Application Server Data Source settings help needed (10.1.2.0.2)

Question

Hi,
Can someone tell me what maximum values can I set in the following properties under Connection Attributes when I define a DataSource on
Application Server. I have almost 25+ web application deployed on my 10.1.2.0.2 server that all uses one data source I have defined. Now the issue is the number of requests
are very high and every now and then I get timeout error when trying to get the database connection. At one particular instance at peak time I may get over 200+ requests that
do some databse connections etc. Following are my current settings. But need to increase some more but wondering what are the maximum values I can have. I have only one server 10.1.2.0.2
Connection Retry Interval (seconds) = 5
Max Connection Attempts = 3
Cached Connection Inactivity Timeout (seconds) = 30
Maximum Open Connections = 60
Minimum Open Connections = 10
Wait For Free Connection Timeout (seconds) = 15
What other properties can I have to make use of datasource effectively.
Thanks

Here is the copy of my datasources.xml.
<?xml version = '1.0' standalone = 'yes'?>
<!DOCTYPE data-sources PUBLIC "Orion data-sources" "http://xmlns.oracle.com/ias/dtds/data-sources-9_04.dtd">
<data-sources>
  <!--
            An example/default DataSource that uses
            Oracle JDBC-driver to create the connections.
            This tag creates all the needed kinds
            of data-sources, transactional, pooled and EJB-aware sources.
            The source generally used in application code is the "EJB"
            one - it provides transactional safety and connection
            pooling. Oracle thin driver could be used as well,
            like below.
            url="jdbc:oracle:thin:@host:port:sid"
       -->
  <data-source class="com.evermind.sql.DriverManagerDataSource" name="OracleDS"
               location="jdbc/OracleCoreDS" xa-location="jdbc/xa/OracleXADS"
               ejb-location="jdbc/OracleDS"
               connection-driver="oracle.jdbc.driver.OracleDriver"
               username="scott" password="tiger"
               url="jdbc:oracle:thin:@//localhost:1521/oracle.regress.rdbms.dev.us.oracle.com"
               inactivity-timeout="30"/>
  <!-- For SQL Server -->
  <data-source location="jdbc/TestDS"
               class="com.microsoft.jdbcx.sqlserver.SQLServerDataSource"
               password="pwd" xa-location="jdbc/TestDS"
               ejb-location="jdbc/TestDS"
               connection-driver="com.microsoft.jdbc.sqlserver.SQLServerDriver"
               username="usr"
               url="jdbc:microsoft:sqlserver://someloc99:1433/DevelopmentAp"
               inactivity-timeout="30" name="jdbc/TestDS"
               connection-retry-interval="5" max-connections="50"
               max-connect-attempts="3">
    <description>jdbc/TestDS</description>
    <property name="DatabaseName" value="DevelopmentAp"/>
    <property name="serverName" value="someloc99"/>
  </data-source>
</data-sources>I also tried changing max-connections="0" it did helped but still after sometime I get timeout while connecting to the database. Don't know if it's with SQL Server that is not letting that many concurrent connections/sessions or something on the Application Server side.
Thanks
