* Updating all of the packages on your installed systemTo update all of the packages on your system that have available updates, use the pkg update command, as follows: # pkg update Running this command updates packages that you might not otherwise consider updating, for example, kernel components and other low-level system packages. * Adding or updating individual packagesTo add individual software packages, use the pkg install command. Any dependent packages are also updated at the same time. * install package updates that deliver fixes A pkg update operation might include bug fixes, so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases. Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network. By default, interfaces check repository catalogs in the following locations: * The default installation repository at pkg.oracle.com/solaris/release. * The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express support contracts, and it contains packages with the latest bug fixes. For this reason, a support contract must be purchased for production deployments.
