I am setting up a new MySQL server that will be dedicated to only MySQL.
The new server runs CentOS 5. By default it only recognized 4GB so I updated the kernel to PAE version and now the OS recognizes the full 8GB of RAM.
I was talking with a server admin and he said that MySQL will only be able to use a max of 4GB and of that 4GB, 1GB will be used for the OS and the other 3GB will be used for the MySQL server.
First is it true that only the first 4GB will be used? If so, is there anything that I can do to make it use the full 8GB?
The processors do not support 64 bit, so I can’t go that route.
If MySQL will only use the first 4GB, then I can pull it and beef up some of our other servers that only have 2GB. I am just hoping that we can make use of all the ram as I feel that our DB server could really use it.
Thanks for you help with this.
