I have a 2 node RAC cluster (10.2.0.1) running on AIX. For testing and documentation purposes I need to create a hot standby on the second node. I have attempted this with varying error messages. I have an SR open with Oracle but have gotten no where at all. If anyone has done this or has an idea of how to do this please reply. The instances are running on ASM with OMF. The standby also runs ASM and OMF. I am using RMAN duplicate command to try and create the standby.
