table extents in what chunks?

Hi! In my efforts to "eliminate extent interleaving" I came about to study the distribution of table extents among dbspace chunks. For a specific table I want to know in what chunks it's extents are located. (I can do a "oncheck -pe | more" and look through the output but I want to query the SMI-tables instead). Any ideas about such a sql-query? What I then want to do is a "ALTER INDEX TO CLUSTER" on a table (described in INFORMIX-Online Dynamic Server, Administrator's Guide, Volume 1 Version 7.1", page 15-23) to rebuild the table with _one_ extent only. My focus on chunks is because of the following lines in the Guide: "The chunk must contain adequate contiguos space in which to rebuild the table". But what if the table has extents in many chunks? Does anybody have experience in doing such a rebuild of a table? Sent via Deja.com http://www.deja.com/ Before you buy.
