If using new_or_cached() method, will ping() dbh on every fetch from |
39
|
|
|
|
|
|
|
cache to ensure that the dbh is connected. This extends |
40
|
|
|
|
|
|
|
the basic Rose::DB::Cache behaviour beyond mod_perl/Apache::DBI. |

Rose::DBx::AutoReconnect was written to allow new_or_cached() to |
53
|
|
|
|
|
|
|
work with MySQL's "morning bug" and to allow for restarting |
54
|
|
|
|
|
|
|
your database without restarting your application. |
