Well, 9.2.0.1 changes the outcome: you really need 9.2.0.6 to have at least a chance of having a good patch level. As well if the install is a default install, the redo log files will be exceedingly small: they need to be at least 100Mb each. Otherwise the checkpoints (one every log switch) will be killing you.
