OK, after the installation of TSM CLient 6.2.5 db2 backup is not working.. see
():[db2d] /db2/db2d/tsm -> db2adutl query full
Error: Initialize environment failed with TSM return code 610
Believe me, I've been more than hour and half searching but no success... maybe you have an idea about this...
I seems to be a variable environment issue
