it is there on both R1 and R2, but if you do a ps , you'll see that you are still not completely free of CRS... you have to commend out the inittab entries and reboot to be completely clusterware-free ...

	IIRC, init.crs stop is not supported on 10.1.  It's only a 10.2

feature isn't it?

Of course, I could be wrong! ;)

	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?

Scenario.

currently i have a number of RACed databases (3 in total) which are running 10g RAC on a 4-node (say node 1, node2, node3 and node4) TRU64 Cluster.

what i want to be able to do is take 2 of these databases out of RAC mode (on node 1 and 3 and leave the third database RACed (on nodes 2 and 4)

Is this possible, if so can someone give me some pointers on how.

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
