The section headed "!" contains entries beginning with digits, punctuation marks, and other special characters. However, filename extensions, although shown with their preceding periods (for example, .int), appear under their initial letters.

A

application container

A version of the run-time system modified to run in a special Enterprise Server mode.

application-managed service

A service in which the COBOL application manages its own transactions: the application issues its own COMMITs, ROLLBACKS etc.

B

binary protocol

See BINP

BINP

A Micro Focus protocol for passing information between a J2EE connector and a service.

C

communications process

A process that accepts client requests arriving at multiple IP addresses and sends responses to them. Handles a variety of communications protocols and owns one or more service listeners.

configuration block

An area of memory containing configuration information such as environment variables and run-time tunables that the COBOL application needs to allow it to run successfully.

container-managed service

A service in which the application container manages transactions on behalf of the COBOL application: the application container connects to resources (files and databases) and issues COMMITs, ROLLBACKS on behalf of the application.

custom request handler

A request handler written by a user to meet specific application requirements not addressed by the Micro Focus request handlers.

D

DD

See deployment descriptor

deployment descriptor

A collection of definitions about how a service has been deployed.

Directory Server

The program in Enterprise Server that maintains information about enterprise server objects (enterprise servers themselves, services, service listeners, request handlers and implementation packages), distributes the information to the other Enterprise Server components and controls enterprise servers.

Directory Server journal

A file that records some of the activity occurring on the Directory Server.

Directory Server repository

The set of files that describes enterprise servers and the services, service listeners, request handlers and implementation packages associated with them.

E

enterprise server

A server that provides an execution environment for COBOL applications running as services.

Enterprise Server Administration

A user interface to the Directory Server that runs in a Web browser.

enterprise server console daemon

Parent of all processes in an enterprise server.

H

Handler

See request handler

I

implementation package

A collection of information about a COBOL application that is providing a service.

IDT

See interface definition table

interface definition table

A collection of information necessary to map a client request onto a COBOL program interface.

J

J2EE connector

See resource adapter

journal

See Directory Server journal

L

Listener

See service listener

M

MLDAP

A Micro Focus version of the LDAP, or Lightweight Directory Access Protocol. MLDAP enables program clients to locate services and other objects in the Directory Server repository.

P

package

See implementation package

program client

A client of the Directory Server that connects to it using its underlying MLDAP application programming interface, for example, to search for a specific service before sending a request.

R

repository

See Directory Server repository

request handler

A program that converts client requests into a call to a COBOL program providing a service and reconverts the response from the program into a form that the client can understand.

resource adapter

Software that enables Java code running on a J2EE application server to communicate with Enterprise Server.

run-time interface mapper

Software that runs in a service execution process and maps the input and output data of an exposed interface to the Linkage Section data of a COBOL application.

S

server monitor

Part of the Directory Server software that monitors whether or not enterprise servers are responding to client requests.

service

Access to specific business functionality, usually through an Internet connection.

service class

A property of a service that could be common to several services providing the same or similar functionality, enabling clients to search for a class of service rather than a specific service.

service execution process

One of a pool of processes belonging to an enterprise server, in which the COBOL application process providing a service is executed in response to a client request.

service listener

A communications gateway that monitors client requests arriving at a specific IP address.

sessions list

A list of all the Web browser client and program clients of the Directory Server.

Simple Object Access Protocol

See SOAP

SOAP

A industry-standard protocol for passing information to and from Web services that is based on XML. SOAP simply defines the format of the messages that are transmitted between machines. It works independently of any component model.

W

Web browser client

A client of the Directory Server that connects to it using the Enterprise Server Administration interface.
