Universal Control Manager for IBM i
- Stonebranch (Deactivated)
Currently, IBM i runs Workload Automation 5.1.1. This page provides information for that version.
Introduction
This Universal Control (UCTL) Manager information is specific to the IBM i operating system.
Universal Control Manager for IBM i runs via a command interface. It provides a command line interface to remote computers running the UCTL Server. On the command line, you must specify the control request that you want the UCTL Manager to execute.
This page describes the the Universal Control Manager for IBM i command execution environments, control requests, configuration and configuration options, and command line syntax.
Workload Automation 5 for IBM i Commands
The names of the Workload Automation 5 for IBM i commands that are installed in the IBM i QSYS library are tagged with the Workload Automation 5 for IBM i version / release / modification number, 511. The names of the commands installed in the Workload Automation 5 for IBM i product library, UNVPRD511, are untagged.
To maintain consistency across releases, you may prefer to use the untagged names in your production environment. The Change Release Tag program, UCHGRLS, lets you change the tagged command names in QSYS to the untagged command names in UNVPRD511.
These pages reference the IBM i commands by their untagged names. If you are using commands with tagged names to run Universal Control, substitute the tagged names for the untagged names in these references.
Command Execution Environment
The command is valid in all environments:
- Batch input streams
- CL programs
- REXX procedures
- CL ILE modules
- Interactive processing
- Passed to the system program QCMDEXC (or QCAEXEC) for processing
Control Requests
UCTL Manager for IBM i supports all three Universal Control control requests:
- Start (START_CMD option)
- Stop (STOP_CMD option)
- Refresh (REFRESH_CMD option)
Configuration
Configuration consists of:
- Setting default options and preferences for all executions of UCTL Manager.
- Setting options and preferences for a single execution of UCTL Manager.
Configuration Sources
UCTL Manager for IBM i configuration options are read from the following sources:
- STRUCT parameters
- Environment variables
- Configuration file
The order of precedence is the same as the list above; STRUCT parameters being the highest, and configuration file being the lowest. That is, options specified via STRUCT parameters override options specified via environment variables, and so on.
Detailed information on these methods of configuration can be found in Configuration Management.
Configuration File
The configuration file, UNVPRD511/UNVCONF(UCTL), provides the simplest method of specifying configuration options whose values will not change with each command invocation. These default values are used if the options are not read from one or more other sources.
Some options only can be specified in the configuration file; they have no corresponding command line equivalent. Other options cannot be specified in the configuration file; they must be specified via one or more other sources for a single execution of UCTL Manager.

STRUCTVERSION(*{yes|no})
* The command file (CMDFILE or ECMFILE) can contain some or all required and/or optional configuration options, including a control request and HOST. If a command file is specified on the command line, and it contains the required control request and HOST options, those options do not have to be specified additionally on the command line.
