摘要： A high-speed cache is shared by a plurality of independently-operating data systems in a multi-system data sharing complex. Each data system has access both to the high-speed cache and the lower-speed, secondary storage for obtaining and storing data. Management logic and the high-speed cache assures that a block of data obtained form the cache for entry into the secondary storage will be consistent with the version of the block of data in the shared cache with non-blocking serialization allowing access to a changed version in the cache while castout is being performed. Castout classes are provided to facilitate efficient movement from the shared cache to DASD.

摘要： A method for controlling coherence of data elements sharable among a plurality of independently-operating CPCs (central processing complexes) in a multi-system complex (called a parallel sysplex) which contains sysplex DASDds (direct access storage devices) and a high-speed SES (shared electronic storage) facility. Sysplex shared data elements are stored in the sysplex DASD under a unique sysplex data element name, which is used for sysplex coherence control. Any CPC may copy any sysplex data element into a local cache buffers (LCB) in the CPC's main storage, where it has an associated sysplex validity bit. The copying CPC executes a sysplex coherence registration command which requests a SES processor to verify that the data element name already exists in the SES cache, and to store the name of the data element in a SES cache entry if found in the SES cache. Importantly, the registration command communicates to SES the CPC location of the validity bit for the LCB containing that data element copy. Each time another copy of the data element is stored in any CPC LCB, a registration command is executed to store the location of that copy's CPC validity bit into a local cache register (LCR) associated with its data element name. In this manner, each LCR accumulates all CPC locations for all LCB validity bits for all valid copies of the associated data element in the sysplex -- for maintaining data coherency throughout the sysplex.

摘要： A Structured External Storage (SES) device/processor is connected to two or more DP systems, thereby loosely coupling the systems. The SES is capable of holding data objects of two distinct types (List objects and Cache objects), and communicates commands and command responses with the systems using a message protocol. A support facility within a processor on which a system is executing receives status indications from the SES without interrupting mainline system execution. Within the SES, a serialization mechanism allows more than one command to execute in parallel without loss of data object integrity, or command consistency. A forward completion mechanism sends to systems early notification of completion of certain commands, without permitting results inconsistent with this notification to be obtained by the systems. And a restart mechanism permits interrupted commands to be restarted by the initiating system or, in certain cases, by another system.

摘要： Apparatus and method insuring that data objects used to maintain state information for shared data at a local central processing complex (CPC) are 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.

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： One or more central processing complexes (CPC's), each with one or more programs being executed, issue commands to a structured electronic storage (SES). The commands include ones that create or delete data structures in SES, and attach or detach users to the data structures. The commands include a comparative authority value operand and a new authority value operand. A data structure or user control information has an associated existing authority value. If the comparative authority value matches the existing authority value, the existing authority value is replaced by the new authority value, and the command is executed. If there is a mismatch, the existing authority value is returned to the program that issued the command, and the command is not executed in SES. This enables software to serialize management of SES and maintain a consistent view of objects in SES in the presence of faulty CPC's, without causing correctly operating CPC's to experience errors or undue delays.

摘要： One or more Central Processing Complexes (CPC), each with one or more programs being executed, become command initiators by issuing commands requesting an action to be performed by a command responder. The responder is a Structured Electronic Storage (SES) which comprises a coupling facility. The SES receives commands to be executed over a plurality of links interconnecting the CPC's and SES, and returns a response to the program that issued the command. The SES is the focal point for the CPC's to share data, control locks, and manipulate lists or queues. This couples the autonomous CPC's into a System Complex (Sysplex) displaying a single system image. An indicator associated with each of the links is set by SES when it appears to a initiator that problems on the link exist. The set state of any indicator prevents SES from starting execution of any subsequent commands. This preserves the orderly, sequential execution of commands to insure consistent states of data in SES, and allows the program that issued the command to determine exactly how the command ended at SES. Data associated with execution of the command is stored in a status save area of SES for subsequent access by the program.

摘要： A message path mechanism in a network having central processing complexes (CPCs) joined by message paths to a coupling facility. The coupling facility locates message paths for sending messages from one CPC to another and for sending messages between the coupling facility and one or more of the CPCs. A message path status table is provided having an entry for each of the message paths. Each entry has an indicator indicating whether its message path is active or inactive. multiple connections between the coupling facility and systems in the CPCs are registered in the coupling facility. Also provided is a mechanism for validating that each message path is connected properly such that if a message path is disconnected and then reconnected to a CPC, the validation mechanism insures that the message path has been reconnected correctly.
