Hi, As this issue is mainly related to Oracle which is manufactured by a company independent of Microsoft, we are not the best resource to troubleshoot this third-party product issue. I suggest contacting Oracle for direct assistance. Oracle forum: http://forums.oracle.com/forums/main.jspa;jsessionid=8d92079030d6c3589a458f1546a3b9f58f4fde5c6f94.e38Qb3qMa3eRbO0LaNqQaNaPb3qSe0?categoryID=84 I hope your issue can be resolved soon.
