Hi!

For Oracle varchar2 can have maximum 4000 chars. So after 80 PUT commands slide 
crashes on that document because 'version-set' property length of history object 
(for example /history/1) is exceeded.

So I would like propose new schema for Oracle (what is really important is 
property value stored as clob) and patch to JDBCDescriptorStore that works with 
this schema:

SCHEMA :

--Slide schema for user_5 9.0.0.0.
--Modified for named primary keys 11.09.2003.

drop table children;

drop table property;
drop table revisioncontent;

create table locks(id varchar(4000), object varchar(4000),
