Abstract
A method, computer system, and computer program product for operating a computer system to carry out a data dump of a data image of memory contents. Computer operations are temporarily suspended to service the dump request in order to dump the volatile memory contents required for the data image and to generate a record of the non-volatile memory pages which need to be dumped. Computer operations are then resumed under supervision of a monitoring process which screens access requests to the non-volatile memory against the dump record. A request relating to a page contained in the dump record is acted upon by writing the contents of that page to the dump storage space, so the page contents is dumped before it is modified. The dump record in continually updated to keep track of what is still outstanding to complete the dump until such time as the dump is complete.
