The current DayTrader runtime configuration is
detailed below. View and optionally update run-time parameters.
NOTE: Parameters settings will return to default
on server restart. To make configuration settings persistent
across application server stop/starts, edit the servlet init
parameters for each DayTrader servlet. This is described in the DayTrader FAQ.
|
| Run-Time Mode
<%String configParm = "RunTimeMode";
String names[] = TradeConfig.runTimeModeNames;
int index = TradeConfig.runTimeMode;
for (int i = 0; i < names.length; i++) {
out.print(
" " + names[i] + "
");
}
%>
|
Run Time Mode determines server implementation of the TradeServices
to use in the DayTrader application Enterprise Java Beans including
Session, Entity and Message beans or Direct mode which uses direct
database and JMS access. See DayTrader
FAQ for details.
|
| JPA Layer
<%configParm = "JPALayer";
names = TradeConfig.jpaLayerNames;
index = TradeConfig.jpaLayer;
for (int i = 0; i < names.length; i++) {
out.print(
" " + names[i] + "
");
}
%>
|
JPA Layer determines what kind of JPA Implementation Daytrader
EJB classes use. Typically, Apache Geronimo uses OpenJPA, and RedHat
JBoss 5 uses Hibernate.
|
| Order-Processing Mode
<%configParm = "OrderProcessingMode";
names = TradeConfig.orderProcessingModeNames;
index = TradeConfig.orderProcessingMode;
for (int i = 0; i < names.length; i++) {
out.print(
" " + names[i] + "
");
}
%>
|
Order Processing Mode determines the mode for completing stock
purchase and sell operations. Synchronous mode completes the order
immediately. Asychronous_2-Phase performs a 2-phase commit over the EJB Entity/DB
and MDB/JMS transactions. See DayTrader
FAQ for details.
|
| Scenario Workload Mix
<%configParm = "WorkloadMix";
names = TradeConfig.workloadMixNames;
index = TradeConfig.workloadMix;
for (int i = 0; i < names.length; i++) {
out.print(
" " + names[i] + "
");
}
%>
|
This setting determines the runtime workload mix of DayTrader
operations when driving the benchmark through TradeScenarioServlet.
See DayTrader FAQ for details. |
| WebInterface
<%configParm = "WebInterface";
names = TradeConfig.webInterfaceNames;
index = TradeConfig.webInterface;
for (int i = 0; i < names.length; i++) {
out.print(
" " + names[i] + "
");
}
%>
|
This setting determines the Web interface technology used, JSPs
or JSPs with static images and GIFs. |
