Kernel Upgrade for all App systems

Hi,

I have to do a Kernel upgrade soon. I have one CI DB cluster and 4 App servers. Do I have to upgrade the kernel on each app system and the CI? I mean, do I have to copy the files to the RUN folder for each App server and for the CI?

Thanks

hi.

yes, you have to copy the kernel to all your application servers. one possibility is to nfs-mount your kerneldirectory to all application servers. in this case you have to stop all servers, change the kernel once and restart. this works, if all application servers are running on the same operating system.

regards,

martin
