In Oracle Solaris 11

To help system administrators get up to speed quickly using the Image Packaging System (IPS) in Oracle Solaris 11, we collected a summary of commonly used IPS commands in the "Oracle Solaris 11 Cheat Sheet for the Image Packaging System." This article expands on that cheat sheet by reviewing basic IPS concepts and showing you how to perform basic operations with those commands.
IPS is a new model for software packaging introduced in Oracle Solaris 11. It is a comprehensive delivery framework that spans the full software lifecycle, addressing software installation, system updates, upgrades, and software package removal. In contrast to the SVR4 packaging model in earlier Oracle Solaris releases, IPS radically changes how you perform software maintenance because it eliminates OS patching. Instead, IPS relies on the use of network-centric software repositories for software updates as well as for installation.
IPS pulls software packages from locally connected or remote software package repositories, automatically checking for software dependencies and installing the required software. Since IPS checks software versions in non-global zones for consistency with the global zone, it also aids in administering the software configuration for zones in a system.
Although IPS does not always generate an Oracle Solaris 11 boot environment (BE) when you add or update software, it is generally good administrative practice to do so. Since creating a new BE takes advantage of built-in ZFS snapshot capabilities, you can build a system clone almost instantly without requiring additional space. Creating a BE allows you to perform the update even if the system is a live production system. You can then activate the updated BE at the next reboot, and if there's a problem, you can roll back to the previous software state. In this way, IPS facilitates safe and controlled transitions between software configurations.
For more technical information about IPS, go to the Oracle Solaris 11 Lifecycle Management Technology Page.
Figure 1. Oracle Solaris IPS can apply updates to a clone of the current boot environment.
The primary administrative interface for IPS is the
pkg command. Many of its subcommands query the current software state (for example, the
history subcommands) and can be performed by any user. Only privileged administrators, however, can perform subcommands that change the system software image (such as
pkg uninstall, or
Table 1 lists a few examples of Oracle Solaris 11 pkg commands and their SVR4 equivalents.Table 1. Example of
|Task||IPS command||SVR4 Packaging Command|
|Update installed package(s) in current image||
|Display package state and version information||
|Verify package installation||
|Display package information, such as license||
|Display contents of a package||
|Search for a package||
In the following example, the
pkg install command installs the
diagnostic/wireshark package, along with dependencies if any exist:
# pkg install diagnostic/wireshark
pkg update command updates installed packages to the newest versions, including packages that are installed in Oracle Solaris 11 zones. To preview its actions, use the
-nv argument, for example:
# pkg update -nv
To create a new boot environment for an update called
be_fix-nfs, enter this command:
# pkg update --be-name be_fix-nfs
pkg contents, and
pkg search commands are typically the tools you use to investigate and learn more about installed and uninstalled packages. For example, on an Oracle Solaris 11 system, the
pkg list command lists what's currently installed:
$ pkg list
To display information about a specific installed package called
wireshark, enter this command:
$ pkg info wireshark
To search currently configured software repositories for information about an uninstalled package called
xchat, use the
-r argument to
$ pkg info -r xchat
To display the contents of the
wireshark package, enter this command:
$ pkg contents wireshark
To display all locally installed packages that match the string
gcc, enter the following:
$ pkg search -l gcc
To list all packages in the configured software repositories containing header file
gcrypt-module.h, enter this command:
$ pkg search 'gcrypt-module.h'
To find all packages installed locally that have a dependency on
library/libxml2, enter the following:
$ pkg search --l -o pkg.name 'depend::library/libxml2'
Some of the
pkg subcommands display information about a software package in the format of a Fault Managed Resource Indicator (FMRI). An FMRI uniquely describes a software package, including the package's publisher and specific identification details, as in this sample output from
$ pkg info wireshark pkg://email@example.com,5.11-0.175.3.33.0.5.0:20180530T182122Z
In this FMRI,
solaris is the publisher,
diagnostic/wireshark is the package name,
2.6.1 is the component version,
5.11 is the build version,
0.175.3.33.0.5.0 is the branch version, and
20180530T182122Z is the package time stamp. For more information about FMRI identifiers, see the
pkg(1) man page.
Software developers, including Oracle, publish their software in software package repositories. Administrators access these repositories to install new systems, add or update software packages, or search for package information. In addition, administrators can make a local copy of repositories if systems reside in a network-restricted environment (refer back to Figure 1).
You can use the
pkg publisher command to show the currently configured repositories:
# pkg publisher PUBLISHER TYPE STATUS URI solaris origin online http://pkg.oracle.com/solaris/release/
Oracle Solaris 11 has a default publisher,
solaris, which supplies software packages from the release repository http://pkg.oracle.com/solaris/release/. Customers who have an active Oracle support agreement can change the default publisher to point to the Oracle Solaris 11 support repository at https://pkg.oracle.com/solaris/support:
# pkg set-publisher -G http://pkg.oracle.com/solaris11/release \ -g http://pkg.oracle.com/solaris11/support -k /path/to/ssl_key \ -c /path/to/ssl_cert solaris # pkg publisher PUBLISHER TYPE STATUS URI solaris origin online https://pkg.oracle.com/solaris/support/
In the Oracle Technology Network article "How to Update Oracle Solaris 11 Systems From Oracle Support Repositories," Glynn Foster steps through the process of downloading security certificates and keys and switching to the support repository.
If you choose to set up a local repository copy, you need to add a new publisher at the URI, for example:
# pkg set-publisher -p http://www.example.com/solaris11
The system records a history of package installations, updates, and modifications in a log file. To browse the
pkg command history (including actions performed using the graphical Package Manager client), use the
pkg history command. The
-n option displays the specified number of the most recent operations:
# pkg history -n4 START OPERATION CLIENT OUTCOME 2018-07-19T05:45:48 fix pkg Succeeded 2018-07-23T22:00:22 refresh-publishers pkg Succeeded 2018-07-23T22:00:47 rebuild-image-catalogs pkg Succeeded 2018-07-23T22:22:42 update pkg Succeeded
To purge the
pkg command history (which basically empties the log file), enter this:
# pkg purge-history
To verify the integrity of the current system image, enter the following:
# pkg verify
To verify the integrity of an installed package, enter a
pkg verify command with the package name:
# pkg verify -v system/install/auto-install/auto-install-common PACKAGE STATUS pkg://solaris/system/install/auto-install/auto-install-common ERROR file: usr/share/auto_install/manifest/default.xml ERROR: Missing: regular file does not exist
pkg verify command validates package signatures, depending on the signature policy.
To fix errors reported by
pkg verify on an installed package, use
pkg fix with the
--accept option to indicate that you accept the license terms for the specified packages, as shown in Listing 1.
# pkg fix --accept system/install/auto-install/auto-install-common Packages to fix: 1 Create boot environment: No Create backup boot environment: Yes Repairing: pkg://firstname.lastname@example.org,5.11-0.175.3.30.0.4.0:20180305T200507Z PACKAGE STATUS pkg://solaris/system/install/auto-install/auto-install-common ERROR file: usr/share/auto_install/manifest/default.xml ERROR: Missing: regular file does not exist DOWNLOAD PKGS FILES XFER (MB) SPEED Completed 1/1 1/1 0.0/0.0 2.5k/s PHASE ITEMS Updating modified actions 1/1 Updating package state database Done Updating package cache 0/0 Updating image state Done Creating fast lookup database Done Updating package cache 1/1

To prevent future updates and freeze a package's state, enter the following command:
# pkg freeze wireshark
You may want to freeze a package in a non-global zone if you do not want that package to be updated when the global zone is updated. To reverse this action and allow future updates, enter this:
# pkg unfreeze wireshark
