the variables will be substituted with the actual hostname and IP address of the system, as recorded in

RHN’s System Proﬁle, such as:

hostname=test.example.domain.com

ip_address=177.18.54.7

To capture custom system information, insert the key label into the custom information macro

(rhn.system.custom_info). For instance, if you developed a key labeled "asset" you can add it to the

custom information macro in a conﬁguration ﬁle to have the value substituted on any system

containing it. The macro would look like this:

asset={@ rhn.system.custom_info(asset) @}

Upon deployment of the ﬁle to a system containing a value for that key, the macro gets translated,

such as:

asset=Example#456

To include a default value, for instance if one is required to prevent errors, you can append it to the

custom information macro, like so:

asset={@ rhn.system.custom_info(asset) = ’Asset #’ @}

This default will be overridden by the actual value on any system containing it. For instructions on

developing custom system information keys, refer to Section 6.4.9 Custom System Info —

Using the Red Hat Network Conﬁguration Manager (rhncfg-manager) will not translate or alter

ﬁles, as that tool is system agnostic. Binary ﬁles cannot be interpolated.

6.7. Schedule

If you click the Schedule tab on the top navigation bar, the Schedule category and links appear.

These pages enable you to keep track of the actions taking place within your systems. An action is a

scheduled RHN task that is to be performed on one or more client systems. For example, an action

can be scheduled to apply all Errata Updates to a system.

Red Hat Network keeps track of the following action types:

1. Package Installations — For more information on how to perform package installations, refer

to Section 6.6.5 Software Packages.

2. Errata Updates — For more information on how to apply Errata Updates, refer to Section 6.5.2.1

Apply Errata Updates.

3. Hardware Proﬁle Updates — To schedule a hardware proﬁle refresh, go to a system list under

the Systems category, click on the name of the system, click the Hardware tab of the System

Details page, and click the Schedule Hardware Refresh button.

4. Package List Proﬁle Updates — To schedule a package list proﬁle refresh, go to a system list

under the Systems category, click on the name of the system, click the Packages tab of the

System Details page, and click the Update Package List button.

Each page in the Schedule category represents a type of action.
