Swap and dump devices benefit from the underlying ZFS I/O pipeline architecture. You don't have to partition a disk to include swap and dump areas. The advantages to this model are as follows: In a ZFS root environment, swap and dump are configured as separate ZFS For more information, see Chapter 17, Managing System Crash Information (Tasks), in Oracle Solaris Administration: Common Tasks. You can change a system's dump volume by using When a system is installed, a ZFS swap volume and dump This variable has no effect on other programs' use of the /tmp directory.Ī dump device is usually disk space that is reserved to store system crashĭump information. Using your compiler's TMPDIR variable only controls whether the compiler is using the /tmp directory. Use your compiler's TMPDIR environment variable to point to another larger directory.

Mount the TMPFS file system with the size option ( -o size) to control how much swap resources TMPFS can use. Use the /tmp directory heavily and you do not monitor swap space usage,ĭo use the following if you want to use TMPFS, but your tmp directory, you are also using up swap space. This feature means that as you use up space in the The TMPFS file system allocates space in the /tmp directory from the system's This feature results in a major performanceĮnhancement for applications such as compilers and DBMS products that use /tmp heavily. Their associated information in memory (in the /tmp directory) rather than on disk, The TMPFS file system is activated automatically in the Oracle Solaris environment byĪn entry in the /etc/vfstab file. For example, SWAPFS might change the page's requirements for disk-backed swap storage. Because SWAPFS controls the allocation of memory pages, it has greater flexibility in deciding what happens to a page. The need for large amounts of physical swap space is reduced because virtual swap space does not necessarily correspond to physical (disk) storage.Ī pseudo file system called SWAPFS provides addresses for anonymous memory pages.

A system's virtual swap space is equal to the sum ofĪll its physical (disk-backed) swap space plus a portion of the currently available Memory pages and the physical storage (or disk-backed swap space) that actually back The Oracle Solaris OS uses the concept of virtual swap space, a layer between anonymous To as anonymous memory because no identity is assigned to the disk If the memory is backed by swap space it is referred Physical memory pages that contain the data for these mappingsĬan be backed by regular files in the file system, or by The virtual memory system maps physical copies of files on disk to
