Oracle RAC , Do I need XA driver?

I have Oracle 11g, configured to use Real Application Cluster (RAC) and storage.

I thought XA is for 2PC transactions , for multiple data sources/managers.

In theory you wouldn't have to use any different driver for Oracle RAC, because it should resolve clustering and scaling behind the scenes.

You need XA transactions when you have several different data sources which should be used under one transaction.

Do you experience any issues when using non-XA driver with Oracle RAC?
