What is the exact problem.. I've been able to download the file fine:

I attempted to download the "latest" code
from the link on the
AdminGuide-Backup page and it failed to download. Is this available
anywhere else?
Thanks,

I think this is very bad.. it probably means the field to hold the
versioned data is too small.. Even if you manage to load this row, it
will probably mean that after a while the content for this field won't
fit in the row.. This probably means the database conversion hasn't
transformed this field to a sufficiently big field..
I suggest you try loading the db using the import/export script I
published today at http://www.xwiki.org/xwiki/bin/view/AdminGuide/Backup
It's a cleaner way to import the default DB as it will use the xwiki
hibernate schema update and loading..
I suspect xwiki does not like the constraints that have been put in the
DB2 database.. This could be critical.. let's see how it goes with the
other import method..

I have finally been able to migrate the basic
mySQL database structure and
data to DB2, with the exception of one row that is contained in the XWIKIDOC
table. The primary key for the row is XWD_ID = 104408758, XWD_NAME =
XWikiPreferences. When I attempt to import this row into DB2, I get the
following error.
DB21034E The command was processed as an SQL
statement because it was not
a
valid Command Line Processor command. During SQL
processing it returned:
SQL0102N The string constant beginning with "'head
1.8;\naccess;\nsymbols;\nlocks; strict;\ncomment @# @;\n\n\n1.8\" is too
long.
SQLSTATE=54002
Even though I was not able to load this row, I thought I might try to
start the XWIKI servlet against the database. When I attempt to access the
main page, I get the following error (see web error below).
First question: Does anyone know how to get this
row inserted, or is
there a smaller alternate row that would suffice.
Second question: Is this most likely the cause
of the Tomcat exception
(see TOMCAT Exception below) that I am receiving below?
