MY'STORY

The MOVE Fire

This is a personal recollection on the Move fire on May 13, 1985 Philadelphia police fired thousands of rounds at the MOVE house, city officials approved dropping an explosive device on the roof, the resulting fire was allowed to burn, 11 people—including five children—died, and 61 homes were destroyed. Philadelphia City Council later called it a “brutal attack carried out by the City of Philadelphia on its own citizens” and acknowledged that no individual faced criminal consequences for the bombing. One timeline correction worth preserving for the BHP record: the major previous MOVE-police confrontation was August 8, 1978, about seven years before the bombing, not a year or two earlier. Officer James Ramp was killed, other police and firefighters were wounded, nine MOVE members were later convicted, and television cameras recorded police beating Delbert Africa during his arrest. The 1985 MOVE Commission later specifically criticized city planners for failing to adequately use lessons from that 1978 confrontation. And that actually strengthens the point you’re making: 1985 did not happen without precedent or institutional memory. There had already been a deadly confrontation with MOVE, years of conflict, negotiations and police involvement before Osage Avenue.

Database machine

A database machines or back end processor is a computer or special hardware that stores and retrieves data from a database. It is specially designed for database access and is tightly coupled to the main (front-end) computer(s) by a high-speed channel,[1] whereas a database server is a general-purpose computer that holds a database and it's loosely coupled via a local area network to its clients.

Database machines can retrieve large amount of data using hundreds to thousands of microprocessors with database software. The front end processor asks the back end (typically sending a query expressed in a query language) the data and further processes it. The back end processor on the other hand analyzes and stores the data from the front end processor. Back end processors result in higher performance, increasing host main memory, increasing database recovery and security, and decreasing cost to manufacture.

History

[edit]

Britton-Lee (IDM), Tandem (Non-Stop System), and Teradata (DBC) all offered early commercial specialized database machines.[2] A more recent example was Oracle Exadata.

X-machine

The X-machine (XM) is a theoretical model of computation introduced by Samuel Eilenberg in 1974. The X in "X-machine" represents the fundamental data type on which the machine operates; for example, a machine that operates on databases (objects of type database) would be a database-machine. The X-machine model is structurally the same as the finite-state machine, except that the symbols used to label the machine's transitions denote relations of type X→X. Crossing a transition is equivalent to applying the relation that labels it (computing a set of changes to the data type X), and traversing a path in the machine corresponds to applying all the associated relations, one after the other.

Oracle Exadata

Oracle Exadata (Exadata) is a computing system optimized for running Oracle Databases. Exadata is a combined database machine and software platform that includes scale-out x86-64 compute and storage servers, RoCE networking, RDMA-addressable memory acceleration, NVMe flash, and specialized software. Exadata was introduced in 2008 for on-premises deployment, and since October 2015, via the Oracle Cloud as a subscription service, known as the Exadata Database Service on Dedicated Infrastructure, and Exadata Database Service on Exascale Infrastructure. Exadata Cloud@Customer is a hybrid cloud (on-premises) deployment of Exadata Database Service. Starting December, 2023, Exadata Database Service became available for Microsoft Azure, Google and AWS public clouds within the Oracle Database@Azure, Oracle Database@Google Cloud and Oracle Database@AWS multicloud partnerships.

Oracle Zero Data Loss Recovery Appliance

The Oracle Zero Data Loss Recovery Appliance (Recovery Appliance or ZDLRA) is a computing platform that includes Oracle Corporation (Oracle) Engineered Systems hardware and software built for backup and recovery of the Oracle Database. It performs continuous data protection, validates backups, automatically resolves many issues, and provides alerts when backups fail validation. It is designed for Oracle databases and works only on Oracle databases. It is considered a 3rd party backup and recovery product. It was introduced in 2014 as part of Oracle Corporation's family of "Engineered Systems" and shares components with the Oracle Exadata Database Machine, with an additional layer of software that provides specific features for backup, recovery, replication, monitoring, and management. Like the Oracle Exadata Database Machine, it is periodically refreshed as a new interoperable and expandable “generation” based on newer hardware technology at the time of release. In September 2019, the Recovery Appliance X8M introduced a 100 Gbit/s internal network fabric based on RoCE (RDMA over Converged Ethernet), replacing the InfiniBand fabric used in previous Recovery Appliance generations. The Recovery Appliance elastic configuration starts with a "Base Rack" that can be increased to a "Full Rack" or larger "multi-rack" configuration. A Base Rack is capable of managing over 207 terabytes of backup data, while a Full Rack can manage over 1.26 petabytes. Multi-Rack configurations of up to 18 racks wide can manage more than 22 petabytes of data. Since Recovery Appliance only needs to store data that has changed, the actual size of databases that are protected can be many times larger than the storage capacity of a Recovery Appliance.

TOPIC OF THE DAY

Greenwood / Black Wall Street

Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
