<p>A method for creating an operating system dump comprises dividing a main memory of a computer system into at least three contiguous memory areas 102, comprising a primary memory area, a secondary memory area and a data memory area. Also comprises booting a first instance of an OS (operating system) into the main memory 104, loading a second instance of the OS into the secondary memory 106 area using the active first instance of the OS, stopping execution of the first active instance of the OS 108 if a critical execution error occurs and re-starting the computer using the loaded, second instance of the OS 110 which becomes the active instance of the OS. Method further comprises creating a dump of the primary memory area 112, and loading a third instance of the OS into the primary memory area 114. Thus the secondary instance continues regular operation of the primary instance, while dumping the crashed primary instance so it may be possible to minimize downtime after a crash.</p> |
