Enterprise Manager 12c Approach

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)

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!

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

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)

Plug-In

Check for any new plug-ins !Setup -> Extensibility -> Self Update -> Plug-Ins!!Search for HealthChecks!

!

Apply to OMS and Target Agents !

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

EM Output Reports:

All Targets -> Engineered Systems -> Oracle Engineered System Healthchecks!!

Can be saved as CSV files

Key Areas: Summary, Incidents & Problems, Result Summary

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!! !!
