Method and system for identifying history of console devices capable of rapidly analyzing and determining a factor of obstacle of a computer system due to misoperation of a console device in the computer system comprising at least one central processing unit including a computer, a main console device connected thereto and a plurality of sub-console devices for controlling the operation of the computer. History of the console devices as to which one of the sub-console devices command data has been issued from and/or which one of the sub-console devices command data has been sent to is examined to analyze and determine the factor of computer system obstacle.

Method and apparatus for monitoring communication between a computer and

An automatic operation control system for controlling the automatic operation of a computer system, stores in a storage unit the status informations of hardware configuration and software configuration of a computer system, a running event of the operating system and application programs, and an operation event of the computer system, and supplies a procedure for an operation command to be executed in accordance with the configuration information and the occurred event.

Operation control technique for computer system by driving a command

A control apparatus for realizing remote operation control for a computer system is interposed between the Computer system and a master console for supervising data stream on a data transmission/reception signal line existing between the computer system and the master console. Occurrence of error in the computer system is messaged to a remote terminal through a public telecommunication line. Commands for the computer system can be inputted from the remote terminals.

Remote operation control for computer system

Fault monitoring/controlling apparatus and method for a data processing system comprises one or more computer systems, monitor and control apparatuses connected thereto for monitoring and controlling the associated computer systems and a single supervision/control system provided at a site remote from the computer systems. When abnormality taking place in the computer system is decided as a fault, report of the fault occurrence is automatically effectuated to the remotely located supervision/control system, which responds to the reception of the fault report and issues, if necessary, a command requesting additional supply of detailed fault information to the computer system suffering the fault. The additional fault information is comparatively collated with the fault information accumulated (precedents). When a reference precedent which coincides with the fault occurring currently is found to be present as the result of collation, a recovery procedure is generated on the basis of the precedent data to be subsequently transmitted to the computer system of concern. A plurality of computer systems can be monitored in a consolidated manner, wherein fault taking place in the computer systems can be removed rapidly through diagnosis and execution of appropriate procedure.

Monitoring and controlling system and method for data processing system

In a computer network system in which a plurality of computer systems managed by different managers are connected, each computer system in the network system is provided with a group of tables for storing the characteristics of computer systems in the network system with which the site of that computer system is communicatable, the cumulative total of account information when that computer system requested the execution of jobs to another site, the cumulative total of account information when the site of that computer system executed jobs requested from another site, and the calculated value of the balance of accounts between the site of that computer system and each site in correspondence to each of sites in the network system and is also provided with a group of processing programs. When the site of that computer system requests the execution of a job to one of the other sites, the site of that computer system examines the calculated value of the balance of accounts between the site of that computer system and each of the other sites so that a site to which the execution of the job is to be requested is selected on the basis of the balance of accounts between the site of that computer system and the other site.

Control method and apparatus for computer network system

A distributed interactive processing in a complex computer system including a plurality of work stations (IWS's), each having predetermined server processes, at least a host computer (HOST), communication lines interconnecting between the plurality of IWS's and the HOSTs, and communication control portions to establish and to control communication paths between processes to conduct a process-to-process communication between the IWS's and the HOSTs. Each IWS has therein a process to implement an assigned processing request and a request control section to analyze the processing request issued by the own IWS and to determine a server process required to implement the processing request. Among a result of the request analysis, a predetermined server process is executed in the own IWS. The communication control portions establish a communication path between an associated server process in the relevant HOST and the request process in the IWS in accordance with the determination in the IWS regarding server process and thereby enable the IWS to perform an on-line interactive processing in combination of the server process in the HOST and the process in the IWS.
