Reconfigure an Exadata Database Server to Use UEK Kernel After Previously Choosing to use non-UEK Kernel
Last updated on JANUARY 02, 2014
Applies to:Oracle Exadata Storage Server Software - Version 184.108.40.206.0 to 220.127.116.11.1 [Release 11.2]
The process is defined to allow an Exadata Database Server that has been converted to non-UEK at some point after an upgrade to 18.104.22.168.0 or 22.214.171.124.1 to convert to using the UEK kernel. This conversion can be done with the steps below only on the same Exadata release the database server is running on. To incorporate the conversion as part of an upgrade, you must either convert to UEK prior to upgrading the compute node to the new release, or perform the conversion to UEK after completing the upgrade process. The conversion should be performed using the Exadata ULN repository for the version currently displayed by the imageinfo command on the database server. These steps will only need to be executed once to perform the conversion, from that point forward all upgrades will keep the database server running with UEK kernel.
If you plan to upgrade to 126.96.36.199.0 or later and you are running the non-UEK kernel from any 11.2.3.X.X release, the upgrade to 188.8.131.52.0 or later will automatically convert your kernel to UEK2, there is no need to use the process documented here. You should only use these steps if:
1. Your current Exadata version on your database server is 184.108.40.206.X
2. You converted your Exadata database server kernel to non-UEK after upgrading to 220.127.116.11.0 or 18.104.22.168.1
3. You will remain on your current Exadata database server version and just wish to convert from the non-UEK kernel to the UEK kernel
Re-configure an Exadata Database Server from non-UEK kernel to use the UEK Kernel when your Exadata Database Server is running 22.214.171.124.0 or 126.96.36.199.1.
