set parallel threads python script error

Hi all:

I set parallel threads python script, run script error: Follow is python script:

test1 = Test(1, "Database insert")

test2 = Test(2, "Database query")

# Load the Oracle JDBC driver.
DriverManager.registerDriver(OracleDriver())

def getConnection():
    return DriverManager.getConnection(
        "jdbc:oracle:thin:@uapgv4102.us.oracle.com:1521:XE", "grinder", "grinder")

def ensureClosed(object):
    try: object.close()
    except: pass

# One time initialisation that cleans out old data.
connection = getConnection()
statement = connection.createStatement()

try: statement.execute("drop table grinder_test1126")
except: pass

statement.execute("create table grinder_test1126(thread number, run number)")

ensureClosed(statement)
ensureClosed(connection)

class TestRunner:
  def __init__(self):
        tid = grinder.threadNumber

        if (grinder.threadNumber % 2 == 0):
             Even threadNumber
             Do insertStatement
        else:
             Odd threadNumber
             Do queryStatement

        endTime = datetime.now() + duration
        notDone = True
        while notDone:
         connection = None
         insertStatement = None
         queryStatement = None
         notDone = datetime.now() < endTime

        try:
            connection = getConnection()
            insertStatement = connection.createStatement()
            queryStatement = connection.createStatement()

            test1.record(insertStatement)
            insertStatement.execute("insert into grinder_test1126 values(%d, %d)" %
                                    (grinder.threadNumber, grinder.runNumber))

                                   grinder.threadNumber)

        finally:
            ensureClosed(insertStatement)
            ensureClosed(queryStatement)
            ensureClosed(connection)
