Re: Fw: 353401389: Cannot Delete a File In QDLS, QSYS.LIB or QOPT through IBM ® NetServer? - File May Be in Use

[Neil Palmer/DPS <neilp@xxxxxxxxxxx>]

Thought we were taking people who allowed deletion of files in QSYS.LIB 
from Windows out back and shooting them?   ;-)

Found out that certain Windows fixpacks have made it a bear to delete 
files from QDLS via a share.  IBM is working on a fix.  However it is 
recommended that you do not try to delete files from QDLS, QSYS.LIB, QOPT 
from a Windows share.  Well, I still had a directory that I used in QDLS 
that I suppose I should follow my own advice and move to do a different 
directory.

 Document Title:Cannot Delete a File In QDLS, QSYS.LIB or QOPT through 
IBM®
NetServer? - File May Be in Use
 Document Description:
  Fixes for the Microsoft® Windows XP professional operating system modify
the behavior of the Microsoft® Windows® network client in such a way that
files in the QDLS, QSYS.LIB and QOPT file systems can no longer be deleted
through requests from this network client.  Windows XP Hotfix Q812937 has
been identified as the specific fix introducing the change in behavior of
the Windows XP network client.  Hotfix Q812937 is also included in Windows
XP Service Pack 2.

Fixes for the Microsoft Windows 2000 operating system also modify the
behavior of the Windows network client in such a way that files in the
QDLS, QSYS.LIB and QOPT file systems can no longer be deleted through
requests from this network client.  Windows 2000 Hotfixes KB867778 and
KB885835 have been identified as the specific fixes introducing the change
in behavior of the Windows 2000 network client.  Hotfixes KB867778 and
KB885835 have not yet been included, to the best of our knowledge, in a
Windows 2000 Service Pack.

This change modifies the way that the client tries to delete files. Rather
than sending a request to delete the file, the client now sends a request
to set the file attributes with a flag indicating that the file should be
deleted.  This will fail with files or folders in the QDLS, QSYS.LIB and
QOPT file systems due to the design of these file systems when accessed 
via
the Integrated File System.  The change attributes and delete requests are
handled by different functions:  one to change the attributes and one to
perform the delete.  The delete cannot succeed because the change 
attribute
request causes the file to be in use.  The design of the QDLS, QSYS.LIB 
and
QOPT file systems has not changed since the introduction of the Integrated
File System in V3R1.  This failure occurs because of the change in the way
Windows tries to delete the file, not because of any change to IBM® 
OS/400®
or IBM® i5/OS?, the IBM® NetServer? or any PTF applied to the IBM® 
iSeries?
family of servers.  The same request to other file systems in the
Integrated File System work without failure.  The problem happens only in
the QDLS, QSYS.LIB and QOPT file systems.

To circumvent the problem when it occurs within QDLS, the files can be
moved from folders in the QDLS file system to directories in the root file
system.  This approach has the added benefit that the root file system
integrates more tightly with the Windows operating system than QDLS ever
could.  However, there is a chance with this approach that programs on the
iSeries family system that use QDLS documents must be rewritten to use
stream files.

An update to iSeries NetServer is being made to work around the new 
Windows
client delete procedure.  APAR MA30361 documents this IBM code change.
