Hi, I was wondering if it is easy to migrate an database in single instance to RAC+ASM using RMAN. Is it recommended using this method for any case?? My db has around 1 TB and I have the whole weekend to proceed with it. Does anyone have any tutorial or quick reference where I can check to have an idea how to proceed? platform: HP-UX (both) Version: 11.1.0.7 (both) Thanks in advance Alex -- //www.freelists.org/webpage/oracle-l
