Abstract: A method of providing optometric parameters for an optometric procedure includes locating patient identification information on a central data storage by transmitting a search query from a computing device communicating with the central data storage. The search query generates a result set containing at least one patient having patient identification information substantially matching the search query. From the result set, a patient undergoing the optometric procedure is selected. An input form for this patient is then displayed with input fields corresponding to each of the optometric parameters. A qualified collector obtains the measurement values for the optometric parameters and inputs them into respective input fields. A data record containing the measurement values and the patient identification information is generated and transmitted to the central data storage.

Abstract: In the described systems and methods for information lifecycle cross-system reconciliation, a number of reconciliation indicators for a certain type of data are defined. A first set of values of the reconciliation indicators are calculated at a first computer system based on data stored in a memory of the first computer system. A second set of values of the reconciliation indicators are calculated at a second computer system based on data transferred from the first computer system. The two sets of values are received at reconciliation cockpit and stored in a reconciliation data structure. Further, the reconciliation data structure is examined to identify inconsistency between the data stored in the memory of the first computer system and the data transferred to the second computer system. If such an inconsistency is identified, the data transfer is cancelled. If inconsistency is not identified, the data transfer is confirmed.

Abstract: The present invention provides tools and techniques for distinguishing a file from any or all copies of the file that may exist. One method ascertains (204) the actual physical location of the file (512) and associates (214) that physical location with the file as the claimed physical location (516) of the file. The file's originality status may then be determined (104) by finding (304) the location claim, reading (306) from it the claimed physical location associated with the file, ascertaining (308) the actual physical location of the file, and comparing (310) the locations. If the claimed and actual locations are identical, then the file is the original file it claims to be. If there is disparity between the claimed physical location recited for or by the file and the actual physical location of the file, then it is not the original file it claims to be.

Abstract: Methods and systems for efficient file replication are provided. In some embodiments, one or more coarse signatures for blocks in a base file are compared with those coarse signatures for blocks of a revised file, until a match is found. A fine signature is then generated for the matching block of the revised file and compared to a fine signature of the base file. Thus, fine signatures are not computed unless a coarse signature match has been found, thereby minimizing unneeded time-consuming fine signature calculations. Methods are also provided for determining whether to initiate a delta file generation algorithm, or whether to utilize a more efficient replication method, based upon system and/or file parameters. In accordance with additional embodiments, the lengths of valid data on physical blocks are obtained from physical block mappings for the files, and these lengths and mappings are utilized for delta file generation, to minimize unnecessary signature computations.

Abstract: A nonvolatile system memory of a server of a network file computer system temporarily stores data received from client computers prior to the data being stored on a mass storage device. A single copy of the data and pointers which corresponds to the memory addresses of the data are stored in a temporary memory storage portion, preferably partitioned from nonvolatile system memory. The pointers are used to access the data to enable the transfer and writing of the data from the temporary memory storage to the mass storage device. Writing the data occurs during the normal operation of the network file computer system or after an unclean shutdown. The use of the pointers increases the performance of the network file computer system by conserving system memory storage space and reducing system memory traffic.

Abstract: A conductor transmits a commit processing request to directors in response to a commit request received from an application. Upon receipt of a response to the commit processing request from any one of the directors, the conductor notifies the application of a successful commit. If there is a pending transaction due to a failure in a director, the conductor instructs the director to process the pending transaction upon recovery from the failure. If a failure occurs in the conductor during transmission of the commit processing request and the commit processing request is not received by any of the directors, the conductor inquires the director whether there is a pending transaction after recovery from the failure, and instructs the director to process the pending transaction based on a processing result of the pending transaction obtained from another director.

Abstract: A computer system includes a database representing various transactions performed by the system. The number of transactions can be quite large. They may form the basis of analytical processing performed by the computer system, whose results may be used by subsequent stages of analytical processing. When data errors are corrected, the present invention permits a correction server to identify data entities (analytical results or the like) that may now be inconsistent due to the correction. The computer system may include a data flow manager that monitors data flows throughout the system and generates a read history therefrom, identifying reading entities as being dependent on entities from the database. When corrections are made, the corrected database entities are identified in a corrected entity log. If a comparison between the corrected entity log reveals a match with an entry in the read history log, the dependent entity may be identified as possibly inconsistent.

Abstract: Systems and methods for automating and increasing the efficiency of access to data using inheritance of access rules within an organization based upon the relationship of positions within the organization and the roles associated with the positions. In one embodiment, a role structure is used in conjunction with a hierarchical organization structure to allow access rules to be inherited by some of the positions from other positions based upon the relationship of positions within the organization and the roles associated with the positions. Access rules can be applied across equivalent or similar positions, yet differentiated between distinct portions of the organization and the distinct roles associated with the positions. Consequently, particular access rules are not necessarily inherited by all of the positions subordinate to a particular position with which the rule originates, and are not necessarily inherited by all of the positions that are associated with a particular role.

Abstract: A system and method for performing File System checKing (FSCK) allows a file system to be accessed while the file system is being checked for consistency in the background.

Abstract: A client transmits, to a server, an instruction to copy a certain file for update, and receives the copied file. Upon update of the received file, the client generates update information on the update of the received file, and transmits the generated update information to the server. The server extracts a file containing a part related to the received update information, and judges whether or not the extracted file has been copied and then transmitted to a different client. If judging that the extracted file has been copied and transmitted to the different client, the server transmits warning information to the different client to which the extracted file has been transmitted, the warning information indicating that the file is updated in the client other than the different client.

Abstract: Provided are a method, system, and program for using a heartbeat signal to maintain data consistency for writes to source storage copied to target storage. A copy relationship associates a source storage and target storage pair, wherein writes received at the source storage are transferred to the target storage. A determination is made whether a signal has been received from a system within a receive signal interval. A freeze operation is initiated to cease receiving writes at the source storage from an application in response to determining that the signal has not been received within the receive signal interval. A thaw operation is initiated to continue receiving write operations at the source storage from applications after a lapse of a freeze timeout in response to the freeze operation, wherein after the thaw operation, received writes completed at the source storage are not transferred to the target storage.

Abstract: The present invention provides a computer implemented method for truncating a file in a file system. The file system receives a request to truncate a file to a target size, the file having a first inode. The file system creates a second inode to a transient directory, wherein the second inode holds a plurality of in-progress entries. The file system sets a target size in the first inode. The file system writes a truncate entry to a journal, the truncate entry comprising a predetermined size. The file system truncates the file by up to the predetermined size. The file system determines that the file is above the target size. Responsive to a determination that the file is above the target size, the file system repeats the truncating step and the determining step. Responsive to a determination that the file is not above the target size, the file system applies the in-progress entries from the transient directory.
