A multiplicity adjustment agent collects request information database from a sub-system including an element of a system to be monitored. An individual sub-system's multiplicity adjustment server sorts and merges request information collected from each sub-system for each element/request path. An integrated multiplicity analysis server calculates a necessary multiplicity on the basis of the request information.

Multiplicity adjustment system and method

In a transaction processing method for executing a series of a plurality of transactions in accordance with a workflow, compensation processing is registered as an error recovery flow when each transaction is executed, the compensation processing executing error recovery processing when an error occurs while the transaction is executed, and a series of compensation processing is executed in parallel in accordance with the registered error recovery flow when an error occurs while any of the transaction is executed.

Transaction processing method and apparatus

A software install management method, and an apparatus for the method, can prevent a greater number of softwares than a contracted license number from being installed in a server-client system. A serve comprises a software management portion for saving a software to be installed in a software storage portion, a table management portion for registering an information representing an install history of the software saved in the software storage portion and an information representing a license number to a history management table and to a license number management table, respectively, and a software transmission portion for transmitting the software to the client, and client comprises a software management portion for judging whether or not the software saved in the server is to be installed, a software reception portion for receiving the software transmitted from the server and storing it in a software storage portion, and a table management portion for registering an information representing the software saved in the software storage portion t a management table.

Method of and apparatus for managing licensed software

A client-server system is provided in which access to a service by a user can properly be controlled, even if an approval by another user is required for receiving the service. First, the server,executes a log-in processing by using a user identifier and password transmitted from the client terminal,, and a user control file,. Next, the server,executes a service control by using a service supply request transmitted from the client terminal,and a service control file,provided with the server. When the server determines that an approval by another user is required for providing the service, the server executes the approval request to the client terminal,that the concerned user uses. When the reply to the approval request is affirmative, the server executes the processing in accordance with the foregoing service supply request. When the reply is negative, the server informs to the user who made the foregoing service supply request that the approval is rejected.

Client-server system for controlling access rights to certain services by a user of a client terminal

A printing system having a plurality of printers and computers connected to each other through a communication network is disclosed. A first computer is connected with a second computer through the network. A first computer generates a printing job and a print request signal for executing the printing job according to a print request designated by the user to a first printer. A first computer also generates a continued print request signal containing information unique to the user according to a continued print request from the user requesting the execution of the printing job to a second printer. The printing job and each signal are transmitted to the communication network from the communication unit of the first computer. A second computer receives the printing job and each signal through the communication network. The second computer further causes the first printer to execute the printing job designated by the user in accordance with the print request signal. Upon receipt of a signal containing a continued print request and information unique to the user, the second computer decides that the information unique to a user belongs to the user designating the printing job. In the case where it is decided that the signal containing a continued print request and information unique to a user belongs to the user, the second computer causes the second printer to execute the printing job according to a continued print request.

Printing system

A remote print system in which a plurality of computers connected to a network are each allowed to finely control a printer (NPR) connected to the network and a computer used in the remote print system. A NPR control library serves as an interface to the NPR, a message is transferred to a NPR controlling daemon under the direction of an interprocess-communication mechanism (IPC), and the NPR controlling daemon performs a requested control operation of the NPR in accordance with the message by utilizing protocol for NPR control.

Remote print system having a plurality of computers which are capable of

In a printing system including a plurality of terminal equipment, a plurality of printers which can be shared by the terminal equipment, one or more printer/spooler control servers each for receiving a print from the terminal equipment and for controlling the print by the printer, and a distributed printing management server, for various errors which occur in the printers, the contents of the errors are informed to the user and an error recovery process according to the error is realized. Thus, a use efficiency, performance, reliability, and serviceability as a printing system are improved.
