When an application and/or process has completed operations with the database, it must release resources by closing the open files and disconnecting from the database engine.
Below is the code for Done():
//
// Done()
//
// This function handles the housekeeping of closing, freeing,
// disconnecting and logging out of the database
//
static void Done() throws IOException {
System.out.println("DONE");
try {
// close tables
System.out.println("\tClose tables...");
tableCustMast.Close();
tableCustOrdr.Close();
tableOrdrItem.Close();
tableItemMast.Close();
// logout
System.out.println("\tLogout...");
MySession.Logoff();
} catch (CTException E) {
Handle_Exception(E);
}
}
