This assumes that 1.5G is used for the JVM, and then the remaining 500M of available memory. This 500M part of the memory must be used to load the system DLL, then the real left is perhaps only 400M, and now the key point arises: When you use Java to create a thread, in the JVM's memory will also create a thread object, But it also create

Create a physical volume with the command pvcreatCreate an entire disk as a physical volume, PVCREAT/DEV/SDATo create a partition as a physical volume: pvcreat/dev/sda23.

the physical volume to be deleted is not being used by any logical volume, use the Pvdisplay command to view the physical volume information:If a physical volume is being used by a logical volume, you need to back up the data for that physical volume elsewhere and then delete it.

Introduced/ dev/shm/ is a device that uses the Tmpfs file system, which is actually a special file system. the default size in Redhat is half of physical memory, so that time is not mkfs formatted. TMPFS is a memory-based virtual file system on the Linux/unix system .TMPFS can use your memory or swap partition to store the file ( that is, its storage space in virtual memory , the VM consists of real memory and swap ). Thus, TMPFS primarily stores staged files. It has the following 2 advantage
