Types of licences do not matter AFAIK.
If your LDOM is hard partitioned with two SPARC cores, you must pay 1 processor to be legal.

You shall treat that 2 core LDOM same as you would treat physical machine with 2 sparc core.

That is the point of hard partitioning (among other things).

Problem of licence model determination has gone berserk in the past years.
Especially since most of machines are now multisocket/multithread.

This is not just Oracle, but other proprietary vendors.
Not even their own employees know how something should be licensed...

Oracle database has so many licence models and additional paid features.
One can, unintentionally .. not knowing, make an AWR report which will happily work, but will render your database not compliant if you haven't paid the database diagnostic licence.

Ask you Oracle rep about information if you can, it is his job to provide it.

Hope the helps
Regards
Peasant.

SPARC T systems run a hypervisor, so even the primary partition is virtualised!
Yes, named user plus works in a 'virtual' environment.
The caveats here are:
  • Oracle only deal in whole integer units w.r.t. cores. If you use a 4 vCPU LDom (i.e. 0.5 of a SPARC T core) you still use 1 core licence on that system
  • The users count has a minimum like er.. 20 (I think) <ouch!>
Acceptable technologies to 'hard' partition a Solaris 'instance' - according to Oracle - also include zones with either a dedicated-cpu or capped-cpu setting.
The dedicated-cpu setting apparently fixes the CPUs that will run RDBMS threads.

Ironically the capped-cpu setting caps concurrent threads. It allows Oracle RDBMS to run on any CPU core it can see, capping the concurrency.
The irony of this setting is that in a VMware cluster (not ESX server but whole cluster of them) Oracle claim that there is a potential for RDBMS threads to run on any CPU in the cluster and thus they total the CPUs in the cluster to calculate the licence fee.
Hmmm...

Note that the OS hardware and state are recorded in an audit table within an Oracle RDBMS. Oracle are happy to query that and back charge if you are tardy in getting your resource utilisation under control. Then there are licenced features... but you didn't ask about those in this post! Linux
