How To Change Default XML Storage
As per the bellow the default XML storage has been changed in 11gr2.
We have a application which works fine on r1 but not on r2 due to this change, we are going to investigate resolving the issue on the application in the future, in the mean time we need to be able to use the CLOB storage.
Oracle Database 11g Release 2 (18.104.22.168) New Features in Oracle XML DB
The following Oracle XML DB features are new in Oracle Database 11g Release 2 (22.214.171.124).
Default Storage Model for XMLType
The default XMLType storage model is used if you do not specify a storage model when you create an XMLType table or column. Prior to Oracle Database 11g Release 2 (126.96.36.199), unstructured (CLOB) storage was used by default. The default storage model is now binary XML storage.
Does any one know where we can change this functionality back to the pre 11gR2 change?
I think this is an option to be specified at table creation time, like:

PAVB, that sounds right to me. Last spring I was responsible for a particularly painful migration of a database from Solaris to Linux where the customer relied on XML type columns based on XSD schema's. they "didn't have" the source XML schemas, so I tried to reverse engineer them and only with two weeks left before cut over did they give me what I needed. IMHO, I would think that using CLOB and having the front end manage the XML schema would be easier then letting Oracle do it.
