A Tale of Two SQLs 2004-05-03 - By Tim Gorman
Dan,
I think that you 've hit upon the only possible explanation, especially
regarding your comment that "eventually it will get a 1555 error ". The
flip-side of ORA-01555 (See ORA-01555.ora-code.com) is more work spent rebuilding a consistent read...
Hope that the support folks return the right answer... :-)
