DESCRIPTION
Oracle Enterprise Manager 12c is system management software that delivers centralized monitoring, administration, and life cycle management functionality for the complete Oracle IT infrastructure, including engineering systems. With a broad set of end-to-end monitoring, administration, configuration management, provisioning, and security capabilities, Enterprise Manager Cloud Control reduces the cost and complexity of managing computing environments. Oracle EM12c is using a holistic approach to manage Oracle Exadata Database Machine allowing administrators to monitor and manage Exadata hardware and software from single console.

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…

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
Scenario_1 Analyze only at working 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
