After completing the conversion, note the following recommendations for Oracle RAC environments, as described in the following:
Follow the recommendations for using load balancing and transparent application failover, as described in Workload Management with Dynamic Database Services
Use locally managed tablespaces instead of dictionary managed tablespaces to reduce contention and manage sequences in Oracle RAC as described in Oracle Database Administrator's Guide
Follow the guidelines for using automatic segment space management as described in Oracle Database Administrator's Guide
The buffer cache and shared pool capacity requirements in Oracle RAC are slightly greater than the requirements for single-instance Oracle databases. Therefore, you should increase the size of the buffer cache by about 10%, and the size of the shared pool by about 15%.
