1. RVM -- recoverable virtual memory

   Michael Graff <explorer@flame.org> — 1998-03-13T04:30:50Z

   Has anyone peeked that this to see if it can help make postgresql more
   stable in the face of a system crash or power loss?

   "RVM provides an unstructured recoverable virtual memory.
   The recoverable storage is represented by Unix files
   or disk partitions that applications can map at page granularity
   into the address space of a process. Simple, non-nested atomic
   transactions guarantee permanence of changes to recoverable storage
   across system crashes. Applications can schedule transaction logging
   actions to enhance performance. The design stresses simplicity, ease of use,
   and high performance. Unix compatibility is standard, while optional
   Mach-specific extensions are supported for additional flexibility
   and performance. RVM has been extensively used in the clients and
   servers of the Coda File System, and in the Venari system."
