4295.0. "COPY FAIL" by VAXRIO::LORENA () Fri May 16 1997 11:40

    
	Hello all,

	Our customer has the following problem:

Problem:
The customer lost the drive connection when he tried to copy big 
files to file service (>> 7MB) and the server disk was being used intensivily
(I/O intensive):

Note: If the VMS disk is NOT WITH INTENSIVE I/O, the copy works fine.

Could you help us ?
Regards,
Lorena

4295.2session didn't disconnectVAXRIO::LORENAThu May 22 1997 11:1313
    
    Adrie,
    
    I didn't find the notes that you suggested in your reply.
    If it possible, could you help me to find these notes or specific
    parameter to configure the session timeout ?
    I don't know if is a "session timeout" problem, because the customer
    though couldn't copy the big files, he didn't lost the connection, that
    is, he continue to access the network driver after the problem occur.
    
    Thanks for you attention,
    Regards,
    Lorena

    Careful Lorena.  When the client has the copy problem, to see if it's
    session was terminated, you can't check from the client - it will
    re-establish the session automagically whenever you try to use the
    connection again.
    
    So after the client aborts the copy operation - BEFORE DOING ANYTHING
    ELSE ON THE CLIENT - do $ NET SESSION \\client-computername and see if
    the session is really still there...and if you know they connected over
    DECnet do $ MC NCP SHOW KNOWN LINKS or, for IP (UCX) do UCX SH
    DEVICE/PORT=139 and see if the transport session is also gone...

    Paul, you are correct, the session at the problem moment disappear and
    when he execute a simple "dir command"in the drive, the session
    reconnect.
     
    Based in this information, is it possible help me to find wich
    parameter we need to increase to solve this problem ?

    Lorena,
    
    Now it gets hard ;o).  Though noone seems to be able to find a
    documented source, try doing the following and see if it makes any
    difference:
    
    Add the following registry DWORD value:
    
            Add new DWORD value named SessTimeout under
            HKeyLocalMachine\System\CurrentControlSet\Services\Vxd\vnetsup
    
            It has a min value : 10 and a max value : 30000
            default value (if not specified): 45
    
    You might try setting it to 90 or even 120 (seconds)...
    
    Please report your findings.
    
    Paul
4295.6the problem is solvedVAXRIO::LORENAFri May 23 1997 09:148
    
    Paul,
    We tested with the values 90, 120 and didn't work, then we tested with
    maximum value = 30000 (decimal) and it worked properly under Windows
    Explorer. For your information, under MS-DOS prompt, the copy didn't work.
    We consider the problem solved, and thanks e best regards for your
    prompt help and attention,
    Lorena
