Application Best Practices on Oracle Exadata


One integrated system (servers, network,

storage) optimized around the Oracle Database

Intelligent, scale-out storage offloads database

processing; maintains optimal storage hierarchy

– memory, flash, disk

Industry best data compression

Superior performance, price-performance,

availability, supportability

Exadata is Oracle’s Strategic Database Platform


Building Blocks of MAA Architecture, Configuration and Operational Practices = Maximize Availability

Configuration Best Practices

Operational Best Practices

MAA Architecture

• Architecture – Enabler

• Configuration – Optimize

• Operations –Maintenance for

Stability and Availability


Maximum Availability Architecture

HA best practices for:

– Exadata Database Machine

– Oracle Database

– Oracle Fusion Middleware

– Oracle Applications

– Cloud Control

– Partner solutions

Experience from Thousands of Deployments, Validated in Oracle Labs

Migration Strategies

Migration Preparation is Essential – Simplify and optimize

– Prepare source and Exadata target

– Test and test again

Pick the Right Migration Method (Best may not be fastest) – Source platform and version

– Database size

– Availability requirement and other business requirements

Fast Network Reduces Migration Time – Having a fast network is important for quick migration, but watch out for

bottlenecks in other areas.

Oracle Resource Management

Use hugepages for optimal memory management

– My Oracle Support Note 361323.1

Instance Caging - limit the amount of CPU used by an Oracle instance

Database Resource Manager - allocate CPU resources across multiple

services that share the same database

I/O Resource Manager - allocate I/O bandwidth among databases

– IORM is unique to Exadata storage

– Improve OLTP latencies

Latest resource management best practices refer to MOS note

1339769.1

Reliable Service & Optimal Performance in Consolidated Environments


Essential Exadata Operational Practices Goal: Maximum Stability and Availability

1. Exachk 2. Monitor 4. Patch 3. Testing Operations


Use Exadata HealthCheck (Exachk) Regularly Contains Critical Alerts and MAA configuration checks

Exachk

Hardware, Software and MAA

checks

Validated Exadata MAA

configuration best practices

MAA score card and review

Critical software and patch updates

Pre/Post 11.2.0.3 upgrade checks

Support for V2, X2, and X3 Exadata

families

MOS 1070954.1

When to run?

• After initial Oracle Database Machine

deployment

• During times of least load on system

• Pre and post planned maintenance

• Grid Infrastructure and at least one database

up and running

• At least every three months as part of

regular operational procedures


Enterprise Manager 12c Exadata Monitoring

Integrated view of HW and SW

Hardware view

– Schematic of cells, compute

nodes and switches

– Hardware components alerts

Software and System views:

– Performance, availability, usage

by databases, services, clusters

– Software alerts db, cluster, ASM

– Topology view of database

systems/clusters

‘exachk’ plug-in

Exadata as Grid Control Target


Testing: Best Protection is a Strong Defense

Essential Test Requirements

and Goals – Performance, HA and growth

requirements understood

– Test and prove changes

– Application functionality,

behavior and impact understood

– Validate repair and recovery

– Backout plans desired

Testing reduces risk and uncertainty

Essential Test Resources (in order of preference)

– Dedicated Exadata system

identical to production

– Smaller Exadata system or

Data Guard standby

– Non-Exadata system

Validate

Change

1. Real App

Testing/Clone Test

DB

2. Upgrade or

Patch with

Essential Test Approach – Know upgrades work

– Validate, automate, practice

– Use MAA outage matrix

– Execute Data Guard role

transitions

SW EBS Footprint

Three Regional EBS Application Environments

US/Canada (R12.1.3) HR, Benefits (Global Employees Management Systems)

Financials (AP,GL, FA) ; Property Management; EAM

Latin America (R12.1.3)

Asia Pacific (R12.1.3)

Financials (AP,AR,GL, FA)

Supply Chain & Manufacturing (OM, OPM, WMS, ASCP)

SW Adoption of Engineered Systems Where we started . . . .

Challenges (US/Canada EBS Env.)-

- Complexity of using Veritas Clusterware with Solaris

- Concurrent Tier on DB Servers

- Long cloning time (24 hours) & backup time (12 hours)

- Poor performance of several business processes

- Apps Upgrade to R12 very slow on old hardware

SW Adoption of Engineered Systems Where we started . . . .

