摘要： Consistency of a shared disk is secured in system switching in a hot standby system. In the standby system in which an active computer and standby computer share the shared disk, when a write I/O request is issued from the active computer, information about a start of the I/O is recorded in, for example, a memory. When the I/O is completed, the information is deleted from the memory. When a failure occurs in the active computer, the active computer transmits the record of the information about the start of the I/O, to the standby computer. The standby computer verifies the record to recover a disk in which the I/O is to be executed.

摘要： A server system has servers that can be operated through switching as a primary system and a standby system, and a shared disk unit for storing data accessed by the servers. Each of the servers has a driver that acquires information on a configuration inside the shared disk unit after starting of the system. The driver sets the shared disk unit in an active state in which an access request can be sent to the shared disk unit. Access control determines whether the access request issued by an application should be sent on the basis of a management table indicating inhibited types of access requests for each access destination. The access control sends the access request to the driver when the access request is not inhibited for an access destination of the access request. By this arrangement, hot standby switching processing can be performed at high speed.

摘要： A cluster system includes a transmission side server cluster consisting of a plurality of computers, one of which is selected as a transmitting computer and at least another one of which is selected as a standby computer. When the transmitting computer transmits a message it received to a receiving side server, it also transmits the message to the standby computer that was selected, based on load information for all computers other than the transmitting one in the transmission side server cluster.

摘要： A computer system includes servers that receive messages sent from respective terminals, perform handlings associated with the received messages, and reallocate resources along with a variation in load deriving from the reception of the messages. The computer system comprises: an input counting unit that classifies the messages received from the respective terminals on the basis of an input classification table, and transmits messages, which are classified into each category, as time-sequential input information; and a resource control unit that predicts a minimum usage of each resource on the basis of the time-sequential input information, time-sequential load information representing a change in load on each resource, and load prediction rules in which a predicted value of a variation in load occurring in a server in a predetermined time due to the reception of messages is recorded.

摘要： A method of controlling cache allocation to be executed by a server computer is arranged to realize resource management for securing a proper cache size. The server computer is arranged to have a memory unit and a CPU. The memory unit stores a memory allowable size of a memory to be secured as a disk cache by each of the programs to be executed by the server computer. In a case that a new disk cache is allocated to the memory unit when accessing a disk drive under the control of the program being executed, the CPU reads from the memory the memory allowable size corresponding with the program and allocates the disk cache to the memory unit so that the disk cache may stay in the range of the memory allowable size.

摘要： A data transfer method for a computer system in which a computer is logically divided into a plurality of logical processing units and a logical coupling unit. A correspondence between a start of physical addresses of a memory of each logical processing units in a memory of the computer is stored in advance. If a first logical processing unit issues a write command to the logical coupling unit by designating a logical address of data, the logical coupling unit stores an identifier and the logical address of the first logical processing unit. If a second logical processing unit issues a read command of the data, a physical address of data storage corresponding to the logical address of the first logical processing unit is calculated in accordance with the identifier and the logical address of the first logical processing unit and the address correspondence. The data is read by using the calculated physical address.
