The Relational DAS requires that the SDO extension be installed.
The SDO extension requires a version of PHP 5.1, and the
Relational DAS requires a recent version that contains
an important fix for PDO. The Relational DAS requires a
version of PHP 5.1 later than 20050711.
an important fix for PDO. The most up-to-date information about
required levels of PHP should be found in the changelog for the
package on PECL. At the time of writing, though, the Relational
DAS requires the most recent beta level of PHP 5.1, that is
PHP 5.1.0b3.
</para>
<para>
The Relational DAS uses PDO to access the relational database,
and so should run with a variety of different relational databases,
but at the time of writing has only been tested with MySQL 4.1.
On Windows it operates correctly with the php_pdo_mysql driver
that comes with the pre-built binaries in PHP 5.1.0b3.
On Linux it is necessary to have the most up-to-date PDO
driver for MySQL. It may be necessary to uninstall the usual
driver that would have come from PECL (using
<command>pear uninstall pdo_mysql</command>
) and to enable pdo_mysql when configuring PHP, in order to pick up
the recent version built in to PHP.
</para>
<para>
The Relational DAS applies changes to the database within
a user-delimited transaction: that is, it issues a call to PDO's
<function>beginTransaction</function>
before beginning to apply changes, and
<function>commit</function>
or
<function>rollback</function>
on completion.
Whichever database is chosen, the database and the PDO driver
for the database must support these calls.
