摘要： A fast crash safe method and apparatus for enforcing mutually exclusive access to shared resources in a computer system through the use of semaphores. The acquisition and release of the semaphores is implemented at the user process level. An overestimate and underestimate of semaphore ownership are maintained in memory by library provided semaphore acquisition and release code. A cleanup routine reconciles the overestimate and underestimate to determine the ownership status of the semaphores.

摘要： A method of detecting and recovering from data corruption of a database is characterized by the step of protecting data of the database with codewords, one codeword for each region of the database; and verifying that a codeword matches associated data before the data is read from the database to prevent transaction-carried corruption. A deferred maintenance scheme is recommended for the codewords protecting the database such that the method of detecting and recovering from data corruption of a database may comprise the steps of protecting data of the database with codewords, one codeword for each region of the database; and asynchronously maintaining the codewords to improve concurrency of the database. Moreover, the database may be audited by using the codewords and noting them in a table and protecting regions of the database with latches. Once codeword values are computed and checked against noted values in memory, a flush can cause codewords from outstanding log records to be applied to the stored codeword table.

摘要： For use with a database of data records organized into components, the database stored in a memory, a processing system for, and method of, physically versioning the database. In one embodiment, the processing system includes: (1) a component copier that creates a physical copy of an original component to be affected by an update transaction to be applied to the database, and that causes pointers in nodes of the physical copy to point to other nodes in the physical copy, (2) a data updater, associated with the component copier, that applies the update transaction to the physical copy to create therefrom a new physical version, the original component remaining unaffected by the update transaction and (3) a pointer updater, associated with the data updated, that employs an atomic word write to revise a component pointer, associated with the database, to cause the pointer to point to the new physical version.

摘要： A method of detecting and recovering from data corruption of a database is characterized by the step of logging information about reads of a database in memory to detect errors in data of the database, wherein said errors in data of said database arise from one of bad writes of data to the database, of erroneous input of data to the database by users and of logical errors in code of a transaction. The read logging method may be implemented in a plurality of database recovery models including a cache-recovery model, a prior state model a redo-transaction model and a delete transaction model. In the delete transaction model, it is assumed that logical information is not available to allow a redo of transactions after a possible error and the effects of transactions that read corrupted data are deleted from history and any data written by a transaction reading Ararat data is treated as corrupted.

摘要： A method and apparatus are provided for composing XSL transformations with XML publishing views. XSL transformations are performed on XML documents defined as views of relational databases. A portion of a relational database can be exported to an XML document. An initial view query defines an XML view on the relational database and an XSLT stylesheet specifies at least one transformation. The initial view query is modified to account for an effect of the transformation and the modified view query is applied to the relational database to obtain the XML document. When the modified view query is evaluated on a relational database instance, the same XML document is obtained as would be obtained by evaluating the XSLT stylesheet on the original XML view.
