Class DriverUtility

java.lang.Object

org.apache.derbyTesting.system.oe.run.DriverUtility

public class DriverUtility
extends java.lang.Object

Driver to do the load phase for the Order Entry benchmark. This class takes in following arguments currently: Usage: java org.apache.derbyTesting.system.oe.run.DriverUtility options Options:

1. -scale warehouse scaling factor. Takes a short value. If not specified defaults to 1
2. -doChecks check consistency of data, takes a boolean value. If not specified, defaults to true
3. -driver jdbc driver class to use
4. -dbUrl database connection url
5. -help prints usage

To load database with scale of 2 and to not do any checks, the command to run the test is as follows:
java org.apache.derbyTesting.system.oe.run.DriverUtility -driver org.apache.derby.jdbc.ClientDriver -dbUrl 'jdbc:derby://localhost:1527/db' -scale 2 -doChecks false
