Abstract:
1. A method for getting dump of a computer system that adopts virtual storage management by which virtual storage is available using a main storage, an auxiliary storage, and an address translation table for indicating a location in the main storage or in the auxiliary storage to which an individual virtual-storage area is allocated, said method comprising: providing said auxiliary storage with a first auxiliary storage and a second auxiliary storage; operating the computer system using either of the first auxiliary storage or the second auxiliary storage; transferring content of the virtual-storage area on the main storage from the main storage to the auxiliary storage when a utilization ratio of the main storage becomes high; determining a location to which the address translation table is allocated, when occurrence of a failure in the computer system is detected; determining a location in the main storage, or in the auxiliary storage, where information in the virtual-storage area is stored, which is described in the address translation table; transferring the content of the virtual-storage area from the main storage to the auxiliary storage to which the content of the virtual-storage area is allocated when the utilization ratio of the main storage becomes high, if the content of the virtual-storage area is allocated to the main storage; switching the first auxiliary storage to the second auxiliary storage for use if the first auxiliary storage is used for operation, or switching the second auxiliary storage to the first auxiliary storage for use if the second auxiliary storage is used for operation, wherein when occurrence of a failure in the computer system is detected, content of an area in the main storage, which has not been associated with the virtual storage by the address translation table, is stored in a given area in the auxiliary storage.
