A manipulator has an operating unit including a trigger lever, a distal end working unit including an end effector and a yaw axis and a roll axis for changing the direction of the end effector, and a connector shaft interconnecting the operating unit and the distal end working unit. The operating unit includes an actuator block housing therein motors for actuating the yaw axis and the roll axis and a gripper operational quantity corrector for mechanically transmitting an operational action of the trigger lever to actuate the end effector. A controller calculates an interference amount caused on the end effector by the attitude angles of the yaw axis and the roll axis. The gripper operational quantity corrector is controlled by the controller to extend or retract a push rod, for correcting the operational quantity of the operational action of the trigger lever to compensate for the interference amount.

A distributed processing system delegates the allocation and control of computing work units to agent applications running on computing resources including multi-processor and multi-core systems. The distributed processing system includes at least one agent associated with at least one computing resource. The distributed processing system creates work units corresponding with execution phases of applications. Work units can be associated with concurrency data that specifies how applications are executed on multiple processors and / or processor cores. The agent collects information about its associated computing resources and requests work units from the server using this information and the concurrency data. An agent can monitor the performance of executing work units to better select subsequent work units. The distributed processing system may also be implemented within a single computing resource to improve processor core utilization of applications. Additional computing resources can augment the single computing resource and execute pending work units at any time.

The invention relates to the control of servers which process client work requests in a computer system on the basis of resource consumption. Each server contains multiple server instances (also called "execution units") which execute different client work requests in parallel. A workload manager determines the total number of server containers and server instances in order to achieve the goals of the work requests. The number of server instances started in each server container depends on the resource consumption of the server instances in each container and on the resource constraints, service goals and service goal achievements of the work units to be executed. At predetermined intervals during the execution of the work units the server instances are sampled to check whether they are active or inactive. Dependent on the number of active server instances the number of server address spaces and server instances is repeatedly adjusted to achieve an improved utilization of the available virtual storage and an optimization of the system performance in the execution of the application programs.

A method of delivering messages between application programs is provided which ensures that no messages are lost and none are delivered more than once. The method uses asynchronous message queuing. One or more queue manager programs (100) is located at each computer of a network for controlling the transmission of messages to and from that computer. Messages to be transmitted to a different queue manager are put onto special transmission queues (120). Transmission to an adjacent queue manager comprises a sending process (130) on the local queue manager (100) getting messages from a transmission queue and sending them as a batch of messages within a syncpoint-manager-controlled unit of work. A receiving process (150) on the receiving queue manager receives the messages and puts them within a second syncpoint-manager-controlled unit of work to queues (180) that are under the control of the receiving queue manager. Commitment of the batch is coordinated by the sender transmitting a request for commitment and for confirmation of commitment with the last message of the batch, commit at the sender then being triggered by the confirmation that is sent by the receiver in response to the request.The invention avoids the additional message flow that is a feature of two-phase commit procedures, avoiding the need for resource managers to synchronise with each other. It further reduces the commit flows by permitting batching of a number of messages.

The present invention discloses a solution that automatically decomposes a batch process into multiple units of work without changing code of a preexisting batch application. In the solution, the batch application is first analyzed to identify a set of processing segments or units of work, where each unit of work is of a size that minimizes interference with other data accesses. Once each unit of work is defined, these units can execute one at a time. A syncpoint can be established for each unit before it is executed, which locks the records included in the unit. After the unit of work executes, the record lock can be released and a new syncpoint can be established for the next unit. If an execution problem occurs, execution for the unit of work can be terminated and chances can be restored to the syncpoint.
