4 Executive summary In May 2008, Oracle officially announced support for Application Server 6.1 with JD Edwards EnterpriseOne software on IBM Power Systems platform with IBM i. 6.1 uses a Java implementation called IBM Technology for Java (IT4J) which is based on the same technology that IBM uses on other system platforms. IT4J provides a 32-bit implementation which can offer both performance improvements and reduced memory requirements for many applications. Customers now have a choice to run either 6.0 Classic 64-bit or 6.1 IT4J 32-bit with JD Edwards EnterpriseOne software. The IBM Oracle International Competency Center (ICC) executed tests to compare the performance of 6.1 with 6.0 in a JD Edwards EnterpriseOne 8.12 environment on an IBM Power Systems platform with i. The tests, utilizing Oracle s robust Day in the Life (DIL) kit for web users, clearly showed the benefits of upgrading to 6.1: 6.1 required up to 66% less memory than 6.0 while using up to 26% less CPU, and achieved up to 11% faster response time. Introduction To characterize the performance of 6.0 running JD Edwards EnterpriseOne software, the ICC first ran tests establishing recommended sizing guidelines and validating balanced performance across CPU, memory and disk. These tests were then repeated after switching to 6.1 to analyze its performance and memory utilization for comparison. An advantage of testing with Oracle s DIL kit is that its 17 test scripts exercise representative transactions of the most popular JD Edwards EnterpriseOne applications including Supply Chain Management, Supplier Relationship Management, Human Capital Management, Customer Relationship Management, and Financial Management. Also, this complex mixture of applications includes Advanced Pricing, Verity and Vertex to more closely reflect customer environments. Test environment A Power Systems p5-570 three-way server running i was set up for the tests as an All-on-i configuration, meaning it ran all three JD Edwards EnterpriseOne application components: the JD Edwards EnterpriseOne application server the Web tier consisting of, JD Edwards EnterpriseOne HTML, and IBM HTTP servers and the database server. 2

5 JD Edwards EnterpriseOne was configured with fifteen users per call object kernel. Memory was allocated into four memory pools in order to focus on and measure utilization of the web tier : *machine *base for the database functions (QSQSRVR jobs) *shrpool1 for JD Edwards EnterpriseOne server jobs *shrpool2 for the web tier. For the three different user counts of 100, 200 and 300 web users, all tests were run with JD Edwards EnterpriseOne HTML server configured as a single JVM. The white paper - IBM System i Performance and Tuning Tips for Oracle s JD Edwards EnterpriseOne 8.12, 6.0, and 6.1 was followed for the initial settings. Initial heap size for 6.0 was established at 1.5 MB of memory per user and *NOMAX was used for the maximum heap size. For 6.1 the initial heap was set to 436 MB of memory and the maximum heap was set to 1,744 MB memory. The size of the memory pool for 6.0 was also established based on the white paper. For 6.1 the size of the memory pool was rounded up from the maximum heap to 2 GB memory. A free tool new to the System i, IBM Support Assistant (ISA), was used to analyze maximum heap size and garbage collection activity for the 6.1 IT4J environment. The Power Systems server was up-to-date with the latest InfoAPAR list of IBM-recommended fixes. For IBM links to the white paper, the ISA tool, and the InfoAPAR please see Appendix B. The specifications for the Power Systems hardware used for the tests are listed in Table 3 and the software levels used are listed in Table 4 in Appendix A. Test results comparing 6.0 and 6.1 As shown in Table 1, the three different tested user counts are listed with performance metrics for 6.0 runs followed by 6.1 runs. Total web user average response time is followed by the memory allocated for the web tier memory pool, and then the percent of CPU utilized by the web tier. Also listed is the percent improvement realized by the 6.1 tests for memory and CPU. As the user count increases, the reduction in 6.1 s memory utilization improves also. For 100 users, response time with 6.1 was 3% faster while it used 33% less memory and improved CPU utilization by 33%. With 200 users, response time improved by 17% and CPU utilization improved by 23%, all while 6.1 used 50% less memory. The 300 user tests achieved 11% improvement in response time while using 26% less CPU, with 6.1 only using 2 GB memory as compared with 6 GB memory for 6.0, a 66% reduction in memory. The non-database page faults per second in the web tier memory pool remained at two or lower during all of the 6.0 and 6.1 tests, indicating memory was sufficient. 3

7 Conclusions 6.1 outperformed 6.0 while running a JD Edwards EnterpriseOne web user workload using Oracle s DIL test kit by utilizing up to 66% less memory and consuming up to 26% less CPU while achieving up to 11% faster response time. Customer Notes While both IBM and Oracle encourage customers to upgrade to 6.1 to take advantage of these improvements, customers need to comply with Oracle s Minimum Technical Requirements (MTRs) for JD Edwards EnterpriseOne software when deciding between 6.0 and 6.1. The Oracle web site for the MTRs can be found in Appendix B. Since each customer s environment is unique, and an upgrade to 6.1 may also necessitate an upgrade to JD Edwards EnterpriseOne software, an official upgrade sizing estimate is highly recommended. A sizing estimate can be obtained by following the instructions in the sizing questionnaire available from the IBM Hardware Sizing Questionnaires web site listed in Appendix B. 5
