The Oracle, ODBC, and DB2 CLI Template Library (OTL) is a C++ library for database access, written by Sergei Kuchin. The OTL exists since 1996. It consists of a single header file. Besides Oracle, the OTL supports DB2 (natively), and various database systems now, [when?] directly or indirectly, via ODBC.
ACFS [2] is a standard-based POSIX (Linux, UNIX) and Windows cluster file system with full cluster-wide file and memory mapped I/O cache coherency and file locking. ACFS provides direct I/O for Oracle database I/O workloads. ACFS implements indirect I/O however for general purpose files that typically perform small I/O for better response time.
Oracle Database (commonly referred to as Oracle DBMS, Oracle Autonomous Database, or simply as Oracle) is a proprietary multi-model [4] database management system produced and marketed by Oracle Corporation. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database ...
A lock value block is associated with each resource. This can be read by any process that has obtained a lock on the resource (other than a null lock) and can be updated by a process that has obtained a protected update or exclusive lock on it. It can be used to hold any information about the resource that the application designer chooses.
In AmigaOS, a lock on a file (or directory) can be acquired using the Lock function (in the dos.library). A lock can be shared (other processes can read the file/directory, but can't modify or delete it), or exclusive so that only the process which successfully acquires the lock can access or modify the object.

Having a Flickr user send you the declaration of consent through Flickr mail may not be enough proof for VRT, but having them change the license is enough proof.

Flush: Snooped request that indicates that an entire cache block is written back to the main memory by another processor. FlushOpt: Snooped request that indicates that an entire cache block is posted on the bus in order to supply it to another processor (Cache to Cache transfers). (Such Cache to Cache transfers can reduce the read miss latency ...
Berkeley DB, the C database library that is the subject of this article; Berkeley DB Java Edition, [15] a pure Java library whose design is modelled after the C library but is otherwise unrelated; Berkeley DB XML, [16] a C++ program that supports XQuery, and which includes a legacy version of the C database library
