Configuration Manager for Jira (CMJ) is compatible with Jira Data Center.
What is the effect of CMJ operations on Jira Data Center cluster performance?
Jira Data Center allows you to run a cluster of multiple Jira nodes providing a stable performance under high load. The CMJ operations (snapshot creation, deployment, integrity check, etc.) always run on a single node. This is the node where the user is logged in currently and starts the operation from.
Running CMJ operations on a single node ensures that your Jira performance across all other nodes remains stable and no slowdowns in response time occur. Your Jira performance will be affected only on the node where the CMJ operation is running.
Don’t use the ClearCacheEvent option
As of Configuration Manager for Jira 6.13.3, the option to “Send ClearCacheEvent to clear Jira's internal caches after deployment” in General Settings has been removed. Additionally, the Clear Caches button in Advanced Utilities has also been removed.
That’s because triggering them may lead to issues within your Jira instance. So, if you’re currently using an older version, DO NOT USE the ClearCacheEvent option or the Clear Caches button.
