Database: JIRA couldn't connect to your database

JIRA failed to establish a connection to your database.
This could be because:

• Your database isn't running
• The configuration of your dbconfig.xml file is incorrect (user, password, or database URL etc.)
• There is a network issue between JIRA and your database (e.g. firewall, database doesn't allow remote access etc.)

Hi Ben,

You may be aware that it's currently not possible to add JIRA to a Confluence instance in OnDemand, but there's something you can do about it.

First, follow the documentation here to create a new JIRA + Confluence integrated instance. Note that you'll have to place your current Confluence for destruction to be able to use the same domain. After the instance has been created, migrate your current JIRA data to it. Last, Restore your Confluence space backups on it.

So here goes a step-by-step:

Current Confluence instance:

1. Export Confluence spaces to XML.
2. If you are using Team Calendars, export the calendars.
3. Raise a support ticket for this specific request. Make sure to state that you have completed the above procedures.
4. Support will create backups of your instance's users and groups.
5. Support will then place the instance for destruction.
6. Once this has been completed, you can sign up for a new OnDemand instance through https://my.atlassian.com. Make sure that you choose JIRA and Confluence.

Current JIRA instance:

1. Backup your JIRA

New JIRA + Confluence instance:

1. Restore JIRA data
2. Report back to support that the instance has been created and JIRA has been restored.
3. Support would then perform the import of your Confluence users and groups (created previously) to the new instance, and some tweakings may also be done.
4. Import the Confluence XML space backups to your new OnDemand instance.
5. Import the calendars to Team Calendars.
6. Support may need to adjust permission settings in Confluence, since the groups are different in a JIRA + Confluence OnDemand as compared to Confluence-only OnDemand.

Hope it helps!
