09:12 - What is the difference between using it in real-time and offline?
11:09 - How do I get this “mdb” file to analyze?
12:00 - Could you provide some insight in what direction will be with CHA and MGMT DB on Exadata environments?
13:20 - Can you walk through a typical use scenario of CHAG?
19:00 - You mention “predicted values” for each metric. Can I see what these are?
23:18 - Is the predicted time based upon historic data of the system itself? Are there any hard ranges on top of this?
24:33 - What with systems that gradually start getting higher wait events?
26:56 - What are some other scenarios that CHAG is useful fo?
31:13 - How can I tell which Problems were happening most frequently?

39:00 - Does this tool require the GIMR to be deployed?
40:18 - What happens now that the GIMR is optional?
43:37 - There is another CHA tool called CHA Finding Explorer. How do they compare?
45:00 - Can CHAFE and CHAG work together?
46:00 - Is it necessary to run the CHA at server side or we can run this at a client machine?
