Rico, Shouldn't you consider this as "what happens, while in production, should the script fails?", whether its DB related or not. In that case, how would you want to handle the error? Do you, or the system admin, want to be notified one way or another of the failure? Do want to implement a backup in case that failure happens as an 'automatic recovery' mechanism? As a system/network admin, I go by 3 guidelines: 1) Prevent failure as much as I can (either system hardware, software applications, hacks/exploits/vulnerabilities, etc.). 2) In the event that 1 fails, what's the recovery process? How fast can I recover from it? 3) If 2 fails, then there's something wrong with the whole process, which I need to expand my knowledge & skillset. In my past experiences, I haven't yet got to stage 2 because there precautions you can take to detect when a failure is about to happen so that stage 2 will never happens. What you need to consider is how important is this? Is it mission critical? Regards, Tommy -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
