unless I am missing your question, you can simply relink Oracle rac_off. If libskgxn.so is a stub (rac_off), CRS is not an issue. You'll still have multiple threads of redo, but no matter... it wont be RAC. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Zabair Ahmed Sent: Wednesday, November 16, 2005 1:31 AM To: oracle-l@xxxxxxxxxxxxx Subject: RAC de-clustering 10.1.0.3.0 on TRU64 V5.1 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 ________________________________ Yahoo!
