DB2 FOR LUW / DB2FORLUW / A10 - DB2

db2 inspect may falsely report the following problem in the 
formatted inspect file: 
 
       Error: Space Map Page invalid page states for extent at 
location <NNNN> in the space map page, extent contains used and 
not exist pages. 
 
This can happen if you have issued a REORG INDEX(ES) with the 
RECLAIM EXTENTS option.  If the RECLAIM EXTENTS reclaimed a full 
extent right at the end of an index SMP page (ie the next SMP 
page is the first page of a new extent), or reclaimed the very 
last extent in the index object, then db2inspect incorrectly 
thinks that these 'Not Exist' pages exist in the same extent as 
used pages and it reports the error. 
 
There is in fact nothing wrong with the index object.  However, 
if you see this message, db2support should be engaged to ensure 
that you indeed have a false alarm.
