9810.0. "patch for data corruption??" by HGOV05::SUBBU () Wed May 14 1997 04:04


Hi

We are facing data corruption in Trucluster environment ( Digital unix 
V 4.0B and Trucluster V1.4). The sytems are AS2100 5/300 connected to 
common scsi onto HSZ40.

When a client machine tries to copy a large table he gets an error
ora-1578.  What we were told by Oracle guys is that there exists a
operating system patch having the following description:

SIM_TORT patch for KZPSA on Digital UNIX 4.0

Could some one Please get me the pointer AS soon as possible. 

Thanks in advance,
Subbu

    guru does not seem to support anonymous ftp.
    
    how is a field person supposed to get this patch?

Please ensure you report a problem if you have it, or
at least verify the status of the patch before installing...

    Eric, could you elaborte on your comment? What verify of the patch are
    you suggesting? Are you suggesting we wait for a released patch rather
    than use the unoffical one.
    
    This problem has been handled very poorly from a field view- We were
    ony given a vauge description of the problem, but it went out as a
    blitz which implies urgency. There is no information on the
    conditions that cause the problem, so customers have to guess if it
    applies to them.
    
    Im getting a lot of heat from customers. Usually no one wants to
    install an unoffical patch, but if we knew the risk we might decide to
    in this case.
    
    You never give customers confidence by hiding facts from them.

I think if you have questions, they should be sent to the
USEG support group.  I think passing around unofficial patches
is a sure way to have trouble.

  The USEG group should know who has unofficial patches so they
can track if there are problems...patches are usually unofficial
because we don't have data to show it fixes the customer's problem, or
we are concerned the patch may not work (or both).

I don't have specific data on this patch to comment, USEG would have it.
I don't feel good point folks to unofficial patches, especially if it
is not USEG doing it.

    re .-1 --
    
    On the whole I agree with this completely, as I've seen too many cases
    of people installing patches for the wrong version of the operating
    system.
    
    However, in this case, these unofficial patches are the ones that USEG
    sent out a blitz about, encouraging wide distribution.  So they're about
    as officially unofficial as you can get. :)

    When will this patch be released? (and with what number). 
    
    The Oracle support people here have heard of it and seem to think it is
    the cure for all sorts of problems, including those with the system we
    are building. Should we quiet them down, or are their real problems in
    simport.

9810.9Blitz is correct: install the test patchRUSURE::GOODWINEverything you know is wrong.Tue May 20 1997 10:4419
    Hello,
    
    The blitz is correct.  If you have a data corruption problem on the
    KZPSA, which is simport driven, then you need the latest simport
    patch, which fixes not only the data corruption problem but also
    some panics caused by spo resource queue problems.
    
    The official patch will be available in the next official Digital
    UNIX patch kit.  If you need the code now, you can get it in the 
    form of a test patch from:
    
    	guru:/usr/guest/misc/osf/simport/*.tar
    
    The test patch is the same code as the official patch, but it is
    available now, and it is supported by USEG.  Many sites have 
    installed the test patch to fix data corruption and other problems.
