Abstract: Disclosed is a system for reassigning addresses. A first processing unit, such as a storage controller, provides at least two base addresses for addressing devices, such as volumes of a direct access storage device (DASD) and a plurality of alias addresses. An alias address associated with a base address provides an address for addressing the device addressed by the base address. The first processing unit processes a command transmitted from a second processing unit, such as a host system that accesses the DASD through the storage controller, to reassign an alias address from a first base address to a second base address. The first base address addresses a first device and the second base address addresses a second device. The first processing unit then indicates that the alias address to reassign is not associated with the first base address and is associated with the second base address. The second device addressed by the second base addresses is capable of being addressed by the reassigned alias address.

Abstract: A data processing controlled display system for the interactive display and control of a hierarchical tree of elements or objects which are selectable to display detailed views of the attributes of the child objects of the selected parent object. The invention is directed to parent objects of which the child objects are different object types. Upon the selection of such a parent object, its child objects are displayed in a plurality of separate screen regions, each respectively displaying the attributes of one of said different types of child objects. The different types of child objects may come from different levels in the hierarchy. The invention is also applicable to the hierarchical trees used in object oriented programming and particularly to situations in object oriented programming where the selected parent object is of a container class.

Abstract: Disclosed is a system for queuing elements, such as print jobs. A processing unit receives an element that is associated with a first factor and a second factor, such as data type and a priority within the data type, that indicates a priority of the element. For each first factor and second factor pair, an entry point addresses a point in the queue associated with the first factor and second factor. The processing unit locates an entry point addressing a point in the queue associated with a first factor and second factor that matches the first factor and second factor associated with the received element. The processing unit then inserts the received element in the queue at the entry point.

Abstract: Disclosed is a cache management scheme using multiple data structure. A first and second data structures, such as linked lists, indicate data entries in a cache. Each data structure has a most recently used (MRU) entry, a least recently used (LRU) entry, and a time value associated with each data entry indicating a time the data entry was indicated as added to the MRU entry of the data structure. A processing unit receives a new data entry. In response, the processing unit processes the first and second data structures to determine a LRU data entry in each data structure and selects from the determined LRU data entries the LRU data entry that is the least recently used. The processing unit then demotes the selected LRU data entry from the cache and data structure including the selected data entry. The processing unit adds the new data entry to the cache and indicates the new data entry as located at the MRU entry of one of the first and second data structures.

Abstract: The system, method, and program of this invention is capable of taking as input a three dimensional colorant (e.g., CMY, L*a*b*) and determining an equivalent combination of colors made up of four or more colorants that are used by a given printer. A plurality of patches are printed having predetermined known combinations of varying percentages of three primary colors (e.g., CMY). Another set of patches are printed having predetermined varying percentages of a fourth color (e.g., black). The L*a*b* of these patches are measured. An inversion program is used to determine equivalent CMY component percentage values for the varying percentages of the fourth component based upon similar actually measured L*a*b* values. These determined CMY component percentage values and the known percentages of CMY are used to substitute the fourth colorant (K) for each of the original CMY combinations, known as fourth colorant substitution or black substitution.

Abstract: Disclosed is a method, system, and program for converting an externally defined four dimensional colorant, e.g., CMYK, to an equivalent four dimensional colorant, e.g., C'M'Y'K, having components of a printer. A measurement is made of first color values, e.g., L.sup.* a.sup.* b, of a first set of patches having predetermined combinations of varying percentages of three primary colors, e.g., CMY, printed by the printer. Each combination of known CMY values are correlated with corresponding color values, e.g., L.sup.* a.sup.* b, as input to a first inversion program for determining CMY values for any given color value (L.sup.* a.sup.* b). A measurement is also made of second color values, e.g., L.sup.* a.sup.* b, of a second set of patches having predetermined varying percentages of a fourth colorant (K) printed by the printer. The first inversion program is used to determine CMY values corresponding to the color values, L.sup.* a.sup.* b, for the varying percentages of the fourth colorant (D).

Abstract: Disclosed is a system for isolating errors in a remote copy system. A first controller writes data to a volume in a first direct access storage device (DASD) and maintains a copy of the data in a cache. The first controller transfers the data in the cache to a host system via a first communication line. The host system then transfers the data transferred from the first controller to a second controller via a second communication line. The second controller writes the data transferred from the host system to a volume in a second DASD. A volume pair is comprised of a volume in the first DASD and a volume in the second DASD, wherein for each volume pair, the second DASD volume backs-up data stored in the first DASD volume. If an error related to a volume pair is detected, then the operation of transferring the data in the cache for the volume pair related to the error to the second controller via the host system is suspended. Information on the detected error is written to a first data set.

Abstract: Disclosed is a system, typically implemented in a storage controller, for extracting data from a device storing data in a first format, such as the count-key-data (CKD) format. The first format is comprised of a plurality of tracks. Each track has at least one data area and each data area is comprised of at least one addressable block of data. A request from a host system for an address of a block of data in a second data format, such as the Fixed Block Architecture (FBA) format, is received. The system calculates a byte displacement value for the requested address. A data area in a track in the device having a byte displacement value less than the byte displacement value for the requested address is located. A byte location offset is then determined by subtracting the byte displacement value for the located data area from the byte displacement value for the requested address. The system then determines a location in the located data area of a block of data at the byte location offset.
