Sun Microsystems SOLARIS 10 - Manual (Page 34)

Version 3.1-en Solaris 10 Container Guide - 3.1 3. Use Cases Effective: 30/11/2009
3.12. Solaris 8 and Solaris 9 containers for development
Requirement
[ug] There are still systems running in companies under Solaris 8 or Solaris 9 with self-developed
software, and it must be possible for these systems to continue software development or debugging.
• The operation of old systems under Solaris 8 or Solaris 9 is still necessary
• Rarely used development systems are relatively expensive (ongoing maintenance)
• Migrating the development to current systems does not guarantee executability of the software
developed on the old systems.
Solution
[ug] On a current system under Solaris 10, Solaris 8 or Solaris 9 zones are set up with the
development environment installed for the appropriate operating system. The details:
• Branded zones, that is, the environment of an older Solaris version is active within the zone.
• Installation of an archived legacy system.
• CPU resource management based on the Solaris fair share scheduler.
• Memory resource management.
Assessment
[ug] This use case has the following characteristics:
• Applications are operated and further developed using the original version. Costly migration of
the application to a new version is not necessary.
• The original development software can continue to be used; there are no compatibility problems.
• Current hardware based on Solaris 10 can be used.
• Environmental costs such as electricity and cooling are lower, and capacity is higher than with
an old computer.
• The advanced software can be installed and operated both on a system under Solaris 8 or
Solaris 9 as well as in a system with a corresponding branded zone.
