I have two node oracle rac 11g R2 environment.Now i want to add one more node.
The rac node kernel version is *2.6.18-3126.96.36.199.1.el5* but the new node (the node i'm going to add) kernel version is *2.6.18-3188.8.131.52.1.el5*.
Is this supported.Please advice.
The reason for the change in new node kernel version is i configured the repository using public-yum-el5.repo. Now the old kernel version (2.6.18-3184.108.40.206.1.el5) is not available to install
There are three questions here to consider:
1. Can it be made to work?
2. Will it be fully supported by Oracle?
3. Is it a good idea?
I've never tried that combination so I will tentatively say "yes" for #1.
Open an SR and ask Oracle Support with respect to #2
But on #3 I vote ... no way.
If the older kernel is not available ... so what? ... upgrade the older kernel to the newer one ... you should have been doing that all along to stay current with bug and security fixes.
