Rating: 10 out of 10
IncentivizedUse Cases and Deployment Scope
Being an Oracle consultant, I have come across many times where customers seek solutions to problems where they face issues with scalability or load balancing or performance issues on their application. Oracle Real Application Clusters also helps with failover solutions with almost no outage to the business. This allows customers to run a single Oracle Database across multiple servers in order to maximize availability and enable horizontal scalability.
Pros
- Horizontal scalability
- Seamless failover
- No impact on business during failover
Cons
- Oracle Real Application Clusters is totally dependant on DBA's . It would be great if it can be simplified somehow
- Its license cost
- Enabling usage in standard edition
Likelihood to Recommend
Currently, as per RAC configuration, one node RAC or multinode RAC configuration is there. Customers who don't have licenses to run RAC simultaneously in multiple servers at the same time can opt for one node RAC configuration while they can still have the flavour of failover.
