PURPOSE:To record the action of resources in correspondence to a processor, by providing a means to record the action of resources, a means to stop recording at the specific time and a display means to a system in which plural processors share a single resources. CONSTITUTION:The rack that four processors that work independently have given an access request to a main storage of shared resources is sent to a storage device address controlling part 01 via signal lines 101-104. At the part 01, the working state of the main storage is sent to a storage device 10 via a signal line 03 so that this working state is recorded independently to the device 10 via a signal line 03 so that this working state is recorded independently to the device 10 with each processor. The address and the data which are given to the main storage from the processor are supplied to the device 10 to be recorded to the address designated with each processor. When an error is caused at the main storage, the part 01 stops recording to the device 10. Then the data that is recorded to the device 10 before the error arises is displayed on a display device 43 via a signal line 120. At the same time, the signal given from a display changeover switch 05 is sent to the part 01 via a signal line 02 to switch the contents displayed on the device 43. |
