Advice regarding benefits of RAC in non-production environments.
We are starting work for a new client using rdbms 11.2.0.2 and e-bus 12.1.3 and are currently configuring our non-production environments for support/development/testing purposes and it has been suggested that our 5 non-production environments should all be RAC'd as per production. I personally could understand having maybe one or two RAC'd environments but wouldn't have thought that having all of them RAC'd was really necessary as presumably this will mean an unnecesary overhead on resource? Does anyone have any views/experience of best practises for non-production environments please?
