Thread DataSources & Database getConnection timeout error

Question

I'm usig pool connections in the application for database access.
At the moment i have max number of pool connections set to 1.
I'm using Oracle JDBC driver 10.2.0.1.0 and Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production With the Partitioning option JServer Release 9.2.0.5.0 - Production.
Running JRE/SDK 1.4.2
WAS6, Rational 6.0.0
I'm trying to get the connection inside a thread but I get this exception:
J2CA0045E: The connection is not available when you invoke the method createOrWaitForConnection for the resource jdbc/DBDS
and then this: Connection not available, Timed out waiting for 10000
The function in the main class is like:
PrT cnxT=new PrT(); Thread hilo=new Thread(cnxT, "cnxT"); hilo.start();
the runnable class is like:
public class PrT implements Runnable { public PrT(){ super(); } public void run(){ try{ InitialContext ic = new InitialContext(); DataSource ds = (DataSource) ic.lookup("jdbc/DBDS"); Connection con=ds.getConnection(); /** here my sql sentences **/ con.close(); } catch(Exception e){ } } }
If I change the max number of pool connections to 2 this executes pretty well and if I change the code and make the connection outside the runnable class there's no problem. But I need to make a new connection inside the runnable class because I'm gonna run multiple threads at once.
Why do I need to put the max connections pool in 2 if there're not connections opened?
What should I do to open the connection inside the thread?
Sorry for my english, is not my native language.
I'll appreciate any help.
Thanks.
