摘要： A mechanism for automatic reallocation of shared external storage structures is provided. The shared external storage divides the dynamically allocable storage into fixed sized blocks referred to as allocation units. To create an object of a specific type, the shared external storage uses some number of allocation units. If the object will fit in one allocation unit, then it is placed in one allocation unit. If the object is larger than one allocation unit, then the appropriate number of allocation units is obtained and chained together to contain all of the information of the required object. When an object so allocated is no longer needed, the shared external storage breaks the object down to a set of one or more fixed sized allocation units. The shared external storage then returns the allocation units to the pool of available objects.

摘要： System-managed duplexing of coupling facility structures. A plurality of instances of coupling facility structures are maintained in a plurality of coupling facilities. Duplexing processing associated with the plurality of instances is managed by one or more operating systems, making many of the steps associated with duplexing transparent to the exploiters of the coupling facility structures. System-managed duplexing provides high availability for coupling facility structure data via a robust recovery mechanism (i.e., duplexing failover).

摘要： Storage is managed in a shared electronic store (SES) by assigning storage classes (STCs) to each directory entry having a data item stored in SES. The assignments of directory entries and data elements to the respective STCs can be changed at any time by any CPC. Eventually, no free space remains in the SES cache, and then space for new directory entries and data items must be obtained by reclaiming space occupied by directory entries and associated unchanged data items. The reclaiming of SES space is controlled on a STC basis. Any specified STC may reclaim from itself or from another STC using reclaiming software/microcode in SES, which includes a reclaim vector, a reclaim counter, a queue, and reclaiming controls. The vector and counter have respective elements for all possible STCs to controls how a specified STC may reclaim space from any or all target STC. Any enabled target STC reclaims its space according to an LRU algorithm maintained by a queue for the STC. A CPC can issue a command to load different values in target STC elements in the SES vector for a specified STC to control how reclaiming is apportioned for the specified STC. In SES, associated target counter elements are loaded from its vector. Reclaiming is done automatically in SES upon each directory miss in the current target STC having a non-zero counter value, when no free space exists. The counter is decremented for each reclaimed directory entry until its count reaches zero, and then the counter element for the next non-zero target STC is used for reclaiming until it reaches zero. When all STC elements in the counter are zero for the specified STC, the counter elements are reloaded from the vector elements to repeat the reclaiming operation, as long as a repeat factor for the specified STC has not reached zero. The repeat factor is decremented each time the counters are loaded from the vector. When the counters and repeat factor have all reached zero, reclaiming is disabled for the specified STC.

摘要： A mechanism is provided for multi-part aggregated variables in structured external storage. The shared external storage provides a serialized, aggregated structure update capability. The shared external storage identifies each local value for which a group value is needed by name. Each time a member writes out its value, the member specifies the name of the object, the member's current value, and the type of aggregate function to apply (e.g., minimum, maximum, etc.). The structured external storage in one atomic operation updates the member's value, recalculates the aggregate of all of the individual values, and returns the aggregate to the member. The advantage of this approach is that it requires only one write operation to the structured external storage. The update operation does not require locking, because the operation is atomic.

摘要： A method for managing a cache structure of a coupling facility includes receiving a conditional write command from a computing system and determining whether data associated with the conditional write command is part of a working set of data of the cache structure. If the data associated with the conditional write command is part of the working set of data of the cache structure the conditional write command is processed as an unconditional write command. If the data associated with the conditional write command is not part of the working set of data of the cache structure a conditional write failure notification is transmitted to the computing system.

摘要： A system, method and computer program product for calibrating a Time Of Day (TOD)-clock in a computing system node provided in a multi-node network. The network comprises an infrastructure of computing devices each having a physical clock providing a time base for executing operations that is stepped to a common oscillator. The system implements steps for obtaining samples of timing values of a computing device in the network, the values including a physical clock value maintained at that device and a TOD-offset value; computing an oscillator skew value from the samples; setting a fine steering rate value as equal to the opposite of the computed oscillator skew value; and, utilizing the fine steering rate value to adjust the physical clock value and correct for potential oscillator skew errors occurring in the oscillator crystal at the computing device.
