Diff —
Use this subtab to validate configuration files on the selected systems against copies in
your central repository on RHN. The table lists the configuration files associated with any
of the selected systems. Clicking its system count displays the systems already subscribed
to the file.
To compare the configuration files deployed on the systems with those in RHN, select the
checkbox for each file to be validated. Then click Analyze Differences and schedule the
action. Note that the files compared are of the latest version at the time of scheduling and
do not account for versions that may appear before the action takes place. Find the results
within the main Schedule category or within the System Details

Events tab.

Config Channels

Subscriptions —
Subscribe systems to configuration channels according to order of preference. This tab is
available only to Organization Administrators and Configuration Administrators. Enter a
number in the Rank column to subscribe to a channel. Channels are accessed in the order
of their rank, starting from the number 1. Channels not assigned a numeric value are not
associated with the selected systems. Your local configuration channel always overrides
all other channels. Once you have established the rank of the config channels, you must
decide how they are applied to the selected systems.
The three buttons below the channels reflect your options. Clicking
Add with Highest
Rank places all the ranked channels before any other channels to which the selected sys-
tems are currently subscribed. Clicking Add with Lowest Rank places the ranked chan-
nels after those channels to which the selected systems are currently subscribed. Clicking
Replace Existing Config Channels removes any existing association and starts cleanly
with the ranked channels, leaving every system with the same config channels in the same
order.
In the first two cases, if any of the newly ranked config channels is already in a system’s
existing config channel list, the duplicate channel is removed and replaced according to the
new rank, effectively reordering the system’s existing channels. When such conflicts exist,
you are presented with a confirmation page to ensure the intended action is correct. When
the change has taken place, a message appears at the top of the page indicating the update
was successful.

Base Channel Alteration —
Channel Administrators may change the base channels to which the selected systems are
subscribed via this subtab. The default Red Hat base channel selection in the pulldown
menu subscribes the system to whichever Red Hat-provided base channel represents the
