--------------------------------------------------------------
Connection Pool when connections are available in the pool still it creates new connections. We checked the database sessions only 5 sessions are active but in the connection pool there are 20 connections.


Environment Jboss 4.2.3 GA
Oracle 10g
no-tx-support - oracle-ds.xml

<datasources>
  <no-tx-datasource>
    <jndi-name>DSNAME</jndi-name>
    <connection-url>jdbc:oracle:thin:@HOST:1522:SERVICE_NAME</connection-url>
    <driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
    <user-name>USER</user-name>
    <password>PASS</password>
    <min-pool-size>1</min-pool-size>

        <new-connection-sql>select * from dual</new-connection-sql>
        <!-- sql to call on an existing pooled connection when it is obtained from pool - the OracleValidConnectionChecker is prefered -->
        <check-valid-connection-sql>select * from dual</check-valid-connection-sql>
