The information in this article applies to:
Using the administrative tool snap-in in the Microsoft Management Console (MMC), you can create two identically named Data Description Files (host column definition files, HCD files). (One physical file, so-named and having an .hcd extension, appears in the ..\sna\system subdirectory.)
It is possible, using the administrative tool, to make changes to both files listed in the MMC snap-in tree. However, when you do an MMC refresh, only one of the previously listed files remains. The changes are combined in it.
The combined changes indicated in the snap-in also appear in the single physical file in the ..\sna\system subdirectory.
There is an additional side-effect: A new file named New File.hcd appears in the ..\sna\system subdirectory and appears in the MMC snap-in tree list. It contains only a [Stats] section with a date-time stamp.
To work around the problem before it occurs, avoid defining Data Description Files with duplicate names.
Microsoft has confirmed this to be a problem in Microsoft OLE DB Provider for AS/400 and VSAM version 1.00, included with SNA Server version 4.0.
This problem was corrected in the latest SNA Server version 4.0 U.S. Service Pack. For information on obtaining this Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
