You and I both know that you are a poser, admit it.Senior Oracle DBA
Anyone who can read English knows that a TPC benchmark is a fully reproduceable test of database performance.Do you actually know what the TPC benchmarks are?
Why do you hide behind a veil of total anonymity? What are you afraid that people will learn about your experience and training in Oracle?Why don't you stop spreading your misinformation?
Another myth. Got any evidence?You may get some advantages by changing your blocksize or including multiple blocksizes but it will be pretty minimal
Yikes, I missed that it was RAC, thanks!your top ten waits appear to be cluster/interconnect releated
Yes! Good point. There are millions of dollars of sales at stake in these benchmarks and the vendors spend a small forture testing and re-testing to get the fastest performance. Personally, I use the TPC benchmarks to find "hidden" kernel parms and other performance tricks. Why re-invent the wheel?TPC performance bench marks use all kind of wierd and wackey settings
Oops, my bad. That was a link on the benefits of a large blocksize, sorry. Here are my notes on multiple blocksizes:I think you linked to the wrong document
Yes, but it's not about the money.BTW, (and no offense meant) don't you think $250 worth of Tuning books (probably authored by yourself) is kinda little low a price?
Yes, in the hands of the inept, unqualified and reckless, I agree, they can be very hazardous.Your book is a hazard, not a help.
Just wanted to let you know that I appreciate your website and the services you >provide to the Oracle community. It seems that there has been a lot of Tom >bashing from Don and company for no good reasons.Just like you are bashing oracle forums with your websites, links and misleaded statements!
