If you have set up application links to more than one of the same application type, e.g. you have linked your application to two JIRA servers, then one of the servers will be marked as the 'Primary' link. This means that any outgoing requests will be directed to the primary link's application.
For example, if you have set up a Confluence server that is linked to two JIRA servers with two-way authentication for both links, you can nominate an application link to one of the JIRA servers as the primary link. Every time Confluence requests JIRA information (e.g. for a JIRA issues macro), it will request it from the primary link's JIRA server. Note, both JIRA servers can still make requests of the Confluence server (e.g. a Confluence page gadget on the dashboards of each JIRA instance).
Please read about making a project link the primary link, for information on how primary project links also influence the information shared between servers.
Making an Application Link the Primary Link
To make an application link the primary link:
- Log in as a system administrator and go to the administration page. Click 'Application Links' in the administration menu. The 'Configure Application Links' page will appear, showing the application links that have been set up.
- Click the 'Make Primary' link next to the application link that you want to make the primary link. A '' symbol will display in the 'Primary' column next to the application link.
The 'Primary' column and 'Make Primary' link will only display if you have set up application links to more than one of the same application type, e.g. you have linked your application to two JIRA servers.
