How to set Oracle's fixedString property in Orion Application Server?

I want to set the fixedString=true connection property for the Oracle JDBC driver in the datasource definition in Orion Application Server 2.0.7 (latest stable release).

I've tried the following but didn't work:

<data-source
    class="com.evermind.sql.DriverManagerDataSource"
    name="datasource_name" location="jdbc/datasource_location"
    connection-driver="oracle.jdbc.OracleDriver"
    开发者_运维知识库username="user" password="pass"
    url="jdbc:oracle:thin:@//database_host:1521/XE" >

    <property name="fixedString" value="true" />

</data-source>

Note: I've managed to set the property in Tomcat 6.0 this way (using the same Oracle JDBC driver, of course):

<Resource name="jdbc/datasource_name" auth="Container" type="javax.sql.DataSource"
    maxActive="100" maxIdle="30" maxWait="10000"
    username="user" password="pass" driverClassName="oracle.jdbc.OracleDriver"
    url="jdbc:oracle:thin:@//database_host:1521/XE"

    connectionProperties="fixedString=true;"

/>

But I need to set this in Orion. How can I do that?

It is a bug in the oracle application server you have to install OAS 10.1.2.3 has fix for that
