RE: [xwiki-dev] Getting XWIKI to run on DB2
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?

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.
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..
Second question: Is this most likely the cause of the Tomcat exception (see TOMCAT Exception below) that I am receiving below?
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.. Ludovic
