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 https://confluence.atlassian.com/confkb/confluence-fails-to-start-and-throws-mysql-session-isolation-level-repeatable-read-is-no-longer-supported-error-241568536.html 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.

hmmm

There are several options for fixing this:

[mysqld]
...
transaction-isolation=READ-COMMITTED
...

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

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

I read all suggestions how to solve this when installing new software for first time, and the only solution was to go into phpmyadmin and execute command:

SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED;

Yes, that's what the docs tell you to do.

Not really Nic, no where in any documentation you can find what Frantisek Bekes posted above . . . unless you find that in a "eyes only Atlassian" paper?

Frantisek solution has been the only one that has worked so far.

I would suggest Atlassian to review their "official" documentation.

Oddly, I can find it in the installation docs, and the healthcheck docs and the troubleshooting docs. For example, https://confluence.atlassian.com/doc/database-setup-for-sql-server-9258.html
