3. New Features and Enhancements
This section provides an overview of the top new features in this release of Red Hat Satellite 5.
3.1. Content Delivery Network Support
Previously, Red Hat Satellite 5 connected to the Red Hat Network (RHN) for general management and synchronization of content. With this release, Red Hat Satellite 5.8, and Satellite 5.8 only, has now been re-tooled to communicate with the successor to the Red Hat Network - the Red Hat Customer Portal and Content Delivery Network (CDN). Red Hat Satellite 5.8 now synchronizes content exclusively from the CDN, and no content is synchronized from RHN.
The CDN sync process used by Satellite 5.8 is configured to work with products that are available in Satellite 5 today and are not at their end-of-life (EOL). All currently mirrored content will be available after upgrading to Satellite 5.8, but after the upgrade you will not be able to re-sync content that is at or beyond its EOL. If you are planning a new install of Satellite 5.8 rather than an upgrade, and need to be able to sync this content, contact your account team to determine the best practices for your situation.
With this release, customers synchronizing two or more Satellite Servers with each other will have two synchronization mechanisms at play:
cdn-syncfor synchronization with Red Hat, and
satellite-syncfor synchronizing with other Satellite Servers or from dumps.
3.2. Certificate Generation
This release introduces a new process to generate a Red Hat Satellite Manifest and activate your Satellite Server. It also introduces tooling changes that allow the rhn-satellite-activate script to refresh and download manifests from the Customer Portal. These enhancements are included as part of the transition from RHN.
With this release, you can now monitor the health and well-being of the "behind the scenes" task management daemon Taskomatic using a new command-line tool,
taskotop. As the name implies, the utility of this tool is similar to that of the Linux utility
topin that you can introspect the state of the Taskomatic daemon.
3.4. Updated Back-End Technology
This release includes updates to the following supporting interfaces and underlying technologies:
- Default database: PostgreSQL 9.5 DB from Software Collections (embedded, managed)
- External DBA-managed Oracle support: Oracle 12c (continued supported interfaces for 10g and 11g)
- Remaining mod_perl stack rewritten to Java
- IBM Java 1.8.0 runtime environment
