3 Questions & Answers – Q & A
| 1 | Bufferpool usage
Is it exact, down to the getpage per object? |
Not really as we are WLX workload based so it is per/sql no per/object but as an overview and starting point it is pretty good |
| 2 | PKLIST Chains
What type of performance boost can I expect? |
It Depends. According to the Bank of China performance presentation quite a lot! |
| 3 | SQL Time Travel
Can I export the data and send to colleagues or use cognos to access the data? |
Yes indeed and as the SQL is externalized you should be able to plug it into cognos etc. |
