Oracle customers who are fortunate to have an Oracle Exadata Database Machine, will need to run “exachk” from time to time, which is pronounced as Exa-Check.  This tool checks your Oracle Exadata Database Machine configuration, software, critical issue and provides a Maximum Availability Architecture score.  It is required to run before and after Exadata patching and is good practice to run on a frequent basis and review the recommendations.

More info here:

Oracle Exadata Database Machine exachk or HealthCheck (Doc ID 1070954.1)

“exachk holistically evaluates all Oracle Engineered Systems.   

It includes:

• Configuration checks for Database Servers, Storage Servers and InfiniBand Switches
• Grid Infrastructure, Database and ASM and operating system software checks
• MAA Scorecard which conducts an automatic MAA Review
• Exadata Software Planner, Software prechecks, Exadata and Database Critical Issue alerts

All checks have explanations, recommendations, and manual verification commands so that customers can self-correct all FAIL and WARNING conditions reported. 

Development recommends that the latest exachk be executed with the following frequency:

• Monthly
• Week before any planned maintenance activity
• Day before any planned maintenance activity
• Immediately after completion of planned maintenance activity or an outage or incident”

The download can be obtained from the above MOS note 1070954.1.  Place the download zip file as root on a compute node, in the Oracle’s Home for example, I use “/home/oracle/version1/exachk”.  Within this folder create another folder called exachk, which allows you to easily replace the tool with the latest version and unzip the zip file to this folder:

[root@v1ex2dbadm01 exachk]# pwd
/home/oracle/version1/exachk
[root@v1ex2dbadm01 exachk]# rm -rf exachk
[root@v1ex2dbadm01 exachk]# mkdir exachk
[root@v1ex2dbadm01 exachk]# ls -lh
total 19M
drwxr-xr-x 2 root root 4.0K Sep 5 10:53 exachk
-rw-r--r-- 1 root root 19M Sep 5 10:51 exachk.zip
[root@v1ex2dbadm01 exachk]# unzip exachk.zip -d ./exachk

Once completed, you’ll see a new folder and zip file, I recommend moving them both up a level to safe keeping:

In the new folder you’ll see a html file, which is the report produced by exachk:

It’s normally easier to copy the zip file off the compute node to your machine and then unzip and view the report local.

It will look like this:

Known Issues

1. Running ExaChk reset snmpd.conf and iptables on Storage Cells.  There’s a bug currently open with Oracle Support for this:
Bug 26742216 – EXACHK IS RESETTING IPTABLES AND IT IS BLOCKING SNMP CONNECTIONS UNTIL RESTART

Which hasn’t yet been fixed.  See my blog post with discuss how to fix this after Exadata Patching where this also happens:
SNMP unresponsive on Storage Cell after Exadata Patching

2. ExaChk experiences Skipped Checks and Timeouts.  Se my blog post which show how to workaround this issue:
Resolving Slow Performance, Skipped Checks and Timeouts on Exa Check (exachk)
