rman duplicate from RAC to RAC

Hello All,

I have a 8-node RAC 11.2.0.4 and i'm trying to duplicate using a media backup to another 8 node uat cluster, different name, different asm diks groups, using OMF, i want to know if it is possible to run duplicate using the parameter cluster_database=TRUE.

I tried to explain what/how we do currently.

1) we setup cluster_database=FALSE in the pfile and bring the instance to nomount and run the duplicate using rman command..lines truncated due to lengthy post...
