Performance and ScalabilityOngoing TestingOngoing Testing

• We have tested several E-Business Suite workloads on Exadata to develop our tuning best practices, including:• Workloads from Oracle’s 18 TB internal E-Business Suite

Implementation, known as Global Single Instance (GSI)Implementation, known as Global Single Instance (GSI)• Workloads from Oracle’s E-Business Suite 12.1.2 benchmark

(OASB), namely:• Order to Cash• Order to Cash• 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 update the paper regularly

19

We continue to test and tune and update the paper regularly

Performance and Scalability Findings OverallFindings – Overall

• This is still E-Business Suite running on Oracle Databaseg• Nothing much changes in the application• Everything you already know still applies

• We don’t lose anything with Exadata, but there is lots to be gained…g

20

Performance and Scalability Findings High CPU UtilizationFindings – High CPU Utilization

• All workloads are characterized by high DB CPU y gutilization• Benefit greatly from the fast Exadata processors• Will likely have spare capacity to facilitate growth or consolidation• Will likely have spare capacity to facilitate growth or consolidation

21

Performance and Scalability Findings High Memory UtilizationFindings – High Memory Utilization

• Workloads benefit from large SGA and PGA made gpossible by large Exadata memory capacity• Allow larger PGA for high concurrency online workloads• Configure hugepages for the SGA• Configure hugepages for the SGA

• See Support Note 744769.1 - How to Configure HugePages for Oracle Database on 64-bit Linux Platforms

No need to allow for large Linux file system cache• No need to allow for large Linux file system cache

22

Performance and Scalability Findings Exadata Smart Flash CacheFindings – Exadata Smart Flash Cache

• High Exadata Smart Flash Cache hit ratesg• 61% Hit Rate in Order to Cash tests• Average IO latency reduced by 58 percent (v. Exadata with Flash

Cache disabled)Cache disabled)• Automatic – no special tuning required

23

Performance and Scalability Findings Disk IOFindings – Disk IO

• Data intensive batch work benefits from the high IO grequest rates and throughput

• High IO capacity also benefits other activities:B k t 13TB h i f ll k t t i t l• Backups – up to 13TB per hour in full rack tests – incremental backups are faster still

• Flashback database

24

Performance and Scalability Findings CompressionFindings – Compression

• 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 11g Advanced Compressionwith Oracle Database 11g Advanced Compression

• Compression can significantly reduce RMAN database backup size, for example for GSI• 18 TB data files• 11.1 TB conventional backup (with unused block compression)11.1 TB conventional backup (with unused block compression)• 3 TB compressed backup (low compression)• 8.1 TB space saving

25

Performance and Scalability Middle Tier PlacementMiddle Tier Placement

• Recommendation: Place middle tier components on separate servers• Performed well in our tests• Leaves more power for database processing• Leaves more power for database processing• Offers more flexibility

26

Performance and Scalability Best Practice TakeawaysBest Practice Takeaways

• E-Business Suite runs well on Exadata.

• We recommend implementing the following best practices:• Configure Hugepages for more efficient memory usage• Implement Database Compression to save space and improve

performance

• Place middle tier components on separate servers

accounting for 3,000 users. 2. All Reports and batch jobs are run nightly to avoid

daytime contention, and month-end billing cycles prevent other access.

3. A significant amount of time is spent fighting fires, running ad-hoc queries against large data sets and optimizing
