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

Overview

This page provides information on Universal Command (UCMD) Manager specific to the IBM i operating system.

UCMD Manager for IBM i provides an IBM i command interface to remote computers running the UCMD Server component. UCMD Manager executes remote commands as they would be if you entered the command directly on the remote command line.

On the command line, you must specify a command to execute and a remote Universal Broker. Additional input to each execution of the UCMD Manager command is made via configuration options, which control product behavior and resource allocation for that execution.

Remote standard input and output files are redirected to the UCMD Manager's standard input and output files.

Usage

UCMD Manager for IBM i executes as a CL command. This section describes the command environment, 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 UCHGRLS (Change Release Tag) program lets you change the tagged command names in QSYS to the untagged command names in UNVPRD511.

(See UCHGRLS (Change Release Tag) Program for detailed information on UCHGRLS.)

These pages references the IBM i commands by their untagged names. If you are using commands with tagged names to run UCMD, 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

Configuration

Configuration consists of:

Setting default options and preferences for all executions of UCMD Manager.
Setting options and preferences for a single execution of UCMD Manager.

UCMD Manager for IBM i configuration options are read from the following sources:

STRUCM parameters
Environment variables
Configuration file

The order of precedence is the same as the list above; STRUCM parameters being the highest, and configuration file being the lowest. That is, options specified via STRUCM parameters override options specified via environment variables, and so on.

For detailed information on these methods of configuration, see Configuration Management.

Configuration File

The configuration file, UNVPRD511/UNVCONF(UCMD), provides the simplest method of specifying configuration options whose values you do not want changed 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 UCMD Manager.

Configuration Options

This section describes the configuration options used to execute UCMD Manager for IBM i.

Configuration Options Categories

The following table categorizes the configuration options into logical areas of application. Each Category name is a link to a table of options in that category. Each Option Name in those tables is a link to detailed information about that option.

Category	Description
Certificates	X.509 certificate related options.
Command	Command or script to execute on the remote system. If a script is being executed, the script may reside on the local host on which the Manager is running or the remote host on which the Server is running. It also includes options to control the process environment in which the command executes.
Events	Options used to define event generation.
Local	Options required for local broker registration.
Messages	Universal Command message options.
Miscellaneous	Options use to display command help and program versions.
Network	Processing options for all the data transferred between the remote and local systems.
Options	Alternative methods to specify command options.
Remote	Network address of the remote system and connection options.
Standard File	Processing options for the standard files transferred between the remote and local systems. At the program interface level, the STDFILE options are specified differently then the other options. There are three types of standard files: stdin, stdout, and stderr. Each standard file can have a different set of options applied. In order to distinguish between the standard files, the options must start with a standard file specification option (STDERR_FILE_SPEC, STDIN_FILE_SPEC, or STDOUT_FILE_SPEC). The standard file options (see #Standard File Category Options) follow the standard file specification option. The STRUCM command interface hides this difference from the user.
User	User account the command executes with on the remote system.

CA_CERTIFICATES	Location of the PEM formatted trusted CA X.509 certificates
CERTIFICATE	Location of Manager's PEM formatted X.509 certificate.

* The command file (CMDFILE or ECMFILE) can contain some or all required and/or optional configuration options, including CMD (or SCRFILE) and HOST. If a command file is specified on the command line, and it contains the required CMD (or SCRFILE) and HOST options, those options do not have to be specified additionally on the command line.
