  • Methodology providing high-speed shared memory access between database middle tier and database server
    Patent number: 6687702
    Abstract: A multi-tier database system is modified such that a middle-tier application server (EJB server) and a database server run on the same host computer and communicate via shared-memory interprocess communication. The system includes a database (e.g., JDBC) driver thread that attaches to the database server, specifically by attaching to the database server's shared memory segment. Operation of the JDBC driver is modified to provide direct access between the middle tier (i.e., EJB server) and the database server, when the two are operating on the same host computer.

  • DATABASE SYSTEM WITH IMPROVED METHODS FOR ASYNCHRONOUS LOGGING OF TRANSACTIONS
    Publication number: 20040010499
    Abstract: A database system providing improved methods for asynchronous logging of transactions is described. Log records are created describing changes to a database made by a transaction. When a command committing changes to the database for the transaction is received, a logging request is placed in a queue. An asynchronous logging service removes requests from the queue and transfers log records from the transaction to a shared cache. The shared cache stores log records before they are written to the transaction log. The logging service writes log pages containing log records for the transaction from the cache to the transaction log. After all log pages in the cache for the transaction have been written to the transaction log, changes to the database made by the transaction can be committed to the database.
