The r3.8xlarage has 244 GiB of memory, 32 vCPUs, and 2 - 320 GB SSD drives. The cost is $2.80 per hour for on-demand instances. More details here:

Prior to this you had to use the i2.8xlarge instance type which also has 244 GiB of memory and 32 vCPUs. But also has 8 - 800 GB SSD drives which you will most likely not use for your Oracle Database. The cost of i2.8xlage is $6.82 per hour for on-demand instances. The other highest memory option is the cr1.8xlarge with 32 vCPUs and 244 GIB with 2 -120 GB SSD drives. The cost of this option is $3.50 per hour for on-demand instances.
One caveat here that Oracle has not released any HVM-based instance types. There are undocumented methods to create an HVM AMI from a PVM AMI but this new AMI may not be supported by Oracle.
The R3 instances include the following features:
- Intel Xeon E5-2670 v2 "Ivy Bridge" Processors
- Hardware Virtualization (HVM) only
- SSD-backed instance storage, including TRIM support
- Enhanced Networking with lower latency, low jitter, and high packet-per-second performance
