Jira Core 8.6.x upgrade notes
Here are some important notes on upgrading to Jira Core 8.6.
For details on the new features and improvements in this release, see the Jira Core 8.6.x release notes.
Upgrade notes
Increase pool-max-size
If you're upgrading from Jira 7.x to Jira 8.x we recommend changing the pool-max-size parameter to 40 in your dbconfig.xml before the upgrade. Leaving the default of 20 can sometimes lead to “ResultSet Closed” errors during re-indexing on 8.x. For information on implementing the change, see Tuning database connections.
API change for JXM monitoring
To make sure no unauthorised users can tamper with JMX monitoring, we have changed these two GET endpoints to POST:
http://jjira2.com:8080/rest/api/2/monitoring/jmx/startExposing http://jjira2.com:8080/rest/api/2/monitoring/jmx/stopExposing
Support for PostgreSQL 10
We’ve added PostgreSQL 10 to our supported platforms. For more info on how to connect Jira to this database, see Connecting Jira to PostgreSQL.
Configurable scheme parameters in Jira REST API for projects creation
Now you can fully automate creating new projects with specific workflowSchemes. We have extended Jira REST API and added a new endpoint and a new parameter:
POST /rest/api/2/projectwith a new optionalworkflowSchemeIdfield to create a project and assign a worflowSchemeGET /rest/api/2/project/{projectKeyOrId}/workflowscheme- get info aboutworkflowSchemeconfigured for a project
New information in the audit log DATA CENTER
This new check verifies that you’re using the recommended JVM configuration for code cache memory. Insufficient code cache memory can impact performance. This check is already available to customers who manually update the ATST app to 1.30.0. It will run automatically. Learn more
As an admin, you have now more insights into what's going on on your instance. We've added several important pieces of information to help you get a full set of info you can track and manage.
These are the new available items:
- Dark feature enabled/disabled
- Jira service deleted
- Project role created
- JMX monitoring enabled/disabled
New JVM code cache check DATA CENTER
This new check verifies that you’re using the recommended JVM configuration for code cache memory. Insufficient code cache memory can impact performance. This check is already available to customers who manually update the ATST app to 1.30.0. It will run automatically. Learn more
Cluster monitoring DATA CENTER
We've extended the capabilities of the Atlassian Cluster Monitoring plugin that was so far bundled with Confluence and Crowd to monitor Jira clusters as well.
This way you have now more tools to manage your data center nodes. We're displaying all your clustered nodes on a separate page with the information on node uptime (since last restart), ID, load and memory. The list will only show active nodes so a node which is down will not be displayed. The information available on the page can also help you decide if a node you've just added to the cluster has been configured correctly.
To see the clustering information, go to Jira Administration > System > Clustering. To drill down and see runtime and system information, click More for a specific node.
End of support announcements
