Abstract: PROBLEM TO BE SOLVED: To provide a data processor which performs the operation load management regarding a group of servers of asynchronous client/server computing system. SOLUTION: This data processor has a means which receives 21 an operation request from a client application, a means which is a means for selecting 23 a specific server in a group used to comply with the received operation request according to investigated available data and uses the investigated availability always in the current state when receiving the operation request irrelevantly to whether or not available data regarding the respective servers in the group are received so as to select a server from the group, and a means which puts the received operation request in a transmission queue for transmission to the specific server in the group.

Abstract: Provided are a computer program, method and system providing simplified administration of groups of computer programs. Command target qualifiers are defined which enable a command to be targeted at either an individual computer program or all members of a group of computer programs. Additionally, scope parameters are defined which enable a command to be targeted at specific computer system resources managed by the computer programs within the group. The computer system resources which are to be accessible to all members of a group have an associated scope parameter defining shared or group access and are held in shared storage, whereas computer system resources to be accessed by only one computer program in the group have a corresponding scope parameter and are held in the local storage of the individual computer program. The invention enables a reduction of the time taken to perform administration and control operations for the group and reduces the risk of inconsistent specification of commands that can arise when a system administrator is required to repeat entry of a command several times.

Abstract: Messages from a client application 111 are placed in a queue 112b for subsequent transmission to a selected one of a number of servers 121-123. The server to which each message is to be sent is determined when the message is placed into the queue, based on the server availability data known at that time and without waiting for availability data for each and every server. This eliminates an unnecessary source of delay. If the server availability data is updated before the message is transmitted, the server selection may be altered.
