NAME

ResourcePool::Resource::DBI - A ResourcePool wrapper for DBI

SYNOPSIS

use ResourcePool::Resource::DBI;

my $resource =  ResourcePool::Resource::DBI->new(
                       $data_source, 
                       $username, 
                       $auth, 
                       \%attr);

DESCRIPTION

This class is used by the ResourcePool internally to create DBI connections. Its called by the corresponding ResourcePool::Factory::DBI object which passes the parameters needed to establish the DBI connection.

The only thing which has to been known by an application developer about this class is the implementation of the precheck() and postcheck() methods:

precheck()

Performs a $dbh->ping().

Returns true on success and false on fail.

postcheck()

Always returns true, but does a rollback() on the session (if AutoCommit is off).
