摘要： Provided is a method of managing a network system including a computer device which processes data, a storage system which is used in the computer device to store data, and a switch which connects the computer device and the storage system to each other. The storage system sets VLANs and the priority of each of the VLANs on the switch, VLANs including at least one of a control VLAN transferring mainly control data, and at least one of a user VLAN transferring data other than the control data. The switch transfers data in a manner that allows the VLANs of higher priority to precede the VLANs of lower priority. Therefore the storage system manages a network in accordance with the level of load or the like of respective VLANs.

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： An enqueue structure type is provided within a coupling facility to record the use state and to manage a request queue of resources shared among programs on computers of a system. All programs to use a shared resource issue a request to reserve the shared resource to the coupling facility before using it. The coupling facility affords the permission to use the resource to the programs if it is usable, and adds the programs to the resource request queue if unusable. When a program using the shared resource frees it, the coupling facility fetches a program from the beginning of the request queue, reserves the shared resource for the next program and notifies the next program that the use of the shared resource has been approved. On receiving the notification, the program uses the shared resource without asking the coupling facility for the approval of the use of the shared resource again. Further, exclusive control of shared resources by use of a spin lock having shared and exclusive attributes is implemented by using two locks for one shared resource, wherein the first lock is reserved and then freed after the second lock is reserved.
摘要翻译：在耦合设备内提供了一个入库结构类型，用于记录使用状态，并管理系统计算机上程序之间共享资源的请求队列。使用共享资源的所有程序在使用共享资源之前发出请求以将共享资源保留到耦合设备。如果可用，耦合设施提供使用资源给程序的权限，如果不可用，则将该程序添加到资源请求队列中。当使用共享资源的程序释放它时，耦合设备从请求队列的开始处获取一个程序，为下一个程序保留共享资源，并通知下一个程序，即共享资源的使用已被批准。在收到通知后，该程序使用共享资源，而不要求耦合设备再次批准使用共享资源。此外，通过使用具有共享和独占属性的自旋锁对共享资源的独占控制通过对一个共享资源使用两个锁来实现，其中第一个锁被保留，然后在第二个锁被保留之后被释放。

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.

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.
