Abstract: Provided is a method, system, and program for caching updates to one target storage device in a first and second memories, wherein the target storage device is one of a plurality of storage devices. A determination is made of an allocation of available space in the second memory to the storage devices, wherein a total of the allocation of the available space to all the storage devices exceeds one hundred percent of the available space in the second memory. An update to one target storage device is received and then a determination is made as to whether adding the update to the second memory will exceed the allocation of available space for the target storage device in the second memory. One copy of the update is written to the second memory if adding the update to the second memory will not exceed the allocation of available space for the target storage device.

Abstract: Disclosed is a system, method, and an article of manufacture for preferentially keeping an uncopied data set in one of two storage devices in a peer-to-peer environment when data needs to be removed from the storage devices. Each time a data set is modified or newly created, flags are used to denote whether the data set needs to be copied from one storage device to the other. The preferred embodiments modify the timestamp for each uncopied data set by adding a period of time, and thus give preference to the uncopied data set when the data from the storage device is removed based on the least recently used as denoted by timestamp of each data set. Once the data set is copied, the timestamp is set back to normal by subtracting the same period of time added on when the data set was flagged as needing to be copied.

Abstract: Disclosed is a method, system, program, and data structure for queuing requests. Each request is associated with one of a plurality of priority levels. A queue is generated including a plurality of entries. Each entry corresponds to a priority level and a plurality of requests can be queued at one entry. When a new request having an associated priority is received to enqueue on the queue, a determination is made of an entry pointed to by a pointer. The priority associated with the new request is adjusted by a value such that the adjusted priority is associated with an entry different from the entry pointed to by the pointer. The new request is queued at one entry associated with the adjusted priority.

Abstract: Provided is a method, system, and program for providing status information in a system comprised of multiple components. A first processing node receives status information indicating a state of a system component and generates a status message indicating the state of the system component. The first processing node transmits the status message to a second processing node. The second processing node updates information maintained by the second processing node with the state of the system component indicated in the status message. Status information maintained by the second processing node is returned to a request for status.

Abstract: Disclosed is a system, method, and program for generating a data structure for use by a computer in determining a location of boundaries in text. The data structure is initialized and at least one regular expression is processed. Input characters in the at least one regular expression are then processed to determine at least one transition to at least one state. A determination is then made as to whether one input character would cause a non-deterministic transition. Additional states are added to the data structure to transform the non-deterministic transition to a deterministic transition.

Abstract: Disclosed is a method, system, and program for error checking raster objects including pixel information for a print job. A plurality of raster objects form the print job. A raster object is received including sequence information indicating an ordering of the raster object with respect to other raster objects in the print job. A determination is made from the sequence information as to whether the raster object is received in a correct order with respect to other raster objects in the print job. This ensures that the pixel information for the raster object is intended for a current pixel line being processed. An indication of error status is made if the sequence information indicates that the raster object was not received in the correct order with respect to the other raster objects in the print job.

Abstract: Disclosed is a method, system, and program for caching data. Data from a device, such as a volatile memory device or non-volatile storage device, is maintained in entries in a cache. For each entry in cache, a variable indicates both a time when the cache entry was last accessed and a frequency of accesses to the cache entry. The variable is used in determining which entry to denote from cache to make room for subsequent entries.

Abstract: Disclosed is a system, method, and program for linking to data from a document that includes a pointer to the data in a first storage device, which may be maintained in a network file server. A first request to access the data addressed by the pointer in the document is processed. Information on alternate storage devices, such as alternate file servers in the network, and data therein is processed to determine whether a copy of the data is present in a second storage device. A second request is submitted to access the copy of the data in the second storage device after determining that the information indicates that the second storage device includes the data. The accessed copy of the data, received in response to the second request, is then returned to the first request.

Abstract: Provided is a library system apparatus including an array of storage cells and a plurality of storage devices.

A gripper assembly includes extended members capable of engaging one storage device, movement electronics capable of moving the gripper assembly to the storage cells and engaging one storage device located within one storage cell, and a data interface. Data communication is enabled between the gripper assembly and storage device data interfaces when the gripper assembly is engaged with the storage device. Further, a library controller is in communication with the gripper assembly and executes logic to receive an input/output (I/O) request with respect to data in one target storage device in one storage cell and send commands to the gripper assembly to move to the storage cell including the target storage device and engage the target storage device in the storage cell.

Abstract: Disclosed is a method, system, program, and data structure for executing write operations. A first number of write operations is initiated. Performance data is gathered indicating a total time for a second number of the initiated write operations to complete. After at least one initiated write operation has completed, at least one additional write operation is initiated if a number of outstanding write operations is less than a maximum number of write operations. The maximum number of write operations is adjusted if the performance data meets at least one threshold.

Abstract: Disclosed is a method, system, and program for generating a blank side of a page in a print job. Bitmap data is received for at least one side of at least one page of a print job. The bitmap data for the at least one side is sent to a printer engine to control the printer to print the print job over a data path. For a blank side in one page in the print job, a command is issued to resend bitmap data for one side previously sent to the printer engine. A further command is issued to disable the data path to cause the transmission of white data to the printer engine. This disabling of the data path prevents the resent bitmap data from reaching the printer engine, which, in turn, causes the printer to produce the blank side in response to receiving the white data.

Abstract: Disclosed is a method, system, and program for accessing a shared file system that is accessible to a first computer. The shared file system includes files in at least one file format compatible with at least one application program installed on the first computer.

Abstract: Disclosed is a system, method, and program for magnifying displayed content downloaded from a server over a network. Information is received indicating selection of a region of the displayed content to magnify. A determination is made of at least one region of the selected region including image content. The server maintains a high resolution file version and a low resolution file version of the image content. A determination is then made as to whether the selected image content from the displayed image file is the low resolution file version. If so, a command is generated to retrieve from the server specific byte locations from the high resolution file version including the image content in the selected region. The specified bytes are less than all the image data bytes in the high resolution version of the file if the image content in the selected region comprises less than all of the image content maintained in the high resolution version of the file.
