Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

32 or 64 bit filesystems/files/OS's/CPU's

Determining if an OS is using 32 or 64 bits
This may be our number one question. Sadly I have not been able to find a definitive answer for Linux. If you have a Linux solution, please post it in our Linux forum. I will edit this post to include it.

32 / 64 bit (Solaris)
hp-ux (HP-UX Smilie)
command to check the bit (Solaris)
32-bit or 64-bit (Solaris, HP-UX, AIX)
64 or 32 bit kernel? (AIX)

C Programming Issues
Accessing large files from a 32 bit kernel on Solaris: Max file size can't exceed 2 GB
Accessing large file in LP64 mode on HP-UX: Unix file size - HP-UX and C++ Problem, managing >2Gb file
LP64 mode in general with a HP-UX example: Unsigned int

File System Size
Having a 64 bit kernel and a program compiled in 64 bit mode may not be enough. A particular file system may be be able to support large files. See: Unix file size - HP-UX

Here are some other threads and some web pages that might help...
