Universal Agent for AIX Installation
Installation Process
Installation of Universal Agent for AIX is a three-step process:
Step 1 | Download the product distribution file. |
---|---|
Step 2 | Extract the installation files from the distribution file. |
Step 3 | Install the extracted files. |
Extracting the Universal Agent for AIX Installation Files
The Universal Agent for AIX product distribution file is in a compressed tar format.
To uncompress and extract the installation files from the distribution file, issue the following command:
zcat sb-7.7.x.x-aix-7.1-ppc64.tar.Z | tar xvf -
This command assumes the following:
- Name of the distribution file is
sb-7.7.x.x-aix-7.1-ppc64.tar.Z
. - File is located in the current working directory.
Distribution File
The distribution file contains multiple files, including packages in the AIX backup file format, using extension .bff. The actual base name of the .bff file depends on the AIX version for which the distribution file is intended. (See Distribution File Format for distribution file naming conventions.)
The following table identifies the files contained in the distribution file.

Note
If your Universal Agent for AIX distribution file does not contain all of these files, contact Stonebranch, Inc. Customer Support to obtain a correct distribution file.
Installing Universal Agent for AIX
Universal Agent for AIX is installed with the unvinst
script, which executes the rpm command. The command to start the script must be executed with the superuser ID.
Note
Stonebranch, Inc. strongly recommends the use of the unvinst
script for the AIX installation above any other method.
Component Selection
The Universal Agent package contains many components, which are grouped into five categories. Components in some categories are installed and activated optionally, as specified in the unvinst
script by using unvinst
command line parameters.
The following table describes each category, provides the default installation configuration for the components in that category, and identifies the command line parameters to use for components that are optionally installed and activated.
Note
The default installation configuration refers to new installs only. For upgrades, installed component configurations are not changed by the upgrade process.
Category | Default Configuration | Description |
---|---|---|
Base components | Always installed. | Base components are always installed and activated. They include the Universal Broker, Universal Command (UCM), Universal Data Mover (UDM), and others. Base components provide the core agent infrastructure and workload services. |
Universal Automation Center Agent (UAG) | Always installed, but inactive. | Universal Controller utilizes UAG agents to provided distributed, workload automation services. |
Universal Message Service (OMS) | Always installed, but inactive. | OMS is message-oriented middleware that should be deployed on a small set of centrally located servers. It should not be activated on every Agent install. OMS is the network provider for UAG and the Universal Controller. |
Universal Controller command line programs | Not installed. | Universal Controller command line programs provide a command line interface to the Universal Controller. The installation of Universal Controller command line programs is optional. The command line programs are only required on Agents that need to interface with the Universal Controller via the command line. |
Third-party components | Not installed. | This category includes components not developed or maintained by Stonebranch, Inc. |
Starting the Installation Script
To start the unvinst
installation script and install all of the AIX packages, issue the following command:
sh ./unvinst [--user username [--userdir directory] [--create_user {yes|no}] ] [--group group name [--create_group {yes|no}] ] [--keystore {yes|no}] [--convert_opsagent [--opsdir directory] ] [--oms_servers network address] [--oms_port port] [--ac_agent_clusters clusters] [--ac_agent_ip IP address] [--oms_autostart {yes|no}] [--ac_netname ID] [--ac_extension_accept_list list] [--ac_extension_python_list list] [--ac_extension_deploy_on_registration {yes|no}] [--ac_extension_cancel_timeout value {s|m|h|d}] [--ac_process_cancel_timeout value {s|m|h|d}] [--ac_message_level level] [--ac_loglvl level] [--uag_autostart yes] [--opscli {yes|no}] [--usermode_install {yes|no} [--unvdir directory] [--unvcfgdir directory] [--unvdatadir directory] [--unvport port] [--python {yes|no}] [--use_tls1_3 {yes|no}]
See AIX Installation Script Parameters and Installation Script Example, below, for a description of the optional parameters that you can issue with unvinst
and an example of unvinst
with these parameters.
Note
If you want to install multiple Agents on the same machine, or add one or more additional Agents to a machine with a previously installed Agent, some of these installation parameters are required (see Installing Multiple Agents on a Single Machine).
This is a silent install. The output from unvinst
is written to file install.log in the current directory.
An entry is added to the system initialization table, /etc/inittab, to start the ubrokerd daemon when the system boots to runlevel 2. The inittab entry is similar to the following:
ubroker:2:once:/opt/universal/ubroker-7.7.0/ubrokerd start
The Universal Broker daemon will be installed and run as the username and groupname specified with the installation script parameters, below.
Note
With the Solaris, HP, and AIX installs, the previous installation directories are removed when the native installer has detected that additional directories or files have not been added to the original installation directories. If they have been modified, the directories will remain and can be reviewed and removed, as desired, by your Administrator.

Installation Script Example
The following example illustrates Universal Agent for AIX installed with the installation script, unvinst
, and optional parameters.
sh ./unvinst --user user1 --userdir /homedir/user --group usergroup --keystore no --convert_opsagent --opsdir /homedir/ops --oms_servers 7878@oms2 --oms_port 7878 --oms_autostart yes --ac_agent_clusters GA Cluster,CA Cluster --ac_agent_ip 127.0.0.1 --ac_netname OPSAUTOCONF --opscli yes --uag_autostart yes --usermode_install yes --unvdir /opt/universal --unvcfgdir /etc/universal --unvdatadir /var/opt/universal --unvport 7887
User Mode Installation
A user mode installation, implemented through use of the usermode_install installation parameter, lets you install multiple Agents on a single machine and change the default installation directories for any Agent being installed.
You must perform a user mode installation for installing an Agent on a machine where one or more Agents already have been installed.
However, you also can perform a user mode installation for the initial installation of an Agent on a machine.
Note
You can execute the install as a non-root user if you want to execute the Agent in an unprivileged user mode environment. See User Mode Installation for specific requirements and restrictions associated with an unprivileged user mode environment.
Installing Multiple Agents on a Single Machine
If you want to install multiple Agents on the same machine, you must set the following installation parameter values for each Agent being installed in addition to the initially installed Agent.
Note
You also can set these parameters values for the initial installation of an Agent on a machine.
Installation Parameter | Value |
---|---|
yes | |
A username that is different than the username specified for any other Agent installation on this machine. | |
An Agent binaries (installation) directory that is different than the installation directory specified for any other Agent installation on this machine. | |
A Universal Broker port that is different than the port specified for any other Agent installation on this machine. |
Changing the Default Installation Directories
By default, an Agent is installed and configured in default directories.
If you want to change these default directories, or if you want to install multiple Agents on the same machine, you must set the --usermode_install parameter to yes and specify new values in the following parameters. These directories must be different for each Agent on the same machine.
Note
You also can change these directories for the initial installation of an Agent on a machine.
Installation Parameter | Default Directory | Files Installed |
---|---|---|
/opt/universal | Agent binaries | |
/etc/universal | Agent configuration files | |
/var/opt/universal | Agent data files |
AIX PAM Customization
If security is set to PAM, the pam.conf file under /etc must be modified.
Below is the minimum required PAM service definition to make Universal Agent function:
ucmd | auth | required | /usr/lib/security/pam_aix |
ucmd | account | required | /usr/lib/security/pam_aix |
Listing Universal Agent for AIX Information
Information on installed packages is listed with the rpm command. The command must be executed with the superuser ID.
To list information for the Universal Agent for AIX, issue the following command:
rpm -qi unv rpm -qi unv-opscli
