SYMPTOMS

When Microsoft SQL Server is used with an XA-compliant resource manager (for example, Oracle, IMB DB2, or Informix), the Dtcxatm.log file can grow quite large. For example, it is possible for files to reach several hundred MB in size. Therfore, when recovery is performed, Microsoft Distributed Transaction Coordinator (DTC) reads through the entire log file. This can lead to extremely long recovery times.
