The htop command is an various to top and supplies a extra user-friendly interface. Swap house additionally allows hibernation and safeguards critical processes by quickly offloading data. Nevertheless, it should solely be a complement to RAM as a outcome of a system that depends on swap would endure vital performance degradation. Assuming /dev/VolGroup00/LogVol02 is the swap quantity you need to add.
Swap Area Vs Digital Reminiscence
To make certain the swap file is routinely used after a reboot, add it to the /etc/fstab configuration file.

- In the fstab file, add the below entry to vi editors to edit the fstab file.

Also, take a look at the last part, “Kernel cache strain and swappiness,” of my different weblog submit for recommendations on tuning Linux swap area usage by the Kernel. Some recommend no swap or a swap dimension slightly bigger than the whole RAM. If you possibly can provide you with legitimate causes for this, then that may be your alternative. Nevertheless, this is hardly the case on servers, and you need to as an alternative steadiness your decision with the consequences swap will have on your specific applications.
