NonStop SQL/MP
NonStop SQL/MP. See NonStop Structured Query Language/MP (NonStop SQL/MP).
NonStop Structured Query Language/MP (NonStop SQL/MP). The HP relational
database-management system that promotes efficient online access to large
distributed databases.
NonStop TCP/IP. A reliable communication protocol between NonStop systems and
workstations or other systems over an Ethernet connection.
NonStop Testing. The process of testing a software product to ensure that recovery
operations work as specified when errors are introduced.
NonStop Transaction Services/MP (NonStop TS/MP). An HP product for online
transaction processing on NonStop servers consisting of the PATHMON process, the
link manager process, the PATHCOM process and interface, and the Pathsend
procedures.
NonStop TS/MP. See NonStop Transaction Services/MP (NonStop TS/MP).
NonStop Tuxedo application. The collection of machines, servers and services, and
System /T components defined by a single configuration file in the NonStop Tuxedo
environment. See also NonStop Tuxedo transaction-processing environment and
Pathway application.
NonStop Tuxedo System /T. The HP implementation of the Tuxedo System /T component,
including the HP fundamentals of parallelism, availability, scalability, and manageability.
NonStop Tuxedo transaction-processing environment. An environment that provides the
API and transaction-monitor functions of the BEA Tuxedo transaction-processing
system in addition to the benefits provided by the HP core services: HP NonStop
operating system, NonStop Transaction Services/MP, and NonStop Transaction
Manager/MP. See also Pathway transaction-processing environment.
NonStop Tuxedo system. The HP implementation of the BEA Systems, Inc. Tuxedo
enterprise transaction-processing system. Major features include the use of HP core
services (NonStop TS/MP, TMF, NonStop operating system OSS) to provide the HP
fundamentals (scalability, availability, manageability) for Tuxedo applications.
nowait I/O. The ability of an application process to continue executing in parallel with
reading or writing operations; the application process runs concurrently with the file
operation. Programmers writing for a multithreaded environment use this technique
extensively. See also multithreaded process.
NSX. See Network Statistics Extended (NSX).
N+1 fault tolerance. A fault-tolerant design used in HP NonStop systems that provides one
more of a given module than the minimum necessary to do the job.
