Setting up ASR
• Documentation and fault list available from www.oracle.com/asr
 Exadata specific documentation – Exadata Quick install Guide
 ASR errors and notes – by ILOM, for every supported ILOM (more than Exadata)

• One Command Integration (from 11.2.3.1 forward)
 Now works with latest version of OneCommand
 Set up the SNMP trap forwarding
 Produces the script to register with ASR Manager

• Auditing your install
 MOS 1450112.1 - download the latest version of asrexacheck
 Verifies connectivity to Oracle back end


Enterprise Manager Architecture
EM Users: EMCLI Repository (OMR):
Console / Reports
• Heart
Firewall • Data storage, rollup and purging
Agent Management Server (OMS):
Connectors
• Brains
• Handles management data from
Agents
• Handles administration requests
Agent from UI
Repository Management
Database Server • Sends out notifications

Agents (OMA):
Internet
• Nerve endings
Agent • Gather management information
Notifications
• Perform administration task

Agenda
• Why do I care?
• Exakits
• Self Update
• Now what?


Exadata OMS kit
• Download patch 13546881 from My Oracle Support
• Installs and configures a new Enterprise Manager environment
 Includes repository database (11gR2 PSU3) and OMS
• Can be used:
 To deploy a new simple Enterprise Manager infrastructure
 Testing environment, demo, POC, …

Note: The Exadata Kits get updated after each PSU release of EM, the plug-ins and Exadata HW refreshes

Blog posting: Enterprise Manager Cloud Control 12c Setup Automation kit for Exadata


Installing OMS kit
• Read the README from the downloaded patch!
(Has all the steps detailed quite nicely…)
• After running the setupem.sh script:
 The Cloud Control OMS and Repository will be installed
 The Exadata plug-ins are deployed on the OMS
• To be done after the install completes:
 Update the Monitoring Configuration of the repository database
(and change the password for a more secure setup - default password is
‘welcome1’)
 Update the license agreement for the ‘emrep’ database for
‘Oracle Database Lifecycle Management Pack’


Exadata Agent kit
• For Agents deployment:
 Use the Agent push method from the UI (Guided new host discovery), and deploy the plug-ins
 Or use the Exadata Agent Kit (Download patch 13551607 from My Oracle Support)
• Agent kit will install and configure a new Enterprise Manager Agent
 Need to know where the OMS is, to register the Agent
 Agent will download and deploy the Exadata plug-ins
 Discover the Exadata rack and all the databases
• Can be used:
 In conjunction with the OMS kit
 Or as an ‘additional Agent install’ for an existing EM infrastructure
• Requirement:
 Version of the OMS and the OMS plug-ins has to be the same or higher then the Agent
Version information available in the header of the README file
 The Exadata configuration spreadsheet needs to be correct - Chapter 4 - Using the Oracle Exadata
Database Machine Configurator Spreadsheet from the Oracle Exadata Database Machine Owner's Guide

Note: The Exadata Kits get updated after each PSU release of EM, the plug-ins and Exadata HW refreshes


Installing Agent kit
• Read the README from the downloaded patch!
(Has all the steps detailed quite nicely…) em.param example file:
• After running the setupem.sh script: EM_VERSION=1.0
OMS_LOCATION=REMOTE_CORP_GC
EM_BASE=/myem/myemhome
 The Cloud Control Agent will be installed OMS_HOST=myoms.acme.com
(Using the /opt/oracle.SupportTools/onecommand/em.param file) OMS_PORT=4900
EM_USER=oracle
 The Exadata plug-ins will be deployed and ready to go EM_PASSWORD=welcome
 SSH equivalence for the Agent to the Cell nodes is setup
(Based on the Exadata configuration spreadsheet)
 Use the discovery wizard for adding the Exadata, GI and RAC targets
• To be done after the install completes:
 Add SNMP trap forwarding for Cisco, KVM and PDU


Plug-in Framework
Update entities:
• Download from My Oracle Support via the
Self Update feature in the UI
• Or manually upload into the repository via
EMCLI

Deploy entities:
• OMS’s side (for everyone)
• Agent side (selective)

Plug-ins for the Engineered systems:
• Exadata
• ExaCheck (Health-Check)
• Exalogic (Elastic Cloud)


Agenda
• Why do I care?
• Target discovery
• Double checks
• Now what?


Discovering Exadata System

Install Agent Assign
Launch Auto Component Monitoring
on Compute Monitoring Review
Discovery Credentials Properties
Node Agents

• Discovery Wizard (guided discovery)
• Plug-in has all the components bundled (Cell, KVM, PDU, Cisco Switch)
Exadata Cell and the Infiniband components discovered out-of-the box
• Option to discover new DB Machine or rediscover (Add DB Machine Members)


Demo

• Exadata discovery


Exadata Management
Integrated View of Hardware and Software
• Hardware view
• Schematic of cells, compute nodes and
switches
• Hardware components alerts
• Software/system view
• Performance, availability, usage by
databases, services, clusters
• Software alerts db, cluster, ASM
• Topology view of DB systems/clusters
• Configuration view
• Version summary of all components
along with patch recommendations


Post configuration steps
• Double check!
 Audit Script - 1473912.1: Prerequisite Script for Exadata Discovery with
Enterprise Manager 12c

• Make sure the traps are set!
 Add SNMP trap forwarding for Cisco, KVM and PDU

• Need an executive view? – Build a dashboard!
 MOS 1458346.1 Build a monitoring dashboard with EM 12c


Agenda
• Why do I care?
• Diagnosing Discovery Issues
• EMDiag
• Now what?


Diagnosing Exadata discovery
• Physical RACK configuration out of sync with logical XML representation
 After every manual change to the Exadata RACK, the databasemachine.xml file should get
regenerated. (See chapter 4 of the Database Machine owner’s guide)
• Use the Admin network hostnames for the components
 Do not use the public hostnames for the Exadata components
• SSH setup problems between the components
 Compute nodes need SSH equivalence setup with the cell monitor user on the Exadata Cell
machines, as well as access to the nm2user account on the IB network switches
• Permission problems with the software on the compute node
 Agent software owner requires read access on the databasemachine.xml file and the kfod
executable from the RDBMS database home

EMDIAG - Exadata Diagnostics
• Diagnostics tools for Enterprise Manager
 Tool for each tier: AGTVFY, OMSVFY, REPVFY
• Exadata specific diagnostics
 On the repository side:
$ repvfy verify exadata [-level {0-9}] [-details]
$ repvfy dump exadata –name "<db machine name>"
$ repvfy show exadata_master_agent –name "<db machine name>"
 On the Agent side:
$ agtvfy verify exadata [-level {0-9}] [-details]
$ agtvfy version exadata
