swap partition is useful: Swap is when the physical memory is not enough to put the data into the swap, so swap plays a role in the virtual memory, in a sense, it is also an increase in memory space. The general swap partition is set when the system is installed, if you forg

The swap space on Solaris is similar to the virtual memory on windows. It is used to temporarily cache the data in the memory on the hard disk and load the data into the memory as needed.The swap space is set when the system is installed. It is specially divided into a partition (equivalent to a partition) in the disk for the swap zone. however, in actual use,

Using the dd command to temporarily add swap partitions sometimes causes insufficient memory. you can use the method provided in this article to temporarily add swap partitions.

In Linux, this virtual memory is called SWaP. When installing the operating system, the installation wizard prompts you how much SWaP space you need to create. When we install Oracle 10 Gb in Linux, we find that the SWaP partition is too small, and we need to manually expand the size of the SWaP partition. Here, we wil
