XA_END May Return an Exception Error in Microsoft Distributed Transaction Coordinator (810967)


The information in this article applies to:

  • Microsoft COM+ 1.0, when used with:
    • the operating system: Microsoft Windows 2000
  • Microsoft Windows 2000 Advanced Server SP3
  • Microsoft Windows 2000 Advanced Server SP2
  • Microsoft Windows 2000 Advanced Server SP1
  • Microsoft Windows 2000 Advanced Server
  • Microsoft Windows 2000 Server SP3

  • Microsoft Windows 2000 Professional SP1
  • Microsoft Windows 2000 Professional

SYMPTOMS

This problem occurs when you create two XA connections in a test application:
  1. The test application points both connection objects to the same database, and both connection objects use the same user ID and password.
  2. The test application creates two XA connections, gets the XAResource object from each connection, and creates an XID.
  3. One of the XAResource objects becomes associated with a transaction branch. The object does some work, and then the object is suspended.
  4. If the other XAResource object does more work on the same transaction branch and calls the XA_END function, an XA exception error occurs and the XA_END call returns -3 in Microsoft Distributed Transaction Coordinator (MSDTC).

CAUSE

This problem occurs because an internal transaction manager join flag (TMJOIN) is handled incorrectly in the XA_START function. If you specify this flag, a new transaction is always created for the XAResource object to join, regardless of whether an existing transaction is found for the object to join.
