Hi Alan,

Yeah.

Each thread has:
1 session
1 transaction
1 connection
and a bunch of tables

Each thread's runtime object creation code is as follows:

TIB_Session * tmpSession = new TIB_Session(this);
TIB_Connection * tmpDatabase = new TIB_Connection(this);
tmpSession->DefaultConnection = tmpDatabase;
tmpDatabase->IB_Session = tmpSession;
TIB_Transaction * tmpTransaction = new TIB_Transaction(this);
tmpTransaction->IB_Session = tmpSession;
tmpTransaction->IB_Connection = tmpDatabase;
tmpDatabase->DefaultTransaction = tmpTransaction;
tmpDatabase->DefaultTransaction->Isolation = tiCommitted;

tmpDatabase->LoginPrompt = false;
tmpDatabase->Protocol = cpTCP_IP;
tmpDatabase->Username = "SYSDBA";
tmpDatabase->Password = "masterkey";
tmpDatabase->Connected = true;

Thanks Alan.
