[jboss-user] [JCA/JBoss] - inactive connections are not closed in oracle even i mentine

[ps.ganesh]

I am using a pooled connection in my web application using jboss specific configuration file oracle-ds.xml the entries of the file is :

<local-tx-datasource>
      <jndi-name>OracleDS-QA</jndi-name>
        <connection-url>jdbc:oracle:thin:@opi049.nod.comp.com:1551:prodqa</connection-url>
        <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
        <user-name>xxx</user-name>
        123
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleExceptionSorter</exception-sorter-class-name>
      <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.OracleValidConnectionChecker</valid-connection-checker-class-name>
      <new-connection-sql>select 1 from dual</new-connection-sql>
      <check-valid-connection-sql>select 1 from dual</check-valid-connection-sql>
<min-pool-size>10</min-pool-size>
      <max-pool-size>100</max-pool-size>
      <idle-timeout-minutes>1</idle-timeout-minutes>
      
      <type-mapping>Oracle8i</type-mapping>
      
</local-tx-datasource>

In my application I am getting the connection by datasource as :

Context ctx=new InitialContext();
ds = (DataSource) ctx.lookup(jndiName);
..
ds.getConnection();

When I complete load testing with 50 users I found 50 inactive connections at oracle side 

[ SELECT COUNT(*) FROM v$session WHERE osuser='tsering' AND status='INACTIVE' ]

and when i complete single transation after that my inactive conn incremented by 1.
I am not aware why the inactive connections are there at oracle side. Is there any mechanism to remove these inactive connections from oracle side.

I know that when we call con.close() method in a pooled connection the connection is returned back to pool but I didn't know why it is not using the inactive connection for a new connection request  it is creating a new one.
