Postconversion Steps

After completing the conversion of your single instance database to an Oracle Real Application Clusters (Oracle RAC) database, follow these recommendations for configuring Oracle RAC environments.

After conversion, Oracle recommends that you follow these guidelines:

Follow the recommendations for using load balancing and Application Failover using AC or TAC as described in a previous chapter. Use the ORAchk utility to perform Oracle AI Database health check.
Use locally managed tablespaces instead of dictionary managed tablespaces to reduce contention and manage sequences in Oracle RAC as described in Oracle AI Database Administrator's Guide
Follow the guidelines for using automatic segment space management as described in Oracle AI 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 AI Databases. Therefore, you should increase the size of the buffer cache by about 10 percent, and the size of the shared pool by about 15 percent.
