RE: Oracle on Virtual Machines

Yes, my understanding is that you would have to buy 8 CPU's worth of licenses 
for the 4 quad cores and you could create however many VM's the host could 
handle. I am not very familiar with Oracle VM to speak to it's features.  We 
(Commonwealth of PA) plunged an bought an Enterprise license for VMWare so 
that's all we have. I don't know if Oracle has an equivalent to Vmotion but if 
you've only got one VM host what are you going to use it for?  You don't start 
getting the full benefit of a VM until you have a cluster and can failover to 
another physical machine.

You haven't escaped any of the organizational problems that you would normally 
experience mixing production and development tiers. We have a production VM 
cluster/SAN and a development VM cluster/SAN.  Just from an administrative 
point of view in the event of a failure it's not good practice to cripple both 
your developers and users with one issue.

Hi Donald, Thanks. If we have the 4 Quad Core VM Host on Intel x86 platform, 
once you purchase the 8 CPU license using Oracle Licensing Metric multiplier 
(0.5/core for Intel) then we can have any number of VM with the any number 
virtual CPUs. OR for every VM's virtual CPU, you need to buy the license for.

Oracle VM is similar to VMWare? Does it have all the features of VMWare 
(especially Vmotion)?

Though the SQL server is out of the scope for discussion, Any cons you have 
found of using SQL Server VMs combining both development,test and production in 
a single physical server assuming enough hardware resources are in place. We 
are looking at the options for SQL Server as well to consolidate 10s of SQL 
Servers.

Raja.

There should be a long discussion on Oracle on VM in the May archives.
Oracle discourages the use of VMWare through licensing restrictions which it 
does not apply to itself if using Oracle VM.  You have to buy a license for 
every CPU on the VM host whether or not you are using it. I think the Oracle VM 
uses a config file to set the number of CPU's that Oracle uses.  We don't have 
any production Oracle VM's but have some
development on VM clusters.   We have a lot of production SQL Server
VM's.

Hi List,

Does Oracle support running the Oracle databases on VMs using SAN?
Oracle also has something called Oracle VM. How does it different from Vmware 
solutions?. 

Also, Looking to move the hardware from HP  PA RISC architecture to x86 using 
Linux. What is the equivalent of 4 Dual Core PA8900 processeors compared to the 
HP Machines especially DL-G Series. 

Any one has any experience of running production and development on same VM 
host; Assuming enough hardware resources in place any pros/cons of sharing the 
prod and dev on the same VM host?

Thanks in Advance.
Raja.
