Not to start an argument – but that doc we have posted is incorrect (not sure who did the updates). Also not sure who owns and needs to fix this, so copying
all the people who should address this.
Toad 9.1 and later supports Oracle 11g R1.
Toad 9.7 and later supports Oracle 11g R2.
Since 11g R2 is the only version Oracle generally supports (without extended support contract) – you need to be on
Toad 9.7 or greater.
