Connection Pool configuration

[Propes, Barry L [GCG-NAOT]]

Hello, I'm dealing with Tomcat 4.0.1 and -4.1.3.
 
I badly need to get connection pooling configured, but am not quite sure how to 
do it.
 
Here's  a block from my server.xml file.
 
 
    <Realm  className="org.apache.catalina.realm.JDBCRealm" debug="99"
 driverName="oracle.jdbc.OracleDriver"
 connectionURL="jdbc:oracle:thin:@169.xxx.xx.xxx:1521:SID"
 connectionName="user_name"
 connectionPassword="user_pwd"
 userTable="users" userNameCol="user_name" userCredCol="user_pass"
 userRoleTable="user_roles" roleNameCol="role_name" />
 
 
This goes to the users table created for password sessions.
 
Do I configure anything here for Connection Pooling? Do I add 
maxActive        8      
minIdle 0 , etc.?
 
How would I alter or configure this? Any advice is welcomed. 
 
Thanks,
 
Barry
