</property>
<property name="username" value="xxxxxx" />
<property name="password" value="yyyyyyy" />
<property name="connectionProperties" value="v$session.program=LvTest" />
<property name="maxTotal" value="100" />
<property name="maxIdle" value="-1" />
<property name="minIdle" value="5" />

the count of queryresult increase to 20 rapidly at the begining of the test ,
After 60 seconds count will change to 0 Suddenly
