I have read about rollback storage parameters in all kind of documentation
And I am not sure if MINEXTENTS should be 10,8,20 or x.
Could somebody explain why should be 10 or 20 and what is the impact if MINEXTENTS =2.
And if I don't ask to much
Is there a documentation that explain in depth how to interpret for example V$ROLLSTAT
It depends on your application. How big do your RBS need to be? What is your INITIAL and NEXT extent settings in the RBS tablespace? What is the relationship of your OPTIMAL RBS settings and your MINEXTENTS?
Personally, I like to have my minextents = the number of extents that will comprise my RBS when they are at their OPTIMAL size.
