Confluence problem after Oracle19c upgrade?

[Torsten Fassian]

Hi,

I have upgraded the database of  Jira and Confluence to Oracle 19c today.

Jira has no problems.

But Confluence (6.15.6) gives the following errors in the log:

2020-03-23 15:45:58,793 ERROR [Caesium-1-4] [migration.agent.queue.QueueBroker] error An error occurred when getting the next batch for consumer type: CONFLUENCE_IMPORT. Message: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
com.atlassian.util.concurrent.LazyReference$InitializationException: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

....

Caused by: org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]
        at org.hibernate.service.internal.AbstractServiceRegistryImpl.createService(AbstractServiceRegistryImpl.java:275)
 ...

Caused by: org.hibernate.HibernateException: Access to DialectResolutionInfo cannot be null when 'hibernate.dialect' not set
        at org.hibernate.engine.jdbc.dialect.internal.DialectFactoryImpl.determineDialect(DialectFactoryImpl.java:100)
 

...

However Confluence seems to work from an enduser point of view. But I suspect there is something in the background not quite working the way it should.

I found something about this dialect problem here:

https://stackoverflow.com/questions/57715024/hibernate-dialect-for-oracle-19

But I was not able to solve the problem.

Does anyone have an idea how to solve this?

Thanks,

Torsten

Hi @Torsten Fassian ,

Oracle 19c doesn't seem to be supported for Confluence 6.15.x

Supported Platforms

Thank you Edwin.

So I'll have a look at the upgrade procedure for Confluence.

Thanks,

Torsten
