PARALLEL Processing Connection, January meeting notice

January 12th ... Boris Klots starts off the new year with a detailed description of the Oracle relational database system. This important application can be used in an exclusive or shared mode, i.e. one or multiple Oracle instances, respectively. The shared mode allows concurrent direct reads and writes to all the data in the database by multiple users from multiple instances of Oracle and is implemented by the Oracle Parallel Server (OPS) option. The OPS shared disk cluster architecture provides high availability, dynamic partitioning/load balancing, and enhanced throughput by taking advantage of the aggregate CPU and memory resources of the cluster. The main challenge of a shared architecture is providing data coherency for the independent users of the system. This is accomplished by Oracle's sophisticated locking schemes: row locks at the transaction level, instance locks, and global locks across instances. Boris plans to discuss these details and OPS' important failure detection/recovery .methods. The main meeting starts promptly at 7:30PM at Sun Microsystems at 901 San Antonio Road in Palo Alto. This is just off the southbound San Antonio exit of 101. Northbound travelers also exit at San'Antonio and take the overpass to the other side of 101. A discussion of member projects currently underway and other issues of interest to entrepreneurs follows immediately thereafter at 9:15PM. Please be prompt; as usual, we expect a large attendance; don't be left out or left standing. There is a $12 fee for non-members and members will be admitted free. Yearly membership fee is $65. -- B.
