Hey James,
I was running into a similar situation but for a backend system that
ran multiple quick scripts to check state for automation. I was
working on building a daemon that would hold the connections, adding
as needed and destroying excess using some POE modules.
while working on it though, our DBAs upgraded us to Oracle 11 which
has a built in DB Pool (DRCP) which we are utilizing now. if you are
using an Oracle DB, look into it. here is the connection string I am
using:
$self->{dbh} = DBI->connect("dbi:Oracle:$config->{sid}",
$config->{user}, $config->{pass},
{ AutoCommit => 0, ora_drcp => 1,
ora_drcp_class => "feedAutomation" } );
