Currently, IBM i runs Workload Automation 5.1.1. These pages provide information for that version.

Configuration

Universal Broker reads configuration options only from the Universal Broker configuration file.

The Universal Broker configuration file is named UNVPRD511/UNVCONF(UBROKER). File UNVCONF is a physical source file located in the UNVPRD511 library. File member UBROKER contains the configuration options for the Universal Broker. File UNVCONF contains configuration members for the Workload Automation 5 for IBM i components. This file can be edited manually with any text editor.

Component Management

Universal Broker is aware only of Universal Agent components that have been defined. It is the responsibility of Universal Broker to start, stop, and query these defined components.

One of the steps in the installation of a component is defining it to the local Universal Broker. These component definitions provide Universal Broker with the necessary information that it needs to manage the components.

Component Definitions

Component definitions are text files that define Universal Agent components to the Universal Broker. All IBM i component definitions are located in the source physical file UNVPRD511/UNVCOMP as individual members.

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

The following table identifies all of the options that comprise Universal Agent for IBM i component definitions. Each Option Name is a link to detailed information about that option.

Option Name	Description
AUTOMATICALLY_START	Specification for whether or not the component automatically starts by the Universal Broker at start-up time or only on demand.
COMPONENT_NAME	Name by which clients know the component.
COMPONENT_TYPE	Type of component.
CONFIGURATION_FILE *	Component's configuration file name.
RESTART	Specification for whether or not the component should be restarted if it ends.
RESTART_CONDITIONS	Exit conditions criteria for which the server is considered eligible for restart.
RESTART_DELAY	Number of seconds to wait before restarting.
RESTART_MAX_FREQUENCY	Maximum frequency a server can be restarted.
RUNNING_MAXIMUM	Maximum number of this component that can run simultaneously.
START_COMMAND *	Component program name.
WORKING_DIRECTORY *	Path used as the working directory of the component.
* These options are required in the component definitions.

Universal Access Control List

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

Universal Broker reads in the UACL entries when the program is started. If the UACL file is changed, the new entries can be activated either by:

Stopping and starting Universal Broker.
Sending Universal Broker a Universal Control REFRESH command, which instructs Universal Broker to reread all its configuration files, including the UACL file.

The IBM i REFRESH command is:

STRUCT REFRESH(*YES) HOST(hostname)

UACL Entries

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

The following table identifies all Universal Broker for IBM i UACL entries. Each UACL Entry Name is a link to detailed information about that option.

UACL Entry Name	Description
UBROKER_ACCESS	Allows or denies access to Universal Broker services.
CERT_MAP	Maps a client X.509 certificate to a certificate identifier.
EVENT_ACCESS	Controls which Universal Enterprise Controller has read and delete access to the Universal Event Subsystem event data maintained by the Universal Broker.
REMOTE_CONFIG_ACCESS	Authorizes update access to the product configuration files and setting of the configuration managed mode of the Universal Broker.
