Hi

I got a lagacy system using Hibernate3 (version 3.3.1.GA). It is currently connected to a oracle 11g database. We are planing to upgrade the database to oracle 12c. But I have trouble to run my test against oracle 12c. Some of my queries behave differently when comparing timestamp fields. I also get alot of "Batch update returned unexpected row count from update [0]; actual row count: 0; expected: 1" in different senarios. If I switch back to oracle 11g everything work fine. Its part of the story that I upgraded from ojdbc6 to ojdbc7.

So what I need to know before I dive to hard info my problems: Is this suposed to work. ie Running hibernate3 against oracle 12c. Or do I need to upgrade hibernate?

Best regards

Marius

I posted before trying with the latest driver.

I have Hibernate 3.1.1 GA working with Oracle 12c using the ojdbc7.jar and org.hibernate.dialect.Oracle10gDialect.

Haven't fully tested, but could connect and perform queries. I'll post back if any issues arise.

Thanks.

Hi,
I am in a similar situation. We are upgrading oracle from 11g to 12c. My application is using hibernate3.jar which is 3.6.8-Final version. It works great with 11g using Oracle10gDialect but when I connect to 12c database I get below error.

Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to determine Dialect to use [name=Oracle, majorVersion=12]; user must register resolver or explicitly set 'hibernate.dialect'

I tried downgrading till 3.1.1 and upgrading till 3.6.10-Final. Below 3.6.8 my code wont compile as there is no Oracle10gDialect class before that. And even 3.6.10-final version gives me same above error. I cannot upgrade to Hibernate 4. Any advise will be of great help. thank you.
