SL::DB::Cache - database handle caching for kivitendo |
|

|
|
| 35 |
=head1 DESCRIPTION |
|
| 36 |
|
|
| 37 |
This class provides database cache handling for kivitendo running |
|
| 38 |
under FastCGI. It's based on Rose::DBx::Cache::Anywhere. |

Rose::DBx::Cache::Anywhere - get Apache::DBI behaviour without Apache |

|
|

=head1 DESCRIPTION |
|
| 12 |
|
|
| 13 |
This class is used by Rose::DBx::AutoReconnect. |
|
| 14 |
The author uses |
|
| 15 |
Rose::DB with Catalyst under both the Catalyst dev server and |
|
| 16 |
FastCGI and found that the standard Rose::DB::Cache behaviour |
|
| 17 |
did not work well with those environments. |

|
|
| 21 |
=head2 prepare_db( I<rose_db>, I<entry> ) |
|
| 22 |
|
|
| 23 |
Overrides default method to always ping() dbh if not running |
|
| 24 |
under mod_perl. |
