Exadata Hardware - Oracle Exadata Recipes: A Problem-Solution Approach - page 10

The operating system and Exadata server software binaries are installed, patched, and maintained as images;
when you install or patch an Exadata cell, a new image is installed. You can query your current active image by
running the imageinfo command:

[root@cm01cel01 ~]# imageinfo

Kernel version: 2.6.18-238.12.2.0.2.el5 #1 SMP Tue Jun 28 05:21:19 EDT 2011 x86_64

From this output, you can see that our storage cell is running image version 11.2.2.4.2.111221 , which contains
cell version OSS_11.2.2.4.2_LINUX.X64_111221 , kernel version 2.6.18-238.12.2.0.2.el5 , with the active system
partition on device /dev/md6 and the software partition on /dev/md8 .

■ Note We will cover additional Exadata Storage Server details in Recipe 1-4.

You can also list all images that have at one point been installed on the Exadata cell by executing imagehistory :

[root@cm01cel01 ~]# imagehistory
