25.7.1 Providing All RPM Packages and Package Bundles
through a Catalog (Pulling)

If you want to provide all RPM packages via a catalog, create a catalog and add the mirrored Red
Hat Network bundle to it, then assign the catalog to the managed devices. This allows users to have
access through the catalog to all of the RPM packages contained in the Red Hat Network bundle.

For more information on mirroring and catalogs, see

Section 25.3, “Configuring a Software Mirror,”

on page 290

and

Section 22.2, “Creating Catalogs,” on page 265

From a managed device, there are two ways that you can force deployment and installation of the
updates included in the Red Hat Network bundles contained in a catalog:

Using the ZENworks Linux Management Update Manager:

From the managed device,

click

System

Software Update

, then select the catalog and click

Mark for installation

Run

now

Using rug:

On a managed device, start a console session and enter the

rug up

command.

For SUSE Linux Enterprise Server 10 (SLES 10) and SUSE Linux Enterprise Desktop (SLED
10) devices:

/usr/bin/rug up

For other managed devices:

/opt/novell/zenworks/bin/rug up

For more information, see

rug (1) (page 571)

25.7.2 Delivering Specific RPM Packages (Pushing)

If you want to provide specific RPM packages, you can create a custom bundle by selecting the
desired subset of RPM packages from the initial bundle that was created when mirroring the Red
Hat Network. Or, you can create several custom bundles, each containing one or more RPM
packages. It is best to test your custom bundles on a single device to verify that there are no conflicts
within a bundle. If the test is successful, you can then assign the bundles to your managed devices.

To ensure that the packages contained in the custom bundle can meet all of their dependencies, you
can create a catalog containing the mirrored Red Hat Network bundle and make it available to the
desired managed devices. During the catalog creation process, you can hide this catalog from users.
After you assign the custom bundle to devices, if a package requires other packages for dependency
resolution, the device has access to the packages in the hidden catalog. For more information, see

Section 22.2, “Creating Catalogs,” on page 265

Managed devices refresh on a schedule. Also, an administrator can trigger a device refresh through
the ZENworks Control Center. When a device refreshes, it downloads the bundle automatically from
the server and installs it.

The managed device requests one or more bundles from the server. In other words, the server does
not actually push the bundle. However, the server can tell the managed device to refresh
immediately. You can also modify the refresh interval centrally from the server for one or more
managed devices. Otherwise, the client refreshes on its own schedule to look for a scheduled action.
