Oracle RAC Licensing
Oracle offers two main licensing metrics for RAC: Processor Licensing and Named User Plus Licensing. RAC operates as an add-on license to Oracle Database Enterprise Edition (DB EE); the RAC license quantity and metric must match the DB Enterprise Edition license.
For instance, if your Oracle DB EE is licensed per processor, your Oracle RAC must also be licensed per processor.
- Processor Licensing: This type of licensing is based on the total number of processors used. To apply this, one must consult the Oracle Core Factor Table.
- Named User Plus Licensing: In this case, licenses are granted to individual users. The number of Named User Plus licenses must equal the number of users accessing the Oracle Database.
Remember, all nodes in a cluster must have Oracle RAC licenses.
Oracle RAC License Costs
The cost of Oracle RAC licensing depends on the chosen metric:
- The Named User Plus license costs $460 per Named User Plus.
- The Processor License costs $23,000 per Processor.
Remember, these prices may vary, and it is always best to consult with Oracle or an authorized Oracle reseller for the most accurate pricing information.
