I wanted to use two Oracle SPARC T5-4 servers to simultaneously host both Oracle RAC and a WebLogic Server Cluster. I chose to use Oracle VM Server for SPARC to create a cluster like this:

There are plenty of trade offs and decisions that need to be made, for example:

• Rather than configuring the system by hand, you might want to use an Oracle SuperCluster T5-8
  
  
• My configuration is similar to jsavit's: Availability Best Practices - Example configuring a T5-8 but I chose to ignore some of the advice. Maybe I should have included an  alternate service domain, but I decided that I already had enough redundancy

Both Oracle SPARC T5-4 servers were to be configured like this:

Cntl 0.25  4  64GB

App LDom                    2.75 CPU's                                        44 cores                                          704 GB

DB LDom      One CPU          16 cores          256 GB

The systems started with everything in the primary domain:

Added an additional service processor configuration:

# ldm add-spconfig split

# ldm list-spconfig
factory-default
primary
split [current]

And removed many of the resources from the primary domain:

# ldm start-reconf primary
# ldm set-core 4 primary
# ldm set-memory 32G primary
# ldm rm-io pci@340 primary
# ldm rm-io pci@380 primary
# ldm rm-io pci@3c0 primary
# ldm rm-io pci@400 primary
# ldm rm-io pci@440 primary
# ldm rm-io pci@480 primary
# ldm rm-io pci@4c0 primary
# init 6

Needed to add resources to the guest domains:

# ldm add-domain db

# ldm set-core cid=`seq -s"," 48 63` db
# ldm add-memory mblock=0x180000000000:256G db

# ldm add-io pci@480 db
# ldm add-io pci@4c0 db

Needed to set up services:

# ldm add-vds primary-vds0 primary
# ldm add-vcc port-range=5000-5100 primary-vcc0 primary

Needed to add a virtual network port for the WebLogic application domain:

Add some additional spice to the pot:

# ldm set-variable auto-boot\\?=false db
# ldm set-variable auto-boot\\?=false app
# ldm set-var boot-device=HDD1 app
