<property name="hibernate.dialect">com.atlassian.confluence.impl.hibernate.dialect.MySQLDialect</property>

to the confluence.cfg.xml and restared but the error stay.

You should not be changing the confluence.cfg.xml - the installer should be setting that up correctly already

This is a database setting - you need to configure your database server correctly.  See for details on how to correct the settings on the database side.

Hi thx, n the link is descriped to set the property into the configuration.cfg.xml

Set the session isolation level in Confluence. In the top level of your Confluence home directory, find the confluence.cfg.xml file and locate the <properties> section. Add the following parameter:

Please read the document again, and look at the database configuration.

The confluence.cfg.xml will be set correctly by the installer, the doc is about repairing systems that may have missed the full upgrade.

You need to correct BOTH of these, not just one.


There are several options for fixing this:





    <property name="hibernate.connection.isolation">2</property>

 i cannot enter into the mysql.ini cause its a managed hosting

Yes, that is a little misleading.  You need to set it on the database side for it to persist.
