As a long-time Sun customer, you decide enough is enough with Trusted Solaris 8 having been EOL-ed in May of 2009 and want to move your MLS-centric Oracle RAC implementation to the next version of Trusted Solaris, which is Solaris 10 11/06 with Trusted Extensions.
You order Sun Solaris 10 11/06 w/Trusted Extensions, update your Oracle RAC license, buy a Sun SPARC server, (probably some Niagara-based product because Sun can “prove” it’s the best there is). Two weeks later your sales and technical support team from Sun is laid off, the result of stalled EU issues with the Oracle acquisition.
Subsequently, you note there seems to be a problem installing Oracle RAC in a Solaris Container (Zone) unless it’s installed in the global Zone and even then your customer finds out that Oracle only supports non-RAC databases in Solaris Containers. Not only is RAC not supported but even if one installs “regular” Oracle, it being run in a global zone will violate Sun MLS implementation for Sun basically replaced its traditional Trusted Solaris 8 fine-grained MLS with each Classification (sensitivity) set in its own Zone, that is, its own instantiation of Solaris.
Even extracting a tar-ed Trusted Solar 8 MLS file system would fill a Solaris 10 w/TE screen with permission errors due to the radically different method of course-grained classifications used in Solaris 10 w/TE.
Frantically you call “an old friend” from IBM and explain your Sun problem. IBM responds that it has no problem, nor makes any excuses, about running Oracle RAC in an MLS AIX or MLS Linux environment.

“Starting with Solaris10, Oracle can be installed within a Solaris Container (soft OS partition). However, only non-RAC databases are supported (RAC is only supported in a global zone)”
 see: http://hub.opensolaris.org/bin/view/Community+Group+zones/faq#H
“Q. Can I use Oracle RAC in a Container?
A: This is really three questions: (1) does it work (2) in what configurations does Sun support the Solaris components (3) in what configurations does Oracle support this? The short answers are:
Oracle RAC has been demonstrated consistently using the Solaris OS, the Solaris Zones Cluster feature of Solaris Cluster software and Oracle RAC
Sun supports ’Solaris Zone Clusters" using Solaris Cluster
Only Oracle can determine the level of support available for Oracle RAC in Solaris Zones Clusters.”
[note: Result: Cannot run RAC under Solaris10 w/TE with MLS. Running everything in the same zone (especially the global zone) violates MLS classifications (sensitivities). Running RAC in a Solaris Cluster Zone is not a MLS Solaris Zone.]
Moving Oracle RAC from Trusted Solaris 8 to Solaris 10 w/Trusted Extensions is a No-Go
