This is just a modified question:

I have exported the full db to new instance.
the user tablespace containing all tables has min_extent as 128k. all tables now have just one extent.

But the initial and next are not same for many tables.
Initial extents are different for different catagories of table as mentioned earlier.

Should I make initial and next same and pct_inc as zero to avoid table fragmentation in future?

' tables having different initial/next ln same ts '-->is it ok?

thanks
