Major Features

The following are the major features of Red Hat Network 5.0.4.

Extended Update Support (EUS) User Interface enhancements

A major purpose of this RHN release is to address customer concerns and issue regarding the UI. Navigation to desired data via the Software Channels, SDC and/or SSM sites was very difficult, due to the large amount of target data associated with some customers. We have heard your pleas, and RHN 5.0.4. comes to the rescue! The query dropdown fields on the Software Channels, SDC and SSM pages now provide greater logic; resulting in quicker results.

These apply to systems being migrated to and from EUS channels. The rules and Use Cases assume the existence of a valid base channel.

  • Maker (e.g. Red Hat, JBoss, Alfresco)
  • Product name (e.g. Red Hat Enterprise Linux, JBoss Application Server)
  • Product trimline (e.g. AS, ES, WS, Desktop, Server, null?)
  • Version number
  • Target architecture

  • When migrating systems to or away from base channels, taxonomy provides the ability to maintain the systems child channels.
  • Improves the UI by acting as a tool for both Red Hat and our customers, to control the amount of data presented in a given screen [Software Channels, SDC, SSM].
