Experience in using Confluence with Oracle 19c?

Does anybody here have some experience using Confluence with Oracle 19c, despite the green light from Atlassian for using 19c?

Is anybody running Confluence 7.x and Oracle 19c and experienced problems?

I just wanted to know if we should give it a try :-)

We have got a 250-user server-version, and our DBAs want to upgrade to 19c until the end of 2019...

Hi @Werner Lembacher , 


at the moment Confluence is not compatible with Oracle 19c, however there is an open ticket that you can follow for this :

You can vote for this issue or comment on it if you want this to be prioritized :)


Let me know if this helps, 



I have an existing installation of Confluence, which has been up and running for several years.

When you say "not compatible", do you mean 'won't work and it'll stop dead' ?

Or do you mean 'some things will fail' ?

Or it 'can't take advantage of new features' ?

Or is it listed as 'not compatible' because it hasn't been tested yet ?
(which is an answer I consider perfectly understandable and acceptable, btw.)

I kinda need to know since time is running out. Our DBA wants to do the Oracle 19C update. I'm the only one he's waiting on.


I found this in our Confluence installation with 19c:

ERROR Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set

in …\Confluence\logs\atlassian-confluence.log

an suspect it to be a problem related to this bug:
