After running the preceding sample command, the population of the channel should be
complete. All of the packages should have been moved out of the repository; this can be
verified with the command
all RPMs have been installed and moved to their permanent locations, then this count will
be zero, and the administrator may safely remove the temporary repository (in this case,

6.3. Synchronizing
An update channel is only as useful as the freshness of the information in that channel.
Since the RHN Satellite Server is designed to be a standalone environment, any update
advisories published by RHN must be manually imported and synchronized by the admin-
istrator of the RHN Satellite Server.
During synchronization over the Internet, the RHN Satellite Synchronization Tool per-
forms the following steps:
1. Connects over SSL to central RHN Servers, authenticates itself as an RHN Satel-
lite Server, and triggers an export of RHN data — unless a local mount point for
RHN-exported data is specified, in which case no connection is necessary. Refer
to Section 6.3.2 Synchronizing Errata and Packages via Local Media for an expla-
nation.
2. Examines the export and identifies differences between the RHN Satellite Server
data set and the exported RHN data set. For a particular channel, the following infor-
mation is analyzed:
Channel metadata
•
Metadata of all packages in that channel
•
Metadata for all Errata that affect that channel
•
Note
All analysis is performed on the RHN Satellite Server; the central RHN Servers
deliver only an export of its channel information and remain ignorant of any details
regarding the RHN Satellite Server.
