Answering one of my own questions, just for your info:
I did some tests - regarding CVE-2012-1675, the listener.ora (in
<GI_HOME>/network/admin) on the newly added nodes
needs to be manually updated: the wallet location and the
SECURE_REGISTER_LISTENER* parameters need to be reinserted).
To check if everything works fine verify that the newly added database
instances register with the SCAN listeners
(lsnrctl status/services <scan_listener_name>, "service update" messages
in the SCAN listeners log files).

Hi all,
RAC 11.2.0.3.5 on RHEL 5.7 with RHEL kernel
CVE-2012-1675/COST workaround implemented (SSL communication between
listeners and instances)
The customer wants to upgrade the OS and the HW. The idea is to add
new nodes and remove the current ones.
Oracle says it could be done (RAC: Frequently Asked Questions (Doc ID
220970.1), Does Oracle support rolling upgrades in a cluster?).
I'm considering the following guide:
How to Add Node Instance or Remove Node Instance in 10gR2, 11gR1 and
11gR2 Oracle Clusterware and RAC (Doc ID 1332451.1)
(which actually points to the official documentation).
I should add the COST workaround and, I suppose, a relink of the
binaries?
Real world experience, suggestions or gotchas are welcome.
Thanks
Dimitre
