not just by virtue of there being two handlers - Apache::DBI doesn't care
which handler makes the connection, just what the connect string is...
that is, any call to
my $dbh = DBI->connect('dbi:Oracle:$DBASE', $DBUSER, $DBPASS,
{RaiseError => 1, AutoCommit => 1, PrintError => 1}) || die $DBI::errstr;
will result in the same connection (per child, of course)
as soon as you change anything (like RaiseError => 0 or $DBUSER) you get a
new connection...
If Authen and Authz each have different $dbh credentials, then yes, you
should get two connections...
once the processing is finished, each connection will sleep until one of two
things:
you hit the same apache child again
the database cleans them up becuase they have been idle for too long
that's the benefit/drawback of Apache::DBI

I don't think keep-alive has anything to do with it...
I suggest you set $Apache::DBI::DEBUG = 2 in your startup.pl and watch the
debug information under httpd -X
