This is the reference for other benchmarks. author:    Thomas Mahler Constructor Summary public   PerformanceJdbcTest(String name)      BrokerTests constructor comment. Method Summary protected  void clearTable()      protected  void deleteArticles()      deletes all PerformanceArticle created by insertNewArticles. protected  void insertNewArticles()      create new PerformanceArticle objects and insert them into the RDBMS. public static  void main(String[] args)      launches the TestCase. protected  void readArticles()      read in all the PerformanceArticles from the RDBMS that have been inserted by insertNewArticles(). protected  void readArticlesByCursor()      read in all the PerformanceArticles from the RDBMS that have been inserted by insertNewArticles(). public  void testBenchmark()      protected  void updateExistingArticles()      updates all PerformanceArticles inserted by insertNewArticles(). Constructor Detail PerformanceJdbcTest public PerformanceJdbcTest(String name)(Code) BrokerTests constructor comment. Parameters:   name - java.lang.String Method Detail clearTable protected void clearTable() throws Exception(Code) deleteArticles protected void deleteArticles() throws Exception(Code) deletes all PerformanceArticle created by insertNewArticles. insertNewArticles protected void insertNewArticles() throws Exception(Code) create new PerformanceArticle objects and insert them into the RDBMS. The number of objects to create is defined by articleCount. main public static void main(String[] args)(Code) launches the TestCase. The number of Objects to work with and the number of iterations to be performed can be adjusted by setting them as commandline parameters. Parameters:   args - the String[] holding the commandline parameters. readArticles protected void readArticles() throws Exception(Code) read in all the PerformanceArticles from the RDBMS that have been inserted by insertNewArticles(). The lookup is done one by one, that is: a primary key based lookup is used. readArticlesByCursor protected void readArticlesByCursor() throws Exception(Code) read in all the PerformanceArticles from the RDBMS that have been inserted by insertNewArticles(). The lookup is done with a cursor fetch, that is: a between Statement is used to select all inserted PerformanceArticles and Objects are read in by fetching from the cursor (JDBC ResultSet). testBenchmark public void testBenchmark() throws Exception(Code) updateExistingArticles protected void updateExistingArticles() throws Exception(Code) updates all PerformanceArticles inserted by insertNewArticles(). All objects are modified and changes are written to the RDBMS with an UPDATE.
