Dtcxatm.log File Grows Unexpectedly Large

ID: Q229613

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server, Enterprise Edition version 4.0

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.

CAUSE

This problem occurs because of an error in the way that space is reclaimed in the log file.
