Hello Doc. Been busy - big changes here. Takeover - new data centres ... busy boy. Anyway - I'm back now.

If I can prove that the software can't cope with transferring the data in the buffer cache then it'll kill this project (which is good!) and we can move onto RAC or whatever. But I have to be sure.

As its a cheap option management want it to work; as a DBA I want something reliable and supported by Oracle (which Double take is not).
