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.
