Why exachk?

Exachk is a comprehensive utility on an Exadata Systems for validating hardware, firmware, software and the configuration settings.

Normally after a system setup as a post installation step exachk validates the setup. If for any reason exachk isn’t installed on the compute node you can download it on My Oracle Support. The My Oracle Support note id : 1070954.1.

If installed you can locate the Software under the directory  “/opt/oracle.SupportTools” on the first compute node of an Exadata system.

Before running exachk check the installed version and if expired download and install the actual version from MOS. The current Production Version is:

[root@exachk_121021]# ./exachk -v


Starting the exachk from the command line it looks like the following output.

exachk_121021]# ./exachk -a

CRS stack is running and CRS_HOME is not set. Do you want to set CRS_HOME to /u01/app/[y/n][y]y

None of above

Select databases from list for checking best practices. For multiple databases, select 10 for All or comma separated number like 1, 2 etc [1-11][10].

Depending from the system load the exachk finished here in this example after 20 minutes.

First of all there will be a summary with some major and detailed information’s concerning the installed system.

Exadata documentation

Hi Exadata Fan’s,

in the past the Exadata documentation was only available for „Machine Owners“ so it was available on the Storage server under /usr/share/…

I learned from Tanel Poder that the Exadata documenation is now for everybody available.

This is very helpful, because otherwise you have to create a tar archive transfer it to your notebook and extract the files.

Here is the link: http://docs.oracle.com/cd/E50790_01/welcome.html

Have fun :-)
