DayTrader is benchmark application built around the paradigm of an online stock trading system. Originally developed by IBM as the Trade Performance Benchmark Sample, DayTrader was donated to the Apache Geronimo community in 2005. This application allows users to login, view their portfolio, lookup stock quotes, and buy or sell stock shares. With the aid of a Web-based load driver such as Mercury LoadRunner, Rational Performance Tester, or Apache JMeter, the real-world workload provided by DayTrader can be used to measure and compare the performance of Java Platform, Enterprise Edition (Java EE) application servers offered by a variety of vendors.

Application Architecture

DayTrader is built on a core set of Java EE technologies that includes Java Servlets and JavaServer Pages (JSPs) for the presentation layer and Java database connectivity (JDBC), Java Message Service (JMS), Enterprise JavaBeans (EJBs) and Message-Driven Beans (MDBs) for the back-end business logic and persistence layer. The following diagram provides a high-level overview of the full workload application architecture.

• Start Geronimo by running the following command:
  <geronimo_home>/bin/geronimo start
  
• The provided database creation script requires setting the GERONIMO_HOME environment variable. On the same window you start Geronimo run the following command:
  set GERONIMO_HOME=<geronimo_home>
  
• Change directory to the directory containing the database creation scripts.
  cd <daytrader_home>/bin/dbscripts/derby
  
• Open createDerbyDB script and verify/modify the Derby version to match the one being used by Geronimo ( e.g. <geronimo_home>/repository/org/apache/derby/derby/10.2.2.0 ). Once you verified the versions match run the script.
  createDerbyDB
  You sould see a scree similar to the one illustrated below.

• You can verify the database was created by pointing your browser to the Geronimo Administration Console and clicking on DB Manager.
• The last step in this configuration is to update the deployment plan. Edit the daytrader-g-2.0-SNAPSHOT-plan.xml deployment plan located in the <daytrader_home>\plans directory and replace ge-activemq-rar/1.2-beta/rar with ge-activemq-rar/1.2/rar.
