According to the Oracle Documentation at the licensing for OSB Cloud Module is by concurrent SBT channel.

There are a variety of excellent optimizations available both for running Oracle on EC2/EBS and for improving backup performance to S3. Unfortunately, the best optimization for RMAN backup to S3 is to use many channels (which increases license cost). Some other approaches:

  • Use incrementals
  • Back up mainly archivelogs and take datafile backups only as often as required to achieve acceptable MTTR
  • Use compressed backup sets
  • Use only as many channels as you must to achieve acceptable backup time, and add more channels as you grow
  • Work with Oracle to reduce license costs by agreeing to be a reference customer for OSB to the cloud

I am concentrating on Oracle on Amazon Cloud this year for writing and presentations. I will be doing extensive research and testing on performance and architecture, especially as it pertains to I/O to EBS and S3, but also addressing issues of persistence and Oracle version deployment. Anyone with Amazon cloud questions feel free to ask me.
