I found out that my MySQL server is configured with only 128MB for innodb_buffer_pool_size.  That is not enough considering that I have a 8GB RAM server. It hosts MySQL server and an Apache/Catalina server.  What should I change this seeting to?


Question: What's the best way to pause my work in Virtualbox with Ubuntu as a guest?
Answer: Did you install Vbox additions correctly on the guest OS?

I don't see a problem with of the options here. If you can make Ubuntu hibernate it would be great but a suspend + pause option will work the same.

Hibernation can be simply described as: all content in memory save in disk file which is read again on boot up. (Memory>temp file in disk>power off:::power on>read temp file to memory> restore session>read new times, dates of other hardware info that might have changed in the meanwhile>ready)

Suspend can be simply described as: all content of memory will not be touched, most of your hardware will be powered down, once you start up again the memory session will be restored. (memory stays the same, static>most hardware powers off, memory is not turned off:::power back on>restore session>read new times, dates of other hardware info that might have changed in the meanwhile>ready)

So, in the end, its the same if you hibernate or suspend + pause you guest OS. The results should be the same.

Work on the hibernation part in my opinion, saves an extra "pause" click.
