Subject:Re: move to 64 bit
View as plain text  
Hi! Essentially this is true. However let me qualify that a little...  
Clearly to take advantage of 64 to you'll want to change your memory  
settings and allocate something in my.cnf over 2G. Also you'll want  
to be using OS X 10.4.n, 10.3 and earlier don't really support 64  
bit. Now that the truly basics are done...

Beware, we encountered a problem with OS X 10.4.n, any 64 Bit MySQL  
and InnoDB... Under the right mix of conditions when you allocate  
Innodb more than 2Gbytes of memory it is possible at some point to  
hang the machine, and it will restart 5 minutes later when the system  
watchdog processes cycle the power supply to fix itself. Turns out  
its an OS bug, and it's the sort of thing where you need the Sun,  
Moon and 18 planets to align together to happen, which made it a  
little difficult to track down at Apples end. The good news is I'm  
told they found it and nuked it, and we will likely see the fix  
included in OS X 10.4.5... just wanted to warn you in case you are  
using InnoDB and you start to see the Sun line up with the Moon and...

Other than that, go for it, it all fits together beautifully,  
changing the binary is all you need to do.

Best Regards, Bruce
