3.13. Solaris 8 and Solaris 9 containers as revision systems
Requirement
[ug] For legal reasons or due to revision requests, it is necessary to have certain systems available
for years under Solaris 8 or Solaris 9.
• Operating old systems under Solaris 8 or Solaris 9 is expensive (maintenance costs).
• Old hardware perhaps has not a maintenance contract.
• Migration to more up-to-date systems is expensive.
• Migration to an up-to-date operating system or to up-to-date hardware requires a new software
version.
Solution
[ug] Legacy systems are run in Solaris 8 or Solaris 9 containers on an up-to-date Solaris 10 system.
The details:
• Branded zones, that is, the environment of an older Solaris is active within the zone.
• Installation of an archived legacy system.
• CPU resource management based on Solaris Fair Share Scheduler.
• Memory resource management.
• Application administrator or the administrator of the previous legacy system administrator get
root access in the zone.
