Confluence 7.11.1 Fails to Start Due to READ-COMMITTED error

My Docker instance of Confluence 7.11.1 has failed to start correctly with the following error:

MySQL session isolation level 'REPEATABLE-READ' is no longer supported. Session isolation level must be 'READ-COMMITTED'. See

I have checked the appropriate kb at

Both my.cnf and the confluence.cfg.xml were already set for the isolation level to be READ-COMMITTED.

I updated the JDBC string to include the sessionVariables parameter and restarted the instance.

The error still occurs - the strange thing is that nothing has changed since yesterday, when it was working fine.

Has anyone else experienced this?

@Milan Chheda [INFOSYSTA]Thanks for your reply - I had added that setting in my.cfg.

I discovered the issue - I had changed the file permissions on the my.cfg such that it couldn't be read by MySQL when starting up.

Strangely even having the setting in confluence.cfg.xml or adding the change to the JDBC didn't overrule the my.cfg.

Great to hear that the issue has been resolved. Did you found out how the permissions changed suddenly?

confluence.cfg.xml can't override MySQL configuration file (my.cnf). So, you will have to update it manually, followed by restart of the respective services.

Just to confirm you added below line in my.cnf, followed by restarting the MySQL service.


 And restart Confluence after updating confluence.cfg.xml.
