Configuration of swap on Oracle server

Configuration of swap on Oracle server

On Oracle servers, setting the appropriate swap size can improve Oracle's performance, and for Oracle 11g, the physical memory on the Oracle server and the swap size to be set are as follows:

If the physical memory is less than or equal to 2GB, then swap should be 1.5 times times the physical memory;

If the physical presence between 2GB to 16GB, then the swap size is best equal to physical memory;

If the physical memory is greater than 16GB, then the swap setting is sufficient for 16G.

We can use the operating system command free-m to see the physical memory, swap size, in megabytes
