I would like to have my custom hibernate.cfg.xml with my own mappings for my
application entitities.

Hello,
I have following scenario.
I have process that sometimes creates subprocess. The subprocess has several
async actions (I call ESB service). The super process checks result value of

Yes, I agree. But the db will block the second update until transaction with
first update commits.
I think that optimistic locking needs READ COMMITTED isolation level of
transactions. Nothing more, nothing less.

I use Oracle and when I try to set isolation level of data source to

SERIALIZABLE are the only allowed isolation levels.

There is written that Oracle offers the read committed and serializable
isolation levels, as well as a read-only mode that is not part of SQL92. Read

I don't know why but I thought that StaleObjectStateExceptions are errors. But
in docs (chapter 6.5) and in JIRA

it doesn't matter if these exceptions occur.

Yes, I've read. It seems to me that all JIRAs around this were closed with
fixes available in version 3.2.2. I use 3.2.2 and still have problems.
