Can not create the connection in the enrironment!!

Question

hello,every one:
please see the following code:
          Environment *env = Environment::createEnvironment(Environment::OBJECT);
          Connection *conn = env->createConnection(userName,password,connectString);
try
//use the conn
          catch (SQLException &ex)
               env->terminateConnection(conn);
               Environment::terminateEnvironment(env);
               throw;//re-throw
          env->terminateConnection(conn);
          Environment::terminateEnvironment(env);
          Environment *ev = Environment::createEnvironment(Environment::OBJECT);
//the program stopped here,display i can not create the new connection
          Connection *cn = ev->createConnection(userName,password,connectString);
          ev->terminateConnection(cn);
          Environment::terminateEnvironment(ev);
I have terminated the connection and the environment,then why I can not create the
connection in the new environment?
I have tried several times,if you connect the same database as the former,then it
does not work,but if you connect a new database ,it can create the new connection!
plus:I don't want to use conection pool .
Can I have some method to solve the problem?
Please help me!
Thanks a lot in advance!

Hi Tony,
This similar sample works perfectly fine for me. Can you
retry with this?
#include <iostream>
#include <occi.h>
using namespace std;
using namespace oracle::occi;
int main()
        Environment *env = Environment::createEnvironment(Environment::OBJECT);
        Connection *conn = env->createConnection("scott","tiger","inst1");
        try
        //use the conn
        catch (SQLException &ex)
                env->terminateConnection(conn);
                Environment::terminateEnvironment(env);
                cout<<ex.getMessage();
        env->terminateConnection(conn);
        Environment::terminateEnvironment(env);
        Connection *cn;
        Environment *ev;
        try{
        ev = Environment::createEnvironment(Environment::OBJECT);
        cn = ev->createConnection("scott","tiger","inst1");
        catch (SQLException &ex)
                ev->terminateConnection(cn);
                Environment::terminateEnvironment(ev);
                cout<<ex.getMessage();
        ev->terminateConnection(cn);
        Environment::terminateEnvironment(ev);
}Rgds
