Administration and Diagnostics Utilities - Oracle Exadata Recipes: A Problem-Solution Approach - page 168

Then, generate your snapshot providing a URI to upload the snapshot information to. In the example below,
we're selecting an Oracle ZFS Storage Appliance share with ftp services enabled on it:

-> set /SP/diag/snapshot dump_uri= ftp://11.11.1.170/export/esx_hosts/
Enter remote user password:

How It Works
On Oracle's Integrated Lights Out Management software built on each Exadata Compute, Storage, and InfiniBand
node, ILOM software provides the ability to generate and bundle snapshot diagnostics information. The service
snapshot diagnostics utilities collect log files and run various commands, assimilate the output, and transfer to a data
collection location as specified by the administrator.
An Exadata DMA would typically only need to run these utilities under the guidance of Oracle Support.
In general, this is a required step when filing a hardware-related Oracle Service Request.

7-9. Performing an Exadata Health Check Using exachk
Problem
You want to conduct a comprehensive Exadata health check on your Exadata Database Machine to validate your
hardware, firmware, and configuration.

Solution
Oracle's exachk utility is designed to perform a comprehensive health check of your Exadata Database Machine.
In recent versions of Exadata, exachk is located under /opt/oracle.SupportTools on your first compute node.

■ Oracle aCS typically runs the exachk utility as a post-installation step to validate the Exadata
installation. historically, this functionality was provided with the HealthCheck utility, located in
/opt/oracle.SupportTools/onecommand/HealthCheck . HealthCheck has been phased out and replaced with exachk .

Note

If you do not have the exachk utility installed on a compute node, you can download the exachk from My Oracle
Support document 1070954.1. After downloading the latest version of exachk , transfer the zip file to one of your
compute node servers and unzip it.
After unzipping, you can determine the version of exachk by running exachk -v :

[root@cm01dbm01 stg]# ./exachk -v
EXACHK VERSION: 2.1.6_20120817
[root@cm01dbm01 stg]#
