that case and add a Location
section in the httpd.conf like:
--------------- httpd.conf---------------------
PerlModule Apache::Status
PerlModule Apache::DBI
<Location /perl-status>
SetHandler perl-script
PerlHandler Apache::Status
</Location>
------------------------------------------------------
point your browser to http://your_mod_perl_server/perl-status
and check the section about database conenctions.
i am not sure if this info answers your question but
i am describing something that works for me.
