Performance and Scalability

We have tested several E-Business Suite workloads on

Exadata to develop our tuning best practices, including:

Workloads from Oracles 18 TB internal E-Business Suite

Im lementation known as Global Sin le Instance GSI

Workloads from Oracles E-Business Suite 12.1.2 benchmark

(OASB), namely:

Payroll

Online

Our findings are documented in a technical white paper See http://www.oracle.com/goto/maa

We continue to test and tune and u date the a er re ularl

This is still E-Business Suite running on Oracle Database

Nothing much changes in the application

Everything you already know still applies

We dont lose anything with Exadata, but there is lots to

be ained

21/33


All workloads are characterized by high DB CPU

utilization

Benefit greatly from the fast Exadata processors

High Exadata Smart Flash Cache hit rates

Average IO latency reduced by 58 percent (v. Exadata with Flash

Cache disabled

Automatic no special tuning required

Data intensive batch work benefits from the high IO

request rates and throughput

High IO capacity also benefits other activities:

Compression has been found to save space and improve

performance for most EBS workloads

Support Note 1110648.1 - Oracle E-Business Suite Release 12.1

with Oracle Database 11 Advanced Com ression

Compression can significantly reduce RMAN databasebackup size, for example for GSI

18 TB data files

3 TB compressed backup (low compression)

8.1 TB space saving

Recommendation: Place middle tier components on

separate servers

Performed well in our tests

Offers more flexibility
