OCCI env- createConnection error

Question

Good day. hlp plz.
Can't solve the problem.
on conn = env->createConnection(username, password, db) got exception ORA-32102:Invalid OCI handle.
Have a code:
     try
          env = Environment::createEnvironment (Environment::OBJECT);
          conn = env->createConnection(username, password, db);
     env->terminateConnection (conn);
          Environment::terminateEnvironment (env);
     catch(SQLException& e)
          cout<<e.what()<<endl;
username = test, pass = XXX, db = testdb
in tnsnames.ora alias testdb exists
and command sqlplus test/XXX@testdb executes successfull;
what i did wrong?

VS2005
oracle 9i (oraocci9.lib)
tns
testdb =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.1.1)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = WORK)
Environment created successfully, connection not.
if trying type username = TEST, instead of test then got Unhandled exception which can't handle even via catch(...){cout<<"Oops";}
