Abstract
A method and system for dumping computer memory includes receiving an instruction to perform a dump of memory in a partitioned computer system where each partition has at least one processor and associated memory. The associated memory having a first portion and a second portion where the first portion is normally actively used for user application program or data storage. After receipt of the dump request, the source memory content is protected against corruption or contention from other program sources and copied into the second portion of memory. Preferably, the first and second portions are co-located RAM to provide speedy transfers of information. Access to the first portion of memory is then permitted by removing the protections and the user may have full access to run applications. The dump image is then transferred to any location as a background I/O task as the user executes his applications.
