Hi Fidel,
No the database isn't 10GB it's 740GB it's oracle 10g.
Don't know about whether the performance issues have resolved as a result cause I only made the changes yesterday and the business don't work weekends. I'll find out on Monday / Tuesday if it's made any difference.
Sorry I should have mentioned when I created the new tablespace with BRTOOLS I incorrectly specified all for the class parameter and didn't realise until this error. I've since corrected IAORA and TAORA entires as they had changed all the data classes to use this new tablespace.
Thanks
Craig
