5. ExaChk Tool
Where to get it:
MOS Note ID: 1070954.1 – Exachk or Healthcheck
Current release: 2.2.5.2_20140815
When to run:
On a regular basis (30 days)
After corrective actions performed on a failure

6. ExaChk Tool
Run ExaChk:
$ cd <exachk unzip location>
$ ./exachk –a
Note: Follow the prompts and provide passwords

7. Exachk Outputs

8. Enterprise Manager 12c Approach

9. Prerequisites
Note: 757552.1 - Oracle Exadata Best Practices
Note: 1110675.1 – Oracle Database Machine Monitoring Best
Practices
Oracle Exadata Configured and Monitored
Oracle Engineered System Healthchecks Plug-In (12.1.0.5.0)
Oracle Enterprise Manager 12c (12.1.0.2, 12.1.0.3, or 12.1.0.4)

10. Environment Info
RAT_COPY_EM_XML_FILES : Enables copying of result files on all the
cluster
export RAT_COPY_EM_XML_FILES = 1!
RAT_OUTPUT : Output path for the exachk output
export RAT_OUTPUT = /U01/ORACLE/EXACHK_RPT!

11. Daemon
Exachk daemon makes it possible to run the ALL (-a) option of the
Exachk tool in silent mode.
Start the daemon as the Oracle user (follow the prompts)
./exachk –d start!
Run Exachk by using the daemon
./exachk –daemon –a!
Note: Same process can be used to run Exachk on Exalogic

12. Daemon (Cluster)
Run the daemon as the Oracle user with cluster support
./exachk –clusternodes [node1,[node N]] –d start!
Run Exachk by using the daemon
./exachk –daemon –a!
Note: Now exachk can run across all nodes in the exadata (if needed)

13. Plug-In
Check for any new plug-ins
!Setup -> Extensibility -> Self Update -> Plug-Ins!
!Search for HealthChecks!
!
Apply to OMS and Target Agents
!

14. Agent Interaction
Results are placed in the metric: ExadataResults!
Force the agent to collect Exadata metrics
./emctl control agent runCollection
<targetName>:oracle_exadata_hc ExadataResults!
Note: <targetName> = Target in OEM12c

15. EM Output
Reports:
All Targets -> Engineered Systems -> Oracle
Engineered System Healthchecks!
!
Can be saved as CSV files
Key Areas: Summary, Incidents & Problems, Result Summary

16. EM Output
Alerts:
Default via Plug-In (15 total)
1.Verify Disk Cache Policy on DB Server!
! !2.Verify DB Server Disk Controllers use
! !writeback cache!
! !3. Verify RAID Controller Battery Condition
! !and Temperature!
! !...!
! !13. Exachk not running!
! !14. Results and Exception file(s) missing!
! !15. Metric Parsing Failed!
! !!
Note: Unwanted alerts can be disabled with monitoring templates!
