Was is the procedure to backup the Crowd JDBC Driver?


Upgrading from Crowd 2.12.0 to Crowd 3.1.2 fails constantly here, presumingly the new Crowd version does find the PostgreSQL DB on the Ubuntu 16.04 server. In Step2 of the upgrade instructions this item is mentioned:

     Back up your Crowd JDBC Driver if you have configured Crowd with a database.

What does that mean practically? (I mean, I do not perform any backup, since I can recreate anything from a snapshot.)

Which version of PostgreSQL DB are you using? Are you seeing any problems in logs that may indicate DB related problems? For example table or column not found?

Hello Marcin!

It's "postgresql-9.5                      9.5.12-0ubuntu0.16.04" on Ubuntu 16.04.4 LTS in Amazon Web Services (AWS).

No, we do not have any issues with connection problems to the PostgreSQL DB. What I am observing is that it's possible with Crowd 3 to login to Bamboo, JIRA, Confluence but not to Crowd itself. I am just trying to sort out as many incorrect settings as possible.

(I am recently trying to upgrade Bamboo, JIRA, and Confluence because I hope upgrading them will be easier.)

Will the documentation be updated? I don't think that I ever had  to fetch a JDBC driver for PostgreSQL, so I suspect the document describes version of software out of support…



Marcin Kempa Atlassian Team Mar 20, 2018 I've just created a support ticket for you. You should receive an email shortly. I believe it would be easier to share logs and communicate over the ticket and help you to resolve upgrade and login problems.

After the ticket is resolved, we will publish the solution if it is a generic one, so that others could also use the solution.


Best Regards,

Marcin Kempa

You might want to raise a support ticket with Atlassian to figure out your upgrade issues. Be sure to provide them with error logs.

In terms of backing up the JDBC Driver, Crowd (excluding WAR distribution) ships with PostgreSQL JDBC driver so you don't need to back it up.

KB to explain which type of Crowd installs require a manual download of the driver -

Hello Daniel!

I read this document. It seems pretty outdated. (Just hunting for clues why upgrade from Crowd 2 to Crowd 3 fails.)
