Abstract: If a plurality of operating systems are running in one computer and each of those operating systems has its own managed time, which is different from others, then trace log information items collected by those operating systems and merged in order of their generated times may not be as they are generated actually. In order to avoid such a problem, therefore, the present invention provides an operating system management system with recording means for storing a check point trace in the operation trace information of each of those operating systems, thereby finding the correspondence among those check point traces by searching the operation trace information item of each operating system, then adding such additional information as a time difference, a counter value, etc. to the operation trace information.

Abstract: A computer system having a plurality of operating systems and a module for switching the operating systems in view of priorities of tasks to be performed by each of the operating systems. Each of the operating systems performing a plurality of processes or threads in accordance with the priorities assigned to these processes or threads has a module for notifying the computer system of the priority of the currently executing process or thread. The computer system includes a module for translating the priorities sent from each operating system into priorities (normalized priorities) common-throughout the computer system, and a module for comparing the normalized priorities obtained by the priority translation module in order to select and execute preferentially the operating system having a common priority higher than that of any other operating system.

Abstract: An operation site has copy management information including state information that is used when executing a remote copy. The copy management information is stored in a storage device included in each of all storage device subsystems in this computer system. The copy management information is updated every time a remote copy is executed. When the operation site fails, by use of a copy management program in another operatable site, and with reference to the copy management information stored in the storage device of the storage device subsystem in each site, the copy is executed from a point to which the copy processing has progressed before the failure. As a result, when the production site in which an application is operated suffers from a disaster, it is possible to quickly recover data at the time of the disaster by executing a disaster recovery management program from another site in which no failure occurs, and then by restarting the remote copy.

Abstract: In the present invention, when there is a change in a group of volumes managed by a host computer, data duplication processing is immediately carried out against the changed volume. The host computer 10 comprises a volume-managing portion(unit) 12, a data duplication-controlling portion(unit) 11 which executes the data duplication of the data stored in the volume 32 in the main data center 3, and a data duplication storing portion(unit) 13 which stores data necessary for the data duplication. The data duplication-controlling portion 11 compares data held by the volume-managing portion 12 and the data in the data duplication storing portion 13, and updates the data in the data duplication storing portion 13 based on the data held by the volume-managing portion 12.

Abstract: A computer system of a multi-operation-system (multi-OS) has a main memory having a memory area for a first OS and a memory area for a second OS, both the areas being independent from each other, and a plurality of I/O devices divisionally allocated to the first OS and the second OS. The first OS is loaded in the first OS memory area, and thereafter when the first OS is operated, the second OS is loaded in the second OS memory area and initialized. When the first OS is operated, the first OS hardware resources and the second OS hardware resources are registered by the first OS. Thereafter when the first OS is operated, the first OS inhibits the registration of an interrupt number already allocated to the second OS I/O device. In response to an interrupt request from a second OS I/O device, the second OS starts operating.

Abstract: A job network setup method in a job management system which controls execution of jobs according to a set job network and which allows setup for data transfer from a preceding job to a succeeding job comprises enabling specifying such that data can be transferred from the preceding job to the succeeding job by linking a standard output of the preceding job to a standard input of the succeeding job when setting the succeeding job in setup of the job network.

Abstract: A cache mode selection method and system sets to a cache load inhibit mode a cache mode used for a random access dataset of lower access hit ratio if use ratio of a data transmission path exceeds beyond an upper use ratio limit. It also sets to the cache load inhibit mode the cache mode used by parts of a sequential access dataset. These make it possible to select a proper cache mode depending on state of a load dynamically to prevent an I/O response from decreasing so that the hit ratio can be increased.

Abstract: A system and method for continuous operation of a virtual machine system having operation modes including a guest mode in which virtual machines are operated and a nonguest mode in which a virtual machine monitor for controlling the virtual machines is operated. The continuous guest is a virtual machine which does not stop executing operation at the occurrence of a failure due to program error of the virtual machine monitor. A main storage is provided with two areas. One of the two areas is a continuous guest area having the same host absolute address in the nonguest mode as a guest absolute address in the guest mode, the area is used by the continuous guest which is a virtual machine which continues to operate on transition of the operation mode from the guest mode to the nonguest mode. The other is an area in which a program module for dispatching the continuous guest in response to the transition of the operation mode from the guest mode to the nonguest mode.

Abstract: In a computer system having a central processing unit, a main storage and at least one I/O device, a plurality of operating systems (OS) can simultaneously run under the control of a control program. For executing an I/O instruction using a central processing unit, a plurality of resident areas of said main storage which do not overlap one another are assigned, under the control of the control program, to the plurality of OSs as main memories therefore, respectively. In responding to an I/O instruction issued by a running one of said plural OSs, an address of said main memory assigned to said running OS which participates in an I/Oo operation requested by said I/O instruction is determined without intervention of the control program, and the address is translated into an address of the main storage of the computer system without intervention of said control program. The I/O operation is then executed by using the address resulting from said address translation.

Abstract: An OS control method for controlling an operating system (OS) running in a computer system on which a plurality of OSs run and which includes an instruction processor, a control program for controlling running of a plurality of OSs, a main storage, an external storage device, and an address translation circuit. In the course of processing performed by the instruction processor, predetermined operation of the instruction processor is monitored to output trace data affixed with an address conforming to the running OS in accordance with predetermined conditions for the predetermined operation. Address for the running OS is translated into a real address on the main storage. A debugging assist unit outputs trace data to one of plural storing areas of the main storage corresponding to the running OS at the translated real address.

Abstract: A method and an apparatus for configuring multiple absolute address spaces are disclosed which simultaneously operate a plurality of virtual machines (VMs) respectively having operating systems on a single real computer by allocating a plurality of logical address spaces to an absolute address space. A different absolute address space is allocated to each of the VMs, whereby the respective VMs can access a main storage with a designated address without adding a constant to the designated address.
