摘要:
Character data for a plurality of characters on which character recognition is being performed is received for processing. The character data includes character assignments and character locations. A reference location is defined in relation to a location of one of the characters, and the character assignments are resolved into one or more groupings according to a distance of the characters from the reference location.

A method of transferring a transaction workload of a primary process pair. The primary pair has access to a stable storage volume for storing data items and a log for storing transaction processing updates to data items. A backup process pair is established for the primary pair and information is transferred thereto so that it can take over for the primary pair should that pair fail. Additionally, a lock table is maintained and update records are written to the log by the primary pair. The update records include any locks from the lock table that related to the update records. When a failure of the primary pair occurs, the storage volume is locked, and the backup pair reads the log to reconstruct a lock table. Once the locks have been reconstructed, the lock on the storage volume is released and the backup pair operates to process the workload.

In a multiple processing system or cluster, a pair of processes, assuming the role of a primary process and a backup process to the primary process, are replaced on-line by stopping the backup process; creating the replacement backup process; checking to ensure compatibility between the primary and replacement backup processes so that communication between them is possible and information sent by the primary process to the replacement will be correctly received and handled; providing the replacement backup process with that state of the primary process needed in order to take over the function and operation of the primary process; switching roles so that the replacement backup process now takes over the function and operation of the primary, and the primary becomes the backup; and repeating the steps of creating, checking, providing and switching, to conclude with a newly-installed replacement primary process and a replacement backup process, completing the on-line replacement of the process pair.

Provided is a method for scheduling activities. The method includes partitioning tasks provided for scheduling. The partitioning is accomplished by receiving at least one task including at least one data type. The data type is reviewed to determine at least one scheduling criteria and the task is routed to a queue based on the determined scheduling criteria. Each queue also has at least one queue characteristic. The method also includes scheduling the partitioned tasks. The scheduling is accomplished by retrieving the at least one task from the queue in response to a trigger. The retrieved task is routed to at least one scheduler. In a first instance the routing is based on the queue characteristic. In a second instance the routing is based on at least one scheduler characteristic. A scheduling system for performing this method is also provided.

Methods for the electrolytic preparation of tin coated metals are disclosed. Organic polybasic acids, such as methanedisulfonic acid [CH2(SO3H)2], 1,3-acetonedisulfonic acid [CO(CH2SO3H)2], anhydrides, and their water soluble salts, and mixtures thereof may be used as the electrolyte in the plating process or as the flux in the reflow process. Acetone, gamma-butyrolactone, or a mixture thereof, may be applied to a tin plated surface, either before or after reflow. The methods of the invention produce plated material that is free of blue haze.

A storage subsystem provides redundancy protection for data associated with files stored in a storage subsystem. A request is received to change the redundancy protection for data associated with at least one of the files, where the request identifies the data for which the redundancy protection is to be changed. The redundancy protection for the data identified by the request is changed, while the redundancy protection for a remainder of the data associated with the files stored in the storage subsystem is maintained unchanged.

Provided is a problem solving system. More specifically, the problem solving system provides an interface operable to receive user supplied input data, the input data having at least one user defined characteristic. The system provides an algorithm pool having a plurality of pre-defined algorithms, each algorithm having at least one associated algorithm characteristic.