Objective – Replace Hardware along with Apps Upgrade from11i to R12

• POV of Exadata at OSC with SW actual EBS data & configuration

• Evaluated Sun M5000, Dell R910 & Exadata X2-2 in Q4 2010 for our

US/Canada EBS Environment

Key Decision Points

- Speed to market - Performance

- Stability and Manageability with Engineered Architecture

- Single vendor for support

• Acquired Two Exadata machines(X2-2 ¼ & X2-2 ½ ) in May 2011

• Faster delivery to meet business needs

-Fully configured clustered hardware in 2 weeks

• Direct performance benefit in R12 upgrade cycle; Upgrade time

reduced from ~ 200 hours (old H/W) to 65 hours (including Database

platform migration to Exadata)

• Managed the Application upgrade to R12 in 36 hours, by handling

Database Platform migration ahead of schedule

Benefits

• Key business processes performance increased significantly

Depreciation of 1M+ assets

Before: 20-24 hours execution time serially

After: 4-5 hours execution time in parallel

• Direct benefit to the business with significant improvements in the

month-end processes

• Reduced backup and clones dramatically

Before: ~12 hours to perform backup and restore of 1 TB DB

After: <60 minutes to perform backup and restore of 2 TB DB

EBS Cloning time reduced to 6 hours from 24 hours

Benefits (continued)

Architecture Highly Available based on MAA Guidelines

SW Second Exadata Implementation Objective – Add capacity to Latin America EBS environment for EBS

implementation in Argentina and Brazil. And add capacity for OBIEE

environment.

Additional Benefits –

- Comprehensive Patching – Single application testing cycle

- Significant performance improvements in Demantra & ASCP planning jobs - Demantra weekend forecasting process time reduced to < 6 hours from 33

hours

- Performance improvement in various manufacturing & shipping processes

- ASR - Created SR automatically & SW being notified for HW replacement

- Reallocate resources to higher value-add activities

Performance Improvements for OBIEE – - ETL - Avg. 2X - 4X improvements

- Reporting - Avg. 4X - 10X improvements

Consolidation Platform for Stores Custom Application - Acquired Two Exadata machines (X2-2 ½ rack) in May 2012

- Database consolidated for key stores POS & AR applications

- Other Database consolidation is underway

Current Exadata Footprint

- One X2-2 ¼ Rack (HP – High Performance HDD)

- Two X2-2 ½ Rack (HP)

- Three X2-2 ½ Rack (HC – High Capacity HDD)

Architecture Shared DR

Lessons Learned - Need to develop strategy for managing Exadata between

DBA, Unix, Network & Storage team. Who has root?

- ¼ rack, too much space lost for fault tolerance

- Do not use Exadata Admin subnet for AppsTier, SW specific

- Leverage 10G interface for cloning / backup (if possible)

- Understand implications of multiple Networks on host, this

was new to SW

- EM Cloud Control 12c for monitoring

- Periodically run and review Exachk

Platinum Services • Joined early adopter program – June 2012

• Platinum Services and ACS resources performed implementation

• Immediate access to Platinum Services and Oracle Support

resources to resolve issues

• Benefit to SW – Saved time ($$) and reduced risk

• Lessons Learned -

– Plan Early

- Demand on Oracle resources is high - Schedule is a challenge

– Manage the vendor

- Review Upgrade Plans - Monitor Access to Systems

– Identify ways to minimize impact/downtime

– Minor Issues encountered unique to SW Network

Our Vision - Next Steps

• Exadata - Primary DB platform for applications requiring highest

availability and performance (both OLTP and Decision Support)

• ZFS Backup Appliance – Implementation is underway for DB disk

backups; replacing NetApp. Using 10G N/W, move to IB in future

• Exalogic – POV completed; very encouraging results for ERP, ASCP &

Demantra processes

• Strategy is to move to complete Engineered Platform for ERP

• Planning, Demantra, OBIEE and critical Java/WebLogic Applications

• Provision and Migrate AsiaPac EBS to Exadata / Exalogic platform

• Using Exadata with 12c multitenant(pluggable) for non-EBS Databases
