We're using .NET 2.0 TransactionScope on a Vista client. By default this will create a distributed transaction using MTS which will then be proxied using Oracle Services for MTS. However we consistently get the following error:
ORA-00161: transaction branch length 100 is illegal (maximum allowed 64).
According to this thread http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=943955&SiteID=1 Microsoft made some changes in MSDTC in Vista which are likely to have caused this problem. They say they were co-ordinating with Oracle to determine an appropriate fix.
Is this an acknowledged issue? Has it been fixed and if not, when will it be fixed?
