NonStop SOAP 4.1 User's Manual

D
Data Definition
Language (DDL).
The set of data definition statements within the Structured Query Language (SQL). An HP product
for defining data objects in Enscribe files on NonStop™ systems and translating object definitions
into source code.
data type A categorization of values, operations, and arguments that usually cover both behavior and
representation.
deployment
directory
This is an OSS directory that can be considered as the working directory where all the services,
modules, and log files are available.
deployment script A script file used to deploy the NonStop SOAP 4 server and setup the deploy environment.
directory A type of Open System Services (OSS) special file that contains directory entries that name links
to other files. No two directory entries in the same directory can have the same name.
DLL A DLL is a library that contains code and data, which can be used by more than one program
at the same time.
E
element The basic unit of information in an XML document. An element has a name and can have content
and attributes.
envelope The elements of a SOAP message that precede and follow the body of the message.
environment
variable
An element of a system or product-specific configuration file used to specify the path to a
processing component or to control some aspect of system or product operation. For example,
you use an environment variable in the OSS profile file to specify the location of the NonStop
configuration file.
Event Management
Service (EMS)
A part of DSM used to provide event collection, event logging, and event distribution facilities.
It provides for different descriptions of events for people and for programs, lets an operator or
application select specific event message data, and allows for flexible distribution of event
messages within a system or network. EMS has an SPI-based programmatic interface for reporting
and retrieving events.
event message A special kind of SPI message that describes an event occurring in the system or network. Event
messages are collected, logged, and distributed by EMS.
F
file An object to which data can be written or from which data can be read. A file has attributes,
such as access permissions and a file type. In the Open System Services (OSS) environment, file
types include regular file, character special file, block special file, FIFO, and directory.
file descriptor A non-negative integer that uniquely identifies a single open of a file to a running process. Each
file descriptor is associated with an open file description that contains data about the file.
file identifier (file
ID)
In the OSS environment, a portion of the internal information used to identify a file in the OSS
file system. In the Guardian environment, the portion of a file name following the subvolume
name. The two identifiers are not comparable.
file name In the Guardian environment, the set of node name, volume name, subvolume name, and file
identifier characters that uniquely identifies a file. This name is used to open a file and thereby
provide a connection between the opening process and the file. In the Open System Services
(OSS) environment, a component of a pathname containing any valid characters other than a
slash (/) or a null.
file system (1) In the Guardian environment, the application program interface for communication between
a process and a file. A file can be a disk file, a device other than a disk, or another process. (2)
In the OSS environment, a collection of files and file attributes. A file system provides the
namespace for the file serial numbers that uniquely identify its files.
File Transfer
Protocol (FTP).
The Internet standard, high-level protocol for transferring files from one machine to another.
Usually implemented as application-level programs, FTP uses the TELNET and Transmission Control
Protocol (TCP) protocols. The server side requires a Web client to supply a login identifier and
password before it will honor requests.
