This article was previously published under Q230145 SYMPTOMS
Mtxoci.dll is a dynamic-link library (DLL) that is used internally by the Microsoft ODBC Driver for Oracle and the Microsoft OLEDB Provider for Oracle in conjunction with Microsoft Distributed Transaction Coordinator (DTC) to provide transactional support to Oracle databases. Specifically, it translates the DTC transactions into the XA transactions that Oracle can understand. This component currently has no way of tracing the DTC and application messages received by it nor XA messages sent by it. This can make troubleshooting some problems extremely difficult.
CAUSE
This is a design limitation.
RESOLUTIONWindows NT Server or Workstation 4.0
A hotfix (ID: 051099b) is available that enables logging in Mtxoci.dll. This fix can help in troubleshooting problems when using the DTC transactions and an Oracle server. When used in conjuction with the Oracle XA tracing, it can help narrow down problems very quickly.
