Universal Data Mover Server for UNIX

Overview

This page provides the following information on Universal Data Mover (UDM) Server, specific to the UNIX operating system:

Component Definition

All Universal Agent components managed by Universal Broker have a component definition. The component definition is a text file of options containing component-specific information required by Universal Broker. (For details on how Universal Broker manages components, see the Universal Broker 7.3.x Reference Guide.)

The syntax of a component definition file is the same as a configuration file.

The UDM Server for UNIX component definition is located in the component definition directory of the Universal Broker.

Component Definition Options

The following table identifies all of the options that comprise the UDM Server for UNIX component definition. Each Option Name is a link to detailed information about that component definition option.

Option Name

Description

ALLOW_REPL_ON_RENAME

Specification for whether or not the UDM rename command will succeed if the new file name provided in that command matches the name of an existing file.

AUTOMATICALLY_START

Specification for whether or not UDM Server starts automatically when Universal Broker is started.

COMPONENT_NAME

Name by which the clients know the UDM Server.

CONFIGURATION_FILE

Full path name of the UDM Server configuration file.

RUNNING_MAXIMUM

Maximum number of UDM Servers that can run simultaneously.

START_COMMAND

Full path name of the UDM Server program.

WORKING_DIRECTORY

Full path name of the UDM Server working directory.

Configuration

Universal Data Mover Server configuration consists of defining runtime and default values. This section describes the UDM Server configuration options.

Configuration File

The configuration file provides the simplest method of specifying configuration values that will not change with each command invocation.

The Universal Data Mover Server configuration file name (and directory) is specified in the Universal Data Mover Server component definition (see Universal Data Mover Component Definition Options). The default configuration file name is udms.conf.

This file can be edited manually with any text editor.


Configuration Options

The following table identifies all UDM Server for UNIX configuration options. Each Option Name is a link to detailed information about that configuration option.

OUTBOUND_IP

Host or IP address that UDM binds to when initiating outgoing connections to another UDM server.

RECONNECT_RETRY_COUNT

Number of attempts that the UDM Manager will make to re-establish a transfer session when a network fault occurs.

RECONNECT_RETRY_INTERVAL

Number of seconds that UDM will wait between each successive attempt to re-establish a transfer session when a network fault occurs.

RECV_BUFFER_SIZE

Size (in bytes) of the application's incoming buffer for UDM.

SEND_BUFFER_SIZE

Size (in bytes) of the application's outgoing buffer for UDM.

TCP_NO_DELAY

Specification for whether or not to use TCP packet coalescing.

TCP_WINDOW_SIZE

Universal Access Control List

UDM Server uses the Universal Access Control List (UACL) file as an extra layer of security. The UACL file contains UDM Server entries that contain Access Control List (ACL) rules that permit or deny access to the UDM Server.

UACL Entries

The syntax of a UACL entry file is the same as the UDM configuration file.

The following table identifies all UDM Server for UNIX UACL entries. Each UACL Entry Name is a link to detailed information about that UACL entry.

UACL Entry Name

Description

UDM_ACCESS

Allows or denies access to Universal Data Mover Server services

UDM_MGR_ACCESS

Allows or denies access based on the host name and/or user of the Manager trying to initiate a UDM session
