I think this one is a DB2 question.
My goal is to get an veray small number of extent for a db2 vsam.
So i read this topic :
https://www.ibm.com/support/knowledgece ... space.html
and i well anderstand, it is written db2 can caclulate itself the secondary space by using the dataclass parameters : "Extent Constaint Removal"
Am i right (DB2 Admin has never used this parameter in our company) so i'm asking if someone has ever used it ?
