Universal Data Mover Server for IBM i
Currently, IBM i runs Workload Automation 5.1.1. These pages provide information for that version.
Overview
This page provides the following information on the Universal Data Mover (UDM) Server, specific to the IBM i operating system.
Component Definition
All Workload Automation 5 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 IBM i 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 IBM i component definition. Each Option Name is a link to detailed information about that component definition option.
Option Name | Description |
|---|---|
Specification for whether or not UDM Server starts automatically when Universal Broker is started. | |
Name by which the clients know the UDM Server. | |
Full path name of the UDM Server configuration file. | |
Maximum number of UDM Servers that can run simultaneously. | |
Full path name of the UDM Server program. | |
Full path name of the UDM Server working directory. |
Configuration
UDM Server configuration consists of defining runtime and default values. This section describes the 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 UDM Server configuration file name is specified in the UDM Server component definition (see Universal Data Mover Component Definition Options). The default name is UNVPRD511/UNVCONF(UDMS).
This file can be edited manually with any text editor.
Configuration Options
The following table identifies all Universal Data Mover Server for IBM i configuration options. Each Option Name is a link to detailed information about that configuration option.
Option | Description |
Specification for whether or not product activity monitoring events are generated. | |
Character code page used to translate text data. | |
Specification to use either the internal or external table for code page to CCSID mapping. | |
Specification for whether or not data is compressed on all standard I/O files. | |
SSL/TLS cipher suites to use for data session between UDM primary and secondary servers. | |
Events to be generated as persistent events. | |
Number of UDM transfer blocks transferred before a frame-sync message is sent with network fault tolerance turned on. | |
Level of messages that UDM will write to the Universal message Catalog (UMC) file. | |
Minimum SSL/TLS protocol level that will be negotiated and used for communications channels. Note This option was introduced to IBM i in version 5.1.1.0. | |
Expected network latency (in seconds). | |
Host or IP address that UDM binds to when initiating outgoing connections to another UDM server. | |
Number of attempts that the UDM Manager will make to re-establish a transfer session when a network fault occurs. | |
Number of seconds that UDM will wait between each successive attempt to re-establish a transfer session when a network fault occurs. | |
Size (in bytes) of the application's incoming buffer for UDM. | |
Size (in bytes) of the application's outgoing buffer for UDM. | |
Default size for file creation of physical files for both data and source file types. | |
Specification for whether or not to use TCP packet coalescing. | |
TCP/IP buffer size of a secondary UDM Server that receives a file from a primary Server in a three-party transfer. | |
Directory that UDM Server uses for temporary files. | |
Maximum number of lines to write to the trace file. | |
Size of a wrap-around trace table maintained in memory. | |
File mode creation mask. | |
User security option. |
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 IBM i UACL entries. Each UACL Entry Name is a link to detailed information about that UACL entry.
UACL Entry Name | Description |
|---|---|
Allows or denies access to Universal Data Mover Server services | |
Allows or denies access based on the host name and/or user of the Manager trying to initiate a UDM session |
