    Abstract: PROBLEM TO BE SOLVED: To provide a method and a device to intensify capacity restriction imposed by a software license agreement in an information processing system separated into a plurality logical partitions. SOLUTION: A job load management program to be executed by partitions measures actual consumption of processor resources by the logical partitions for prescribed average time intervals of addition and compares the measured actual consumption with the maximum allowable consumption. If the actual consumption exceeds the maximum allowable consumption, the job load management program calculates a capping pattern and caps the actual consumption of the processor resources by the partitions based on the calculated capping pattern by mutually acting with a logical partition management program. Pseudo weights are further allocated to the partitions. The logical partition management program judges whether or not an allowable shared level of the processor resource is exceeded by adding the pseudo weights to all partition weights.

    Abstract: Apparatus and method insuring that data objects used to maintain state information for shared data at a local central processing complex (CPC) is coherent with respect to state information maintained at a structured external storage facility (SES) over a link is valid. An error detector is attached to the CPC side of the link for detecting errors on the link, and, when an error is detected, setting a error state pending (ESP) latch to indicate that the link has failed and that the shared data in the local data object may be invalid because a message invalidating the data may not have been received by the CPC. In data processing operations, the ESP latch is interrogated by a central processor in the CPC to determine the health of the message path to the SES facility. A local cache vector reflecting the validity of the shared data in the local cache may then be interrogated to determine if the shared data in the local cache is valid. If a healthy path has continuously existed and the vector indicates that the local cache data is valid, the integrity of the data can be relied on.

    Abstract: A mechanism for communicating messages, each including a command and a response, in a network having central processing complexes (CPCs) and one or more coupling facilities. Each coupling facility has a central processor for executing instructions and a main storage. Messages are sent from a message control block in the main storage of the CPC sending the message, and the response to the message is received in a message response block of the CPC without an interrupt to the program being executed by the central processor of the CPC. Each message from a CPC to the coupling facility may include a command and an indicator bit which instructs the coupling facility to execute the command either in synchronism with or asynchronously to the execution of the sending processor. The coupling facility executes the command and returns a response which is received in a message response block of the main storage of the sending CPC without an interrupt to any program being executed by the central processor of that CPC.

    Abstract: The configuration of the logical processors of a logical partition is managed dynamically. A logical partition is initially configured with one or more logical processors. Thereafter, the configuration can be dynamically adjusted. This dynamic adjustment may be in response to workload of the logical partition.
