hi, list friends:

	I am interested in that topic:http://www.ioug.org/ioug_s/repository_pkg.doc?v_tech_content_dtl_phy_id=7666
	I am also considering whether too large rbs segment size does have adverse impact on database performance. In my production (OLTP) i configured rbs to be 1m*20 extents. But from v$rollstat and statspack, the average active size is 1.5M. I am considering whether it is too large and shrink it to 128k*20 will help.(but hard to find out the performance gains as it is a big system).
	If anyone in this list have IOUG membership, can you send me a copy? And i hope friends have experience on this topic can share your experience
