Oracel RAC implementation experience

Dear All,

Has any one successfully implemented Oracle RAC on Solaris 10/SPARC on a production box for SAP ECC/SRM etc...?. Can u Pl share your experience? Will Oracle RAC be supported in future or is it going to be phased out by SAP? How robust is the Oracle RAC implementation? Is it advisable to take the Oracle RAC route?

Thanks for all your inputs.

Regards

Velu
