ClearPath IX Systems Installation and Configuration Guide

Glossary
Open/OLTP Pathway
An Open/OLTP middleware component that provides applications in the Intel (UnixWare
or Windows NT) environment of a ClearPath IX server with a gateway to the Open/OLTP
Transaction Manager in the OS 2200 environment. This allows Windows NT or UnixWare
applications to execute transactions against OS 2200 databases.
Open Programming Environment (OPE)
The Unisys implementation of the SVR4 environment. OPE is not a product but rather an
optional programming environment available in the OS 2200 operating environment of a
ClearPath IX server.
Open Systems Interconnect Transaction Processing (OSI TP)
An ISO standard (ISO/IEC 10026-2) for protocols and services that establish dialogues and
pass messages between client programs and service routines on different computers.
operations database (ODB)
A database populated with information unloaded from the Site Configuration Management
System (SCMS) database. The ODB contains configuration information needed by the OS
2200 Exec to operate 2200 Series component hardware.
OSI
Abbreviation for Open Systems Interconnection.
OSI-MHS
Abbreviation for Open Systems Interconnection Message Handling System.
P
Packet Internet Groper (PING)
A command used to verify connections to one or more remote hosts. The PING utility uses
the Internet Control Message Protocol (ICMP) echo request and echo reply packets to
determine whether a particular IP system on a network is functional. The PING utility is
useful for diagnosing IP network or router failures.
parity
An extra bit added to a group of bits (for example, a byte or a word) to reveal errors in data
storage or transmission.
partition databank (PDB)
A data structure passed by the System Control Facility (SCF) to the Exec that contains all
the necessary information for the Exec to operate the hardware in the partition. The PDB
is used to build the I/O, tape translator, and other sections of the master configuration
table (MCT). The partition databank is created by the SCMS partitioning function.
