Architecture build on plugins

Ability to personalize pages

Different settings for different users (home page, favorites, credentials etc.)

Integration with LDAP, Oracle Access Manager and Microsoft Active Directory

Oracle Enterprise Manager 12c - Concepts

9

Repository: • Data storage, rollup and purging

Management Server (OMS): • Handles management data from

Agents • Handles administration requests

from UI • Sends out notifications

Agents: • Gather management information • Perform administration task

Oracle Enterprise Manager 12c – Plug-ins

10

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 • More…

Summary & Q&A

Consolidation Planner

12

- part of Oracle Enterprise Manager 12c Cloud Control

- Included in Chargeback and Capacity Planning plug-in

Helps to optimize and consolidate current IT infrastructure. It shows how

much servers do you need and their load after consolidation.

Consolidation Planner - Concepts

13

Source server

• Current servers that should to be consolidated

Destination server

• Phantom

• Server we might buy

• Existing

• Existing server that is monitored by EM12c

Consolidation Project

• P2P (physical to physical)

• Consolidating to new physical servers or Exadata

• P2V (physical to virtual)

• Consolidating to virtual machines

Consolidation Scenario

• Different consolidation scenarios

Consolidation Planner - Metrics

14

CPU(SPECint)

Memory

Disk

Disk I/O

Network I/O

Consolidation Planner uses these metrics:

Consolidation Planner maps source load to minimum amount of destination servers.

Project_1 P2P Analyze for 30 days

Summary & Q&A

Monitoring Exadata– How does it work?

18

1. OEM Agent deployed on the Compute Node

2. Exadata Plug-in deployed with the Agent

3. Agent communicates with Storage Server and Infiniband Switch targets using ssh.

4. Exadata Plug-In also monitors the other DBM components using SNMP

5. Agent collects data and communicates with the EM Management Server

Discovering Exadata

19

Install Agent on Compute Node

Launch Auto Discovery

Assign Monitoring

Agents

Component Credentials

Monitoring Properties

Review

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)

Integrated view of Hardware and Software

20

Integrated view of Hardware and Software

21

Hardware view

Schematic of storage cells, compute

nodes and switches

Hardware components alerts

Software/system view

Performance, availability, usage by

databases, services, clusters

Software alerts for db, cluster, ASM

Topology view of DB systems/clusters

Configuration view

Version summary of all components

along with patch recommendations

Storage Cell Management

22

Storage Cell monitoring and administration support

Monitoring via Cell Home page and performance

pages

Administration actions supported: Start/stop Cell,

verify connectivity, setup SSH

Automatic discovery of Exadata storage cells by agents

on compute nodes

Management by Cell Group

All cells used by a database automatically placed in

a group

Cell Group level administration operations - you

can issue dcli (distributed cli) commands to a

group of cells from EM itself

Storage Cell – I/O Management

23

Configure Exadata I/O Resource Manager using the Database Resource Plan

Specify resource allocations per database Share based/Percentage based Disk I/O priority and maximum utilization limit

Specify optimization objective

Use “low_latency” or “balanced” for OLTP-oriented databases

Use “high_throughput” for data warehouses Use I/O metrics to track

I/O load per database (IOPS, MBPS, disk utilization %)

I/O throttling per database

Storage Cell Performance

24

Navigate to cell performance from DB

performance page

Storage Grid Health Indicators

Storage I/O load

Cell load imbalance indicator

ASM performance problems

Cell hardware and software incidents

Cell configuration problems

Network problems

Infiniband Management

25

Infiniband Network home page

Performance page: real time and historical

Topology view of Network with switch and

port level details

Alerts (switch generated and EM generated) Performance metrics Configuration metrics – detect and notify

configuration changes/best practice violations

Infiniband Management

26

Perform Infiniband Administration tasks Enable Port Disable Port Clear Performance counters Clear Error Counters

Exadata Topology

27

Hardware and software topology Recognized Incidents and problems displayed on the topology Topology View of all Exadata components by

Uses Used By System Members DB Machine Software

Monitoring: ILOM, Cisco Switch, KVM

28

Common metrics monitored Power supply failure Fan failure Temperature out of range

Specific metrics monitored Cisco Switch

Configuration change tracking and reporting

Unauthorized SNMP access Keyboard, Video, Mouse (KVM)

Server connected to KVM added/removed, powered on/off

Monitoring: Power Distribution Unit (PDU)

29

Measures power consumption used by Exadata components and provides early

warning of impending thresholds

Monitors electric current being used by equipment connected in Exadata rack

Integration with the Database Performance Page

32

Database Performance page shows

Exadata info

Exadata Database I/O Load graph over

time

I/O Breakdown – I/O MB per second

by I/O Function – shows Smart Scan

Drill down to Exadata System Health /

Exadata Healthchecks

33

Oracle Exadata Healthchecks plugin needed!!!

Run exachk in daemon mode

Schedule exachk execution

Multiple exachk results on one page

Export exachk report

Exadata Configuration Management

34

Automated Configuration Management Enforcement of Exadata configurations using Policies Detection of configuration drifts and changes

From defined golden standards Between storage servers and between database machines
