Unable to start Confluence after upgrading from 7.11.2 to 7.12.2

jprateragg

We just upgraded from Confluence 7.11.2 to 7.12.2 on Windows. The upgrade was successful. However, after starting the service after the upgrade, the Confluence page would not note. In Chrome, it just spins and spins and spins.

We are using MySQL 5.7.33 with the mysql-connector-java-8.0.25.jar connector.

I am new to having to troubleshoot Confluence--it's just always worked for us.

I am honestly stumped and do not know where to begin. I appreciate the help. Thanks!

EDIT: If someone can tell me what logs to post (and where they are) I can do that. I don't see an "attach" option here so not sure how I would post these.

EDIT: I am getting these errors in the MySQL log only after I kill the Atlassian Confluence service. I have not changed anything in my.ini. Once I kill the Atlassian service, I get like 20 of these entries in the MySQL error log.

I was able to resolve this issue by upgrading MySQL from 5.7.33 to 5.7.34. I do not know what is different about these two versions--being as though it is a very minor upgrade. But it resolved my issue. Like I said before--I did not make any changes to MySQL when upgrading Confluence--I only upgraded Confluence. Don't know if this will help anyone else.

We did not make any changes to MySQL when upgrading Confluence.

Hi @jprateragg ,

There could be different reasons that can cause start up issues. Log files are vital to give suggestions. You may check for JVM max and min memory parameters and increase them if required.

https://confluence.atlassian.com/confkb/how-to-fix-out-of-memory-errors-by-increasing-available-memory-154071.html

Also check if you can see any db related errors in the logs.

Niranjan

OK, Seems to be mysql related. Check this https://community.atlassian.com/t5/Jira-Software-questions/Connection-problem-with-MySQL-5-7-Got-an-error-reading/qaq-p/1399490

@jprateragg I am getting same error , I am trying to upgrade Confluence from 6.11 to 7.13. You mentioned "resolve this issue by upgrading MySQL from 5.7.33 to 5.7.34", I didn't get this part. Can you please explain.

Your help is much appreciated.

jprateragg

Hey @Manoj Tumati -- So I was running a older version of MySQL, 5.7.33. Because I'm on Windows, I just launched the MySQL Community Installer and updated it to 5.7.34 just to see if it would make a difference. It did. I don't know why, but it just worked.

Manoj Tumati

@jprateragg Thank you , I think I found the issue.

I am trying to install 7.13v on Oracle 12 release 1 which doesn't support.

I have to upgrade to lower confluence version to avoid this issue.
