Thanks to all those who replied, maybe i was not clear in my original email. Basically all i want to be able to do is stop the CRS daemon on nodes 1 and 3 (so the instances on these nodes will be single RACed instances) and also have the CRS daemon running on nodes 2 and 4. I know i can do something like init.crs on the nodes i want to stop the CRS daemon (nodes 1 and 3) Do I have to shut down all the instances beforehand before i can issue the init.crs stop? Will the other instances on nodes 3 and 4 still be under CRS control?

My specific question are, do i have to de-install the RAC software and CRS software on the nodes which are not going to have the RAC databases, but my ORACLE_HOME and CRS_HOME are on a shared filesystem, so i guess this can't be done! Am not using ASM. TIA --------------------------------- Yahoo! Model Search - Could you be the next catwalk superstar?
