摘要： Validation of a re-initialized CTC connection between a first channel and a second channel is provided in a computing environment in which a CTC CU function can be provided in either channel after initialization of the CTC connection and can move from one channel to the other after re-initialization of the connection. After initialization, a newly formatted CDR having a device NED and a specific NEQ is stored. After re-initialization, a current CDR with the same format is obtained. The re-initialized CTC connection is validated if the stored set of NED and NEQ values match the current values, in any order.

摘要： A method and apparatus for determining common usage of elements among at least two channels in a data processing system having an arbitrary hardware element hierarchy including multiple channel paths over which data is transmitted. An internally executed initialization program builds a bit mask for channel paths to be compared wherein the bit masks describe the hierarchy of the hardware elements in the channel paths to be compared. A compare program provides a comparison result whose value reflects the impact of the failure of hardware elements that are common to the channel path being compared. The comparison results contains multiple bits, with set bits representing each element which is common to the hardware element common to the channel paths being compared. The impact of a failure of a common hardware element is greater the more significant the bit position of that component resides in the comparison results.

摘要： Disclosed is a method and computer program device for dynamically managing the assignment of alias addresses to base addresses referencing an input/output (I/O) device, such as a direct access storage device (DASD). Two distinct methods are disclosed. In one method, alias addresses are assigned based on the performance of the I/O devices. In this method, alias addresses are assigned to highly utilized devices, as indicated by device performance data, in order to maximize the efficient utilization of I/O device resources. In a second method, workload management principles are utilized to assign alias addresses. In this method, a correlation is made between each I/O device and the service classes utilizing each device. As in the first method, performance data is generated for each I/O device. Alias addresses are assigned to I/O devices experiencing queue delays as indicated by their performance data, if the device is associated with a service class that has failed to meet one or more processing goals. These methods may operate on a single host, or in a multi-host environment. The methods may be operated individually, or concurrently. Methods are disclosed to manage contention between concurrently operating assignment methods, and between multiple hosts concurrently operating one or more assignment methods.

摘要： An exemplary embodiment is a method for creating and identifying different kinds of groups of cooperating system images within a single machine, a single central processor complex (CPC) where each kind of group has a different functional purpose. Such a collection of cooperating system images is referred to as a logical partition cluster (LPC). An LPC is created or identified using a diagnose instruction. The diagnose instruction includes a subcode field designating a function to be performed and a logical partition cluster type field indicating the type of logical partition cluster said function is to be performed on.

摘要： Repositioning within an input/output device is accomplished without any knowledge of where the input/output device is currently positioned. The input/output device is repositioned to a predetermined position, in order for a program to be retried. The predetermined position is determined from a previously executed program. The previously executed program is scanned looking for commands. For each command found, a position identifier is adjusted based upon the type of command. When the scan and adjustments are complete, the position identifier represents the predetermined position used for repositioning the input/output device.

摘要： Control unit level reset operations in systems having switched point-to-point I/O interface topologies is accomplished by determining and storing channel path identification numbers (CHPID's) and control unit link addresses (CULA's) for each device in the system, scanning this stored data to find devices whose CHPID's and CULA's match the CHPID and CULA for a device or a control unit having a reported error, quiescing devices with such matching CHPID's and CULA's, issuing a control unit level reset command and reactivating the quiesced devices. For systems having both multidropped and switched point-to-point topologies, provision is made for preliminarily determining whether a given control unit reset can be performed on the control unit level.

摘要： An I/O request time limit value is set in a request-based, device-based, data-set-based, or workload-based time limit field, for transactions performing I/O operations to I/O devices in a data processing system. A scan routine compares the total time for the I/O request (including waiting time and retry time) against the appropriate time limit(s), and terminates the I/O request if the time limit is exceeded. If an active I/O request is interrupted as a result of an I/O error, retry is prohibited if the total I/O request time (including retry time) exceeds the appropriate time limit, or is within a threshold value of the appropriate time limit.

摘要： Provides a software-to-software interface and a software-to-hardware interface between software users and a hardware ADM facility (ADMF) in a data processing system. Such software user presents only virtual addresses to the software-to-software interface in a MSB list. The user list defines virtual address spaces, including a "hiperspace", in a manner that represents physical backing media as different random-access electronic storages, such main storage (MS) and expanded storage (ES). The real data transfers are within or between the backing storages. The user list is transformed into an ADM operation block (AOB), which is assigned an ADM UCB in a UCB queue which is associated with an ADM subchannel. The software-to-hardware interface generates an ORB, containing the AOB address, as an operand of a SSCB instruction which is executed to queue the associated subchannel onto one of plural co-processor queues in the ADMF. The ADMF uses the AOB to perform the requested page moves, and generates an interruption upon completion of each request which is sent to the hardware-to-software interface to remove the associated ADMF request from the ADM software request queue and free the associated ADM UCB for use by another user request.
