Confluence Error with jmxContext during the installation

[Simon Ekstrand]

Hello,

I installed Confluence, on Ubuntu 16.04 with PostgreSQL.

After setting up DB connection getting the following error:

Could someone help me? Thx

Hello there! Thanks for reaching out, @Simon Ekstrand.

As I understand, you are having issues right after Confluence is installed and you try to connect with the database.

For starters, we could retry the installation from the ground up. Here you can have a look at our documentation:

• [Confluence Server 7] Installing Confluence on Linux

Keep in mind the following details while installing Confluence:

• The user running Confluence needs full read/write/execute permission on both <confluence-home> and <confluence-install> folders
• Your java version and database version need to be compatible with the version of Confluence being installed: [Confluence Server 7] Supported platforms

I have seen this issue before. One of the cases was triggered by having two (or more) tabs or windows interacting with Confluence during the database setup. So we can retry the install by making sure that we have only one point of interaction with Confluence.

The other one was caused due to a timeout and page reload combination. So looking out for this is a good idea. Even if the page times out, do not reload the page, wait for about ten minutes before doing so.

Now, I would like to have some details about your instance. Would you mind taking care of the following questions:

1. Which version of Postgres are you using?
2. Which version of Confluence are you installing?
3. Which version of Java are you using?
4. Is this a new installation or a migration?

Hope this sheds some light on the issue, Simon!

Hello Simon,

After reviewing your very helpful log output you included, it seems your error is related to the jmxContext. There is a KB which helps to describe further information about these types of error and provides steps to work around this issue. The workaround steps are as follows:

Resolution

It's possible that this is a one-time occurrence and may not require disabling JMX. If you find that the issue persists upon a second effort, continue with the resolution below.

If you experience any problems during Confluence startup that are related to JMX, it is possible to disable the JMX registration process. Please place jmxContext.xml in your <confluence-install>/confluence/WEB-INF/classes folder to do so. A restart of Tomcat will be required.

Source documentation: Unable to Start Confluence Due to JMX.

Please review and attempt the above workaround and let us know if it helps to resolve your issue.

Regards,
Stephen Sifers
