I'm sorry you can't believe me.
But i don't have anymore the sysout of the job wiche have deleted the dataset but i 've just run an extract for example :
Command ===> Scroll ===> CSR
****** ***************************** Top of Data ******************************
000001 1- DFSMSHSM CONTROL DATASET - MIGRATED DATASET-- LISTING ----- AT 10:05:
000002
000003 DATASET NAME MIG LAST REF MIGRATED
000004 VOLUME DATE DATE
000005
000006 X.DEPT1.REPRISE 751904 17/11/15 18/01/22
000007 ENCRYPTION TYPE = ******* KEYLABEL = ****************************
000008 X.EM.SUPAA.ATTSXXX.DX7101Y 801191 07/10/30 07/12/10
000009 ENCRYPTION TYPE = ******* KEYLABEL = ****************************
000010 X.EM.SUAAR.ATTSXXX.DX7102Y 801191 07/10/30 07/12/10
000011 ENCRYPTION TYPE = ******* KEYLABEL = ****************************
and for example, the dataset : X.DEPT1.REPRISE
is not migrated and not on catalog because it was deleted.
So i think there is a probleme with the MCDS...
