But you would only want to sum them if they are adjacent. Suggestions on how?

I am having a problem though when Oracle is breaking the datafile into multiple free extents, i.e. 26 107,758 153,816 ***FREE*** 426 126,985 507,904 ***FREE*** 426 190,473 421,824 ***FREE*** 427 9 507,904 ***FREE*** 427 63,497 507,904 ***FREE*** 427 126,985 507,904 ***FREE*** 427 190,473 421,824 ***FREE*** File 427 is a brand new 1900M datafile in the tablespace. Right now I am seeing the largest free as 507,904 bytes and not 1900 M. Any suggestions on how to combine the extents in the sql script.
