java.lang.Object
   org.apache.ojb.performance.PerfMain

PerfMain
public class PerfMain (Code)
The OJB stress/performance test - a simple performance test application to run O/R mapper in a simulated single/multi-threaded environment.

You have two possibilities to run this test:

- use the OJB build script and call
ant perf-test

- or for standalone use perform the test class by yourself
java -classpath CLASSPATH org.apache.ojb.performance.PerfMain
[comma separated list of PerfTest implementation classes, no blanks!]
[number of test loops, default '5']
[number of threads, default '10']
[number of insert/fetch/delete loops per thread, default '100']
[boolean - run in stress mode if set true, run in performance mode if set false, default 'false']
[boolean - if 'true' all log messages will be print, else only a test summary, default 'true']

For example:

java -classpath CLASSPATH my.MyPerfTest,myMyPerfTest2 3 10 200 false true
