How to run Exacheck for Exadata Oracle machine ?

1. Log to lst node of Exadata as root
    cd /opt/oracle.SupportTools/exachk
    ./exachk -v   
2. Check with oracle Doc ID 1070954.1 to see if current exachk version latest        
    if not,  dwonload (there is a link in the above note) exachk.zip
    and fpt to 1st node of Exadata /opt/oracle.SupportTools directory
           #mv exachk exachkold
           #mkdir exachk
           #mv exachk.zip exachk
           #cd exachk     
           #unzip exachk.zip
           ./exachk -v
3.  Set timeout big enough so exachk watchdog will not time out:
               #export RAT_TIMEOUT=28800  -- 8 hours
               #export RAT_ROOT_TIMEOUT=28800
               #export RAT_PASSWORDCHECK_TIMEOUT=28800  (if X3 and X5, number can be smaller in seconds)
4. Run at background
               #nohup ./exachk &
5. Check last few lines of nohup.out for location of exachk report
     output looks like:
         Detailed report (html) - /opt/oracle.SupportTools/exachk_servername_dbname_030417_031918/exachk_servername_dbname_030417_031918.html
         UPLOAD(if required) - /opt/oracle.SupportTools/exachk_servername_dbname_030417_031918.zip
      upload the last one to oracle SR.

Exachk completes partially or failed due to old exchk process spawning in other nodes ..Please check and kill it

Find the process and kill it
[root@server1 exachk]#kill -9 <PID> --- which is used to kill the above session
