I have an error in atlassian-confluence.log after upgrade

Hello there!

Ovanes, this trace takes us to a problem with the database during the upgrade. So, first thing we could start by checking is:

1. Database compatibility
2. Database Driver
3. Connection string that points to the database
4. Your server.xml file maxThreads value (and all other parameters context)

We have seen this situation before. There were two situations where this error popped up:

• Unsupported database
• Missing maxThreads parameter

Further, never forget to back up <confluence-home> and <confluence-install> folders as well as your database prior to any upgrade.

Also, upgrades should always be tested on a test instance before applying them to the production instance.

You will want to look into these:

• Supported Platforms - Confluence 6.15
• Database JDBC drivers

Looking forward to your reply Ovanes!

Thanks for help.

Certainly, I've made back up <confluence-home> and <confluence-install> folders and database.
In that problem case, I used back up and upgraded 6.14.0->6.14.3. It's enough for CVE-2019-3396 now.

[Diego]

Hello there! You are correct, both CVEs are addressed on Connie 6.14.3:

Confluence Security Advisory - 2019-04-17 | Confluence - Path traversal vulnerability - CVE-2019-3398

Confluence Security Advisory - 2019-03-20 | March 2019 Confluence Server Advisory - WebDAV and Widget Connector vulnerabilities

Is your instance working as expected now?

Let us know!

[OVANES OGANYAN]

Yes, everything is ok now.
Issue is closed.

I'll plan next upgrade more accuracy :)

Thanks for the feedback!
