RE: [xwiki-users] New XWiki installation with Oracle

3 Mar 2006

Srini,

I'm not sure what your problem is.  I'm not using the "news" feature,
so
can't offer any suggestions in that area.  The XWiki distribution
contains a seed data set for MySQL, and I understand that this data set
includes some data required by the system.  It's a bit tricky to get the
data into Oracle (MySQL sql client allows direct insertion of text and
LOB columns, but Oracle SQL*Plus doesn't).  I set up a MySQL db with the
seed data and then wrote a program to read it from MySQL and write it to
Oracle.  May be you're missing some of the important seed data?

John

Thanks a million, John, I am much further now.  Many features of the
XWiki work fine.  I could even attach a 120K file.   In addition to the
steps below, I had to set 'batch_update' size to 0 in hibernate.cfg.xml
.

There are still problems though.   Under 'News' heading in the front
page, no categories show up.  I can not edit any categories as well.
What might be going on here?  Is it possible that this is just an access
rights issue?  

Another notable problem is that, I cannot edit XWiki preferences.  Which
table/ row should I modify to edit this entry?

Also, there is a ClassNotFound exception for XWiki.XwikiSkins in
xwiki.log.  This file is not included in the distribution.

Thanks in advance,
Srini

I've attached a zip archive that contains some files that may help you
get up and running with Oracle.  My stuff does not give a 100% solution
- there are still some issues with attachments.  You'll find these files
in the zip:

* xwiki-db_ora_tab.sql - script to create Oracle schema
* hibernate.cfg.xml - hibernate config (I'm using the Oracle OCI JDBC
driver because the thin driver apparently has some size issues with
LOBS)
* xwiki.hbm.xml - hibernate mapping (I'm using a custom type for
nulls/empty string conversion)
* String2.java - hibernate custom type

I wrote a small program to read the data from the MySQL seed database to
the Oracle schema.

I hope this helps.

Regards, John

Subject: [xwiki-users] New XWiki installation with Oracle

Hi All.

I have recently downloaded and installed xwiki on mysql. It was so
smooth and impressive, we wanted to use it enterprise wide and need to
get it working with Oracle for that.  So, far I haven't been able to
deploy it properly. 

Our Environment - Oracle 9.0.2 database, with Oracle 10g JDBC Thin
drivers; Running in Tomcat (4.1.31)

Used both the schema from the attachment in the 'oracle' page of
www.xwiki.org/xwiki/bin/view/AdminGuide/Oracle and also generated the
schema using Hibernate hbm2ddl (Oracle Dialect).  I am unable to get
this deployed with Oracle database.

1. Can someone in the list, who has success with Oracle + Xwiki (at
least past where I am at), send a hibernate mapping file (xwiki.hbm.xml)
that worked for Oracle?
2. In addition to the steps outlined in the page above, are there any
other steps needed to get it working on Oracle?  Can this be done with
reasonable config/code/db changes?
Any pointers to debugging this further are much appreciated.
Here is the problem I am currently facing.
When I point my browser to the xwiki main page (out of the box), I get
the StaleObjectStateException exception while saving 'multilingual'
preference.
