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-7.6.x.x-aix-7.1-ppc64.tar.Z | tar xvf -

This command assumes the following:

Name of the distribution file is sb-7.6.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.

File	Description
Readme.unv	Summary of the installation procedure.
unv-7.6.x.x-aix-7.1-ppc64.rpm	AIX RPM file format package.
unv-opscli-7.6.x.x-aix-7.1-ppc64.rpm	Universal Controller Command Line Interface (CLI) RPM file format package.
unvinst	Installation script.
upimerge.sh	Script that uses the Universal Installation Merge (UIM) module.
usrmode.inc	User-mode installer main script.
unvfiles.tar	User-mode installer modules archive; a set of scripts loaded and executed by usrmode.inc.
unv-python3.11.tar	Python 3.11 Distribution for Universal Agent.

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. UAG is activated using the --oms_servers parameter.
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. OMS is activated using the --oms_autostart parameter.
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. Universal Controller command line programs are installed using the --opscli parameter.
Third-party components	Not installed.	This category includes components not developed or maintained by Stonebranch, Inc. For example, Universal Agent 7.6.0.0 provides a Python 3.11 distribution that can be installed under the Universal Agent install directory. This distribution is provided so that a reliable Python environment exists on systems that may not provide for all users.

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-7.6.0/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.

AIX Installation Script Parameters

The following table describes the optional parameters that are available in the installation script, unvinst, when installing Universal Agent.

The parameters are grouped into the following categories:

Category	Description
Base	Used for base install.
OMS	Used for an active OMS configuration.
UAG	Used for an active UAG configuration.
CLI	Used for Universal Controller CLI programs install.
User Mode	Used for user mode installation.
Third-party	Used to manage third-party components.

Parameter	Description	Default
Base Parameters
-u ‑user --user	Normal UNIX username that is used to execute the Universal Broker daemon. The install grants this user account ownership of all installed files, with the exception of the Universal Agent server components (for example: ucmsrv, udmsrv, and uemsrv) which, due to security requirements, are owned by root and will have their "set user ID on execution" bit set. If the user account that you want to use already exists, specify that user account. If the user account does not exist, the install creates it. If you want to change the user account for an installed Universal Agent for AIX system, you must perform a re-installation and use this parameter to change the user account. If --user is omitted from `unvinst`, the default is used. If --usermode_install is yes, there is no default.	ubroker
‑create_user ‑‑create_user	Specification (yes or no) for whether or not to create the user name that will own the installed files as a local user.	yes
‑userdir ‑‑userdir	Home directory for the created user account specified by --user. If this directory does not exist, it is created when the specified user is created. If the user specified by --user already exists, but the home directory of that user is not the default directory (`/home/<username>`), `--userdir` must specify the path to that home directory. If --userdir is omitted from `unvinst`, the default is used.	`/home/<username>`
-g ‑group ‑‑group	Normal UNIX groupname; the Universal Broker daemon will run as this specified group. All installed files will be assigned to this group. If the group that you want to use already exists, specify that group. If this group does not exist, the install creates it. If --group is omitted from `unvinst`, the default is used.	ubroker
‑create_group ‑‑create_group	Specification (yes or no) for whether or not to create the group that will own the installed files as a local group.	yes
‑keystore ‑‑keystore	Specification (yes or no) for whether or not to create encryption keys during installation and set up the local Universal Broker as a keystore owner.	no
‑use_tls1_3 ‑‑use_tls1_3	If specified (using yes), all components will be set up to use TLS 1.3 by setting the `max_ssl_protocol` option to `tls1_3` (and `encrypt` to `yes` for UCMD and UDM).	no
UAG Parameters
-c ‑convert ‑‑convert_opsagent	Converts an existing Opswise Automation Center Agent (1.5, 1.6, or 1.7) to a 5.2.0 Agent. The installation process will invoke a script, `opsmerge.sh`, which stops the Agent and converts the configuration options stored in its `agent.props` file to corresponding configuration options in the Universal Automation Center Agent (UAG) `uags.conf` file. The script also performs several other tasks needed for the conversion. Note You must include this parameter when upgrading an Opswise Automation Center Agent (1.5, 1.6, or 1.7) to Universal Agent 7.6.x.x.
-d ‑opsdir ‑‑opsdir	If --convert_opsagent is specified: Identifies the primary install directory for Universal Agent. If --opsdir is omitted from `unvinst`, the default is used.	`/home/opswise`
‑oms_servers ‑‑oms_servers	Specifies a value, in the format `port@host[,port2@host,...,portn@hostn]`, for the port and network address of the OMS server(s) to be used as network communications providers. Note You should always include --oms_servers in `unvinst`; OMS is the network communications provider between Controller 7.6.x.x and Agent 7.6.x.x. UAG configuration: The value specified for --oms_servers is set automatically for the UAG OMS_SERVERS configuration option.	(none)
‑ac_agent_clusters ‑‑ac_agent_clusters	Specifies the Universal Controller-defined clusters to which this agent will belong. UAG configuration: The value specified by --ac_agent_clusters is set automatically for the UAG AGENT_CLUSTERS configuration option.	(none)
‑ac_agent_ip ‑‑ac_agent_ip	Specifies the IP address or host name (which resolves to an IP address) that the Agent reports to the Controller. UAG configuration: The value specified by --ac_agent_ip is set automatically for the UAG AGENT_IP configuration option.	(none)
‑ac_netname ‑‑ac_netname	Specifies the network ID that Universal Agent will use. UAG configuration: The value specified by --ac_netname is set automatically for the UAG NETNAME configuration option.	(none)
-ac_extension_accept_list --ac_extension_accept_list	Specifies a comma-separated list of one or more Universal Extensions that the agent will accept via auto-deployment from the Controller. A single value of * indicates that all extensions are accepted. A single value of none indicates that no extensions are accepted. The value specified for this parameter sets the EXTENSION_ACCEPT_LIST configuration option value.	*
-ac_extension_python_list --ac_extension_python_list	Specifies a comma-separated list of zero or more Python locations. Each item in the list is expected to contain a complete path to a Python executable. The value specified for this parameter sets the EXTENSION_PYTHON_LIST configuration option value.	/usr/bin/python3,/usr/bin/python,/usr/libexec/platform-python
-ac_extension_deploy_on_registration --ac_extension_deploy_on_registration	Controls Extension deployment behavior from the Universal Controller. If the value is yes, the Controller will preemptively deploy all extensions acceptable by UAG. If the value is no, the Controller will only send Extension modules as needed (on demand). The value specified for this parameter sets the EXTENSION_DEPLOY_ON_REGISTRATION configuration option value.	no
-ac_extension_cancel_timeout --ac_extension_cancel_timeout	Set the EXTENSION_CANCEL_TIMEOUT UAG configuration option, which specifies the length of time a Universal Extension task is given to complete its response to a CANCEL request. If the task fails to finish its own termination processing within the specified timeout period, UAG Server will forcefully terminate the task. The specified timeout must be numeric, but a one-letter suffix is accepted to specify (s)econds, (m)inutes, (h)ours, or (d)ays. If no time unit is specified, the default is seconds. The following maximums are enforced: 2147483647 or 2147483647s 35791394m 596523h 24855d Minute, hour, and day maximums are set to ensure that their value represented as a number of seconds does not exceed 2147483647.	10
‑ac_enable_ssl ‑‑ac_enable_ssl	This option is deprecated starting with Universal Agent 7.1.0.0. UAG Server will always attempt to use SSL/TLS for OMS connections.	no
-ac_process_cancel_timeout --ac_process_cancel_timeout	Set the PROCESS_CANCEL_TIMEOUT UAG configuration option, which specifies the length of time an OS task is given to complete its response to a CANCEL request. If the task fails to finish its own termination processing within the specified timeout period, UAG Server will forcefully terminate the task. The specified timeout must be numeric, but a one-letter suffix is accepted to specify (s)econds, (m)inutes, (h)ours, or (d)ays. If no time unit is specified, the default is seconds. The following maximums are enforced: 2147483647 or 2147483647s 35791394m 596523h 24855d Minute, hour, and day maximums are set to ensure that their value represented as a number of seconds does not exceed 2147483647.	10

