I use a PHP or Perl codebase to access databases (mysql or postgres). I always
use a wrapper class to control the database connection because it makes the
code a lot more simple -- additionally I could easily insert logic in the
class to open a second connection to another database and duplicate all
inserts, updates and deletes. Alternatively the info could be queued in a log
file for delayed usage. However this is still far from a true HA setup. For
that either you need a lot of intelligent code or Oracle Parallel Server.
