Hello,

i have to unload a table which contain 570 Millions rows.

But before i would like to know how much time does it take ?

Did an unlod put locks on a tbale durring the unload.

Il the Unload abended, in which state is the table (accessibel ?)

Thanks for your help.

unload takes shared-locks (read-locks).
and does not affect table accessibility.

If you do have imagecopies (which I should hope) you might want to consider UNLOAD FROMCOPYDDN.

OK.

Thanks.
