RES: Problem with ONBAR: unusually slow on IDS ...

In Response To: Re: Problem with ONBAR: unusually slow on IDS .... (Khaled Bentebal)

Khaled,

I met this bug in Nov 2010. In my environment, this query used to take more than 24 hours to start transfer data to tape. I upgraded to 11.50.FC8 and solved the problem.