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
--usermode_install	yes
--user	A username that is different than the username specified for any other Agent installation on this machine.
--unvdir	An Agent binaries (installation) directory that is different than the installation directory specified for any other Agent installation on this machine.
--unvport	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
--unvdir	/opt/universal	Agent binaries
--unvcfgdir	/etc/universal	Agent configuration files
--unvdatadir	/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

Removing Universal Agent for AIX

System Install Removal

Step 1	Stop the ubrokerd daemon.
Step 2	Make a backup copy of the `/etc/universal` and `/var/opt/universal` directories.
Step 3	Using the superuser ID, remove all Universal Agent for AIX packages by issuing the following commands: rpm -e unv-opscli rpm -e unv rm -rf /etc/universal rm -rf /var/opt/universal
Step 4	Delete the Agent user account (`ubroker`) and its home directory: rmuser ubroker
Step 5	Delete the Agent group (`ubroker`): rmgroup ubroker

User Mode Install Removal

Step 1	Stop the Usermode Broker.
Step 2	Make a backup copy of the `<--unvcfgdir>` and `<--unvdatadir>` directories.
Step 3	Using the superuser ID, remove all Universal Agent for Linux packages by issuing the following commands: rm -rf <---unvdir> rm -rf <--unvcfgdir> rm -rf <--unvdatadir>
Step 4	Delete the Agent user account (`ubroker`) and its home directory: userdel -r [Usermode Broker user]
Step 5	Delete the Agent group (`ubroker`): rmgroup [Usermode Broker group]

Agent

To remove an Agent executing in an unprivileged user mode environment (see User Mode Installation), simply stop the ubrokerd daemon and remove the ./universal installation directory. To make sure that you do not mistakenly remove a system install directory, attempt the removal with a non-privileged user account or the Broker account.
