rac vs dataguard

    We are planning to implement a 2 - node rac cluster, EE 10.2.0.4, solaris 10, using ASM.

    The plan is to also use dataguard to create a logical standby db for reporting.

    I was considering the idea of creating a 3rd member of the rac cluster, and dedicate it to reporting, instead of using dataguard. There would be the additional cost for rac, but the adminstration may be simpler.

    Has anyone done this ? What are the pros and cons ?    

    Thanks for your feedback.
