Rajesh,
Thanks for the suggestion. I tried what you told me. In my startup script I
did
use Apache2::Status;
use Apache::DBI;
before any modules that use DB connect were loaded.
I also included the handler for perl-status in the conf file as you
mentioned.
However as I access different pages the database connection doesn't persist.
I check netstat on the db server and I see connections from the web server
that appear and disappear.
I checked http://my_mod_perl_server/perl-status and it has a link that says
DBI connections but with no data in it.
Also I wasn't clear on why you are not using connect_on_init.
Thanks
Salem

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.
