Overview

This page provides information on the Universal Data Mover (UDM) Server, specific to the z/OS 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 7.6.x Reference Guide.)

The UDM Server for z/OS component definition is located in the component definition library #HLQ.UNV.UNVCOMP allocated to the Universal Broker ddname UNVCOMP. The UDM Server component definition member is UDSCMP00.

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

Option Name	Description
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	Member name of the UDM Server configuration file in the UNVCONF library allocated to the Broker ddname UNVCONF.
RUNNING_MAXIMUM	Maximum number of UDM Servers that can run simultaneously.
START_COMMAND	Member name of the UDM Server program.
WORKING_DIRECTORY	HMS directory used as the working directory of the UDM Server.

Configuration

Universal Data Mover Server configuration consists of defining runtime and default values.

Configuration File

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

The UDM Server configuration file name is specified in the Universal Data Mover Server component definition (see Universal Data Mover Component Definition Options). The default name is UDSCFG00. The name refers to a member in the PDS allocated to the Universal Broker ddname UNVCONF.

Configuration Options

The following table identifies all UDM Server for z/OS command options. Each Option Name is a link to detailed information about that option.

FRAME_INTERVAL	Number of UDM transfer blocks transferred before a frame-sync message is sent with network fault tolerance turned on.
MESSAGE_LEVEL	Level of messages that UDM will write to the Universal message Catalog (UMC) file.
MIN_SSL_PROTOCOL	Minimum SSL/TLS protocol level that will be negotiated and used for communications channels.
MSG_SUPPRESSION_LIST	List of message IDs representing Universal messages to be suppressed.
NETWORK_DELAY	Expected network latency (in seconds).
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.

UMASK	File mode creation mask.
USER_SECURITY	User security option.
VERIFY_HOST_NAME	User security option. Specification for whether or not the Universal Broker's X.509 certificate identity is verified.

Universal Access Control List

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