How to set min & max connections for MSSQLconnection pool

Question

Hi,
I want to set minconnection, maxconnection, idletimeout initial limit for the pool
I have got a MSSQL database connection using following java code.
// MSSQL DbConnection Code
import java.sql.*;
public class MsSqlDataSource
public static void main(String arr[])
Connection con = null;
ResultSet rs = null;
try{
com.microsoft.sqlserver.jdbc.SQLServerDataSource ds = new com.microsoft.sqlserver.jdbc.SQLServerDataSource();
ds.setServerName("10.50.50.51");
ds.setPortNumber(1711);
ds.setDatabaseName("test");
ds.setUser("starhome");
ds.setPassword("starhome");
con = ds.getConnection();
}catch(Exception e){}
}In oracle i have passed min and max number of connection properties through setConnectionCacheProperties method.
//Connection Pooling using Oracle Data Source:
m_connSource = new OracleDataSource();
m_connSource.setDriverType("thin");
m_connSource.setServerName(m_host);
m_connSource.setNetworkProtocol("tcp");
m_connSource.setDatabaseName(m_db);
m_connSource.setPortNumber(m_port);
m_connSource.setUser(m_user);
m_connSource.setPassword(m_password);
// Enable caching. m_connSource.setConnectionCachingEnabled(true);
java.util.Properties prop = new java.util.Properties();
prop.setProperty("MinLimit", m_minConnections);
prop.setProperty("MaxLimit", m_maxConnections);
prop.setProperty("InitialLimit", m_initialConnections);
prop.setProperty("InactivityTimeout", m_inactivityTimeout);
prop.setProperty("AbandonedConnectionTimeout", m_abandonedTimeout);
prop.setProperty("ConnectionWaitTimeout", m_connWaitTimeout);
m_connSource.setConnectionCacheProperties(prop);I dont know how to pass min and max number of connection properties for SQLServerDataSource. Is there any method available to pass min and max number of connection properties for SQLServerDataSource.
Iam using Tomcat. I found one way to set min and max connections for pool by doing changes in context.xml and web.xml using below url http://tomcat.apache.org/tomcat-4.1-doc/jndi-datasource-examples-howto.html
I dont want to touch tomcat configuration files. I need to set connection pooling properties which is independent of application server.
Please anybody give solution for this?
Thanks,
Prisha

Hi,
you need to define your database under the DB Admin tab. In the Schema objects node you'll find Sequence Implementations, and there you can definde min max values as well as caching and increments.
