I have upgraded confluence from 5.8.4 to 6.11.1 & after the upgrade ./startup.sh was showing tomcat started successfully. But upon trying to access confluence getting error as below :

Could not load bootstrap from environment

BootstrapException: Unable to bootstrap application: The database driver (oracle.jdbc.OracleDriver) was not found in the class path.<br/>This Confluence installation cannot be upgraded automatically. Please see Confluence documentation:<br/>https://confluence.atlassian.com/display/DOC/Database+Configuration

Anyone has encountered this kind of error before ?

According to the error, it says that the database driver can't be found (ie: you need to install the Oracle driver.)  Have a look at the doc and there is a link to the driver download.

Hi Dave,

I am new to using confluence so need some clarification. As this is upgrade just copying jdbc drivers will work ? And does it have any version dependancy ?

[Dave Theodore [Coyote Creek Consulting]]

Most likely that will do the trick.  I linked you to the Atlassian doc above on what to do.  In order to confirm which versions of things are supported, check out the Supported Platform page for the tool and version in question (page for 6.11.) While you're there, I would recommend verifying that you are using supported Java and Oracle database versions as well.  Things may work if you are not running a supported platform, but you may encounter odd issues.

Pro-tip on how to find the correct Supported Platforms page: Use Google and search as follows "confluence <major.minor version> supported platforms" Now you can select from the dropdown and choose the appropriate version, but that method works well for all of the Atlassian documentation. By including the version in your search, you can find the details about your version, which may be different to other versions.

Good luck!

Hey Dave,

Thanks for the help, it did resolve the issue & I was able to start confluence successfully by just downloading & copying jdbc drivers.

Hello @Vishal , @Dave Theodore [Coyote Creek Consulting] ,

Could you please help me out with how you did it. I am facing the same error when I have upgraded my Confluence from 6.6.8 version to 7.4.0 version.

I am getting the same fatal error. Also, please let me know if there is anything in Oracle versions which is related to or is dependent on the Confluence Enterprise versions.

Kindly help me out as I am getting System error and I am not able to open my Confluence.

@MANISHA KAUSHIK  I had downloaded new ojdbc8.jar driver from the below link & replace the file with existing. After that I tried to restart the confluence & it did work for me.

Hello @Vishal , @Dave Theodore [Coyote Creek Consulting] ,

I did all the required changes to my database and have changed the driver as well that was needed. But now I am facing the below error.

Could you please help me with this, as what needs to be done next, as I am not able to trace the bug, as why is this error message coming!!

Best Regards,

Manisha

Hello @Vishal ,

I just recognized one issue. I did the RCA and found there is an issue with SSL Authentication with LDAP Server which is causing Login error. 

Hope this needs to be solved by my team itself. I will reach out to you in case of other help.

Best Regards,

Manisha
