At FDD'2010 Dmitry Kuzmenko has presented 2 presentations - the is one about approach to maintain big databases (50-400Gb) in the right way and the second is about restore speed tests.
Among other thing Dmitry said that any participant who will send email request to dataguard at ib-aid.com till 20-JUL-2010, will get this tool's 1 year license for free.
We just finished to process 108 requests and sent them all (check antispam folder if you did not get it).
So, it is interesting to see that approximately 20% of attendees can think about right database maintenance and how to avoid corruption. Other 80% are welcome to our recovery service.
