The present invention relates to a method and apparatus for dumping memory. More particularly a computer-implemented method of saving at least some data within volatile storage to non-volatile storage when a computer system panics is described. The method includes the steps of: the computer system defining a specified portion of volatile storage () containing data to be saved as a dump device (), rebooting () the computer system without affecting the data within the dump device, and the computer system copying () the data in the dump device to non-volatile storage (). A reboot of the computer system after copying the data to non-volatile storage is not necessary for the computer system to begin () normal operation.

Method and apparatus for dumping memory

In one configuration, a method for operating a computer includes booting an operating system having a plurality of tunable kernel subsystems; storing a representation of at least one base tunable having a set of inheritable properties in a memory of the computer; and storing, in a memory of the computer, a plurality of representations of instances of at least one of the stored base tunables, each instance including at least one inheritable property of the stored base tunable, wherein representations of at least a first instance and a second instance are stored at different memory addresses. The first instance and the second instance include a plurality of values, and differ in at least one corresponding value.
