Managing Software With the Solaris Product Registry Command-Line Interface

The prodreg command is the command-line interface (CLI) to the Solaris Product Registry. The prodreg command supports several subcommands that enable you to manage the software on your system.

You can use the prodreg command in a terminal window to perform the following tasks:

View a list of installed and registered software and software attributes.
View all Solaris system products that you installed in their localized version in the System Software Localizations directory.
Identify damaged software.
Remove software entries from the Solaris Product Registry.
Uninstall software and individual software packages.

For more information on how to manage the Solaris Product Registry by using the command-line interface, see the prodreg(1M) man page.

How to View Installed or Uninstalled Software Information (`prodreg`)

You can view information about software in the Solaris Product Registry in a terminal window by using the browse subcommand to the prodreg command.

Open a terminal window.
Browse the Solaris Product Registry.
```
% prodreg browse
    BROWSE # +/-/.  UUID                                  #  NAME
    ======== =====  ====================================  =  ============

```
The browse subcommand to the prodreg command displays the following information about registered software.
BROWSE #

When you use the prodreg browse command, the Solaris Product Registry generates a browse number for each registered software component. This number can be used as an argument to either the prodreg browse command or the info subcommand to descend the hierarchy of specific registered components.

Note - Browse numbers might change when you reboot or reinstall your system. Do not store browse numbers in scripts or attempt to reuse them between separate login sessions.

+/-/.
This field indicates if a software component has additional software component children registered in the Solaris Product Registry.
The following characters are displayed in this field:
- + indicates that the software component has additional children components that are not currently displayed.
- - indicates that the software component has additional children components that are currently displayed.
- . indicates that the software component does not have children components.
UUID

This field lists the software's unique identifier in the Solaris Product Registry.

#

This field indicates the instance number of the software component on the system. If the system contains multiple instances of a software component, the Solaris Product Registry assigns a separate instance number to each instance of the component.

NAME

This field lists the localized name of the software. The name of the Solaris OS in this sample output is the Solaris 10 system software.
Browse the information for one of the software components that are listed in the Solaris Product Registry.
```
% prodreg browse -m "name"
```
The -m “name” command displays information on the software component with the name name.
If the system contains multiple instances of name software, type the following command to browse the Solaris Product Registry:
```
% prodreg browse -u name-UUID -i instance -n number
```
-u name-UUID

Displays information on the name software component with the unique identifier name-UUID.

-i instance

Displays information on the name software component with the instance number instance.

-n number

Displays software information by referencing the component's browse number number.
Repeat Step 3 and Step 4 for each software component that you want to browse.

The ExampleSoft child component EXSOzzt does not have an entry in the NAME field. The ExampleSoft software might be damaged. You would use the prodreg info command with the -u, -i, and -d options to determine if the ExampleSoft software is damaged.

% prodreg info -u 95842091-725a-8501-ef29-0472985982be -i 1 -d 
isDamaged=TRUE

The output isDamaged=TRUE indicates that the ExampleSoft software is damaged. You would use the -a PKGS option of the prodreg info command to identify the ExampleSoft software packages.

% prodreg info -u 95842091-725a-8501-ef29-0472985982be -i 1 -a PKGS 
pkgs: 
EXSOzzt EXSOblob

To verify that the EXSOzzt and EXSOblob packages are installed on the system, you would use the pkginfo command.

% pkginfo EXSOzzt 
ERROR: information for "EXSOzzt" was not found 

% pkginfo EXSOblob
application EXSOblob       Example Data

The output of the pkginfo command indicates that the EXSOzzt package is not installed on the system. Thus, the ExampleSoft software is damaged.

How to Uninstall Software (`prodreg`)

You can use the uninstall subcommand of the prodreg command to remove software from your system. When you uninstall software by using the prodreg uninstall command, you remove a specified software and all the child components associated with that software. Before you remove software, verify that other software does not depend on the software you want to uninstall. See How to Check for Software Dependencies (prodreg).

After you uninstall software, you can remove that software and all the child components of that software from the Solaris Product Registry by using the prodreg unregister -r command.

Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

How to Reinstall Damaged Software Components (`prodreg`)

If other software depends on a damaged software component, you might want to reinstall the damaged component, rather than uninstall the component and the other dependent software. You can use the -f option with the prodreg unregister command to forcibly the unregister the damaged component. Then, you can reinstall the component.

Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
