PTP application
PTP application. A collection of software components that perform transaction processing
for CICS applications in the Guardian environment on Tandem NonStop systems. See
also Customer Information Control System (CICS) and Parallel Transaction Processing
(PTP) Services for the CICS API product.
PTP Services product. See Parallel Transaction Processing (PTP) Services for the CICS
API product.
PTP server. A server in the PTP transaction processing environment. See also Customer
Information Control System (CICS), PTP transaction processing environment, and
Parallel Transaction Processing (PTP) Services for the CICS API product.
PTP transaction processing environment. An environment that supports the CICS/ESA
3.3 command-level application program interface (API) and provides run-time services
for CICS applications in the Guardian environment. The PTP environment provides the
Tandem fundamentals for CICS applications. See also Customer Information Control
System (CICS), Parallel Transaction Processing (PTP) Services for the CICS API
product, and PTP application.
reduced instruction-set computing (RISC). A processor architecture based on a relatively
small and simple instruction set, a large number of general-purpose registers, and an
optimized instruction pipeline that supports high-performance instruction execution.
See also complex instruction-set computing (CISC).
relative pathname. An OSS pathname that does not begin with a slash (/) character.
A relative pathname is resolved beginning with the current working directory. See also
OSS pathname, absolute pathname, and current working directory.
Remote Duplicate Database Facility (RDF). The Tandem software product that assists in
disaster recovery for OLTP production databases, monitors database updates audited
by the TMF subsystem on a primary system, and applies those updates to a copy of
the database on a remote system.
Remote Server Call (RSC). A Tandem software product that facilitates client/server
computing, allowing personal computer (PC) or workstation applications running under
Microsoft Windows software or the MS-DOS or OS/2 operating system to access
Pathway server classes and Guardian processes. Transactions are transmitted from
the PC or workstation application (the client) to a Pathway application running on a
Tandem NonStop system (the server) by means of a supported communications
protocol, such as NETBIOS, TCP/IP, or an asynchronous connection.
reply message. The part of an interprocess communication message that is formatted by a
server and returned to the original requester. The message contains the results of the
server’s work. See also request message.
reply translation header. A group of header fields that the Pathway translation server for
the NonStop TUXEDO system inserts at the beginning of each reply message it relays
from the application service to a SCREEN COBOL or Pathsend requester. This header
