  • Patent number: 8392759
    Abstract: A test method including executing a data transfer instruction with regard to transfer of data between a plurality of multiplexed storage devices and a plurality of main systems logically connected to the plurality of storage devices, storing an initial value of an operand upon execution of the data transfer instruction, re-setting the stored initial value to the operand upon occurrence of an interrupt triggered by an exception, and repeatedly executing the data transfer instruction and re-setting the stored initial value to the operand, by the main system accessing the storage device, until the data transfer instruction is completed normally.
    Type: Grant

  • Patent number: 7483817
    Abstract: A connection characteristics determination unit determines whether connection mechanisms provided in a data processing system have differences in connection characteristics in terms of hardware implementation or not. If there is no difference in the connection characteristics of the connection mechanisms, a first load test execution unit determines, for all processors, a load test combination program of a test program and a load program having a load effect, and allocates them to the processors so as to execute a load test. If there is a difference in the connection characteristics of the connection mechanisms, a second load test execution unit determines, for each of a plurality of processor groups sorted in accordance with the difference of the connection characteristics, a load test combination program of a test program and a load program having a load effect, and allocates them to a plurality of processors so as to execute a load test.
