Hello confluence team,

I installed the update with the installer file. And when opening the weblink comes this error:I searched in the atlassan-confluence.log and found this:

Could You help me, what I should do? If you need more information, let me know.

Thank You.

Hello,

Could you confirm with me which database and version you are running Confluence on?

Thank you!

Kind Regards,

Hello,

Oracle XE 11g

Kind Regards,

Marcus

[Shannon S]

Thank you, Marcus.

Confluence currently only supports Oracle 12c (release 1), and this has been the case for a while now.

I would recommend that you first upgrade your instance of Oracle to 12c, and then re-attempt the upgrade.

Let us know if you have any questions.

Kind Regards,
Shannon

Thanks for your reply.

I will check this. It is also depends of our license of oracle.

Or I migrate to sql server or postgres.

Thank you. I will let you know which decision I will make.

Kind Regards,

Marcus

Marcus,

No worries! What might be happening now is that the database user has too many permissions. Have a look at Database Setup for Oracle - Create user with schema-creation privileges, especially this part:

Notes:

• It is very important that the user is granted the exact privileges indicated above. Confluence requires only these privileges so you should grant specific privileges to the user, and not assign a role to the user.

• Do not grant the user the select any table permission. That permission can cause problems with other schemas. 

• When you create a user, specify the tablespace for the table objects as shown above.

I would still recommend that you upgrade Oracle to a supported version, however, to avoid future issues.

Let us know if you have any questions

Kind regards,

Shannon

Great news. Confluence works.

Many thanks for your help Shannon.

I had any-permissions. And I revoke these permissions.

But in the future I go to a supported version.

Kind regards and Thanks :-),

Marcus,

Glad to hear that worked for you! :) 

If you run into any issues when upgrading your database or migrating it please feel free to raise a new question.

Take care and kind regards,

Shannon
