Hello,
Ok it works fine now ...
First I stopped and started HDB in putty, it was green but i could'nt connect to.
I had to update DB to 1.00.48.372797 (vs 1.00.28.361821), and install a new licence file 
See http://scn.sap.com/docs/DOC-30980 and http://scn.sap.com/docs/DOC-31036
Perhaps could it help someone ...
