Re: [PHP-DB] Optimize Tables
Thanx for this enlightening insight about cron jobs...
just a question.. when i run Optimize.php, i realise that you will echo some
statements. where will these statements be shown? since you put " >
/dev/null " instead of " > /dev/null 2>&1 ", does it mean that your echo
statements will be reflected in an email to me?
thanx.. i'm totally new to cron jobs, but thanx to sebastian's link on
crontab, i'm a little bit more knowledgable now! haha.. would appreciate
more insights! thanx!

Re: [PHP-DB] Optimize Tables
sorry, what do you mean by _cron_ job? I'm hoping to optimise my tables, for example on, every Monday 9.30am. by the way, is there a problem if I optimise my tables too frequently? i mean, i was told not to defragment or format my harddisk too often cos it will cause wear and tear to the hardware.. does this apply to optimisation of tables? will this be bad for my server then? thank you so much. - Original Message - From: "Dynamix" <[EMAIL PROTECTED]> To: "Ng Hwee Hwee" <[EMAIL PROTECTED]>; "DBList" <[EMAIL PROTECTED]> Sent: Monday, May 03, 2004 4:29 PM Subject: Re: [PHP-DB] Optimize Tables > yep, check http://www.phpclasses.org/browse/package/1527.html > > And you can run this using a cron job, so it just fit with your needs. > > Regards, > Hatem > > - Original Message - > From: "Ng Hwee Hwee" <[EMAIL PROTECTED]> > To: "DBList" <[EMAIL PROTECTED]> > Sent: Monday, May 03, 2004 11:19 AM > Subject: [PHP-DB] Optimize Tables > > > Hi, > > Is there a way to create a schedule to optimise my MySQL tables > automatically?

RE: [PHP-DB] Optimize Tables
Use a cron job Like: 0 0 * * * php Optimize.php > /dev/null This is an example for optimizing every table in all databases on your mysql server.

yep, check http://www.phpclasses.org/browse/package/1527.html And you can run this using a cron job, so it just fit with your needs.
