> database programming
I have a web resource served by Apache with a Perl interface
to a MySQL database. In order to speed things up, I am using
mod_perl/Apache::DBI to create a persistent database connection
in a script that is run when Apache is started.
I want to make sure that I actually have a persistent connection.
The scripts that query the db were not originally written
with mod_perl in mind and each one contains a db connection
statement. The mod_perl guide says these will be ignored
if a persistent connection exists.
The obvious way to test would be to remove these statements
and see if the queries fail but I'm sure there must be a
more elegant and explicit test.
Does anyone know how to do this? Is there a connection id or
environment variable that I can get?
- MySQL 3.22.21
- Apache 1.3.9
- Perl 5.004_04
- Apache::DBI 0.87
- DBI 1.14
Thanks in advance...

Turn on Apache::DBI debugging. From the docs:
To enable debugging the variable $Apache::AuthDBI::DEBUG
must be set. This can either be done in startup.pl or in
the user script. Setting the variable to 1, just reports
about a new connect. Setting the variable to 2 enables
full debug output.
