Hi Simon,<br>
<br>
Reducing the number of connections to the database from three to one
will reduce the responsiveness and will definitely hurt when trying to
debug issues (performance, etc). My recommendation is that each
application have at least one unique connection to the database.<br>

<p class="MsoNormal">This setup passes changes to the
Common::DB::Schema class on to the
Catalyst app model classes.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">All three of these apps run under a single
Apache 1.3.42/mod_perl
1.31 server.<span style=""> </span>It appears that each server
process creates a unique database connection variable for each of these
apps.
Although these database connections get reused from request to request,
I would
like to make things even more efficient by having a single database
connection
variable per server process which gets shared across all 3 Catalyst
apps. <span style=""> </span>How do I update my model to accomplish
this?</p>
