Is there a way to clear server caches without logging into the Admin Console?
Beginning in IBM TRIRIGA Platform 3.5.1, TRIRIGA delivered an enhancement for this to be done via workflow. The pertinent release notes can be found from this wiki page. Here is an excerpt from the release notes on the topic:
A custom task class has been added for workflow which triggers a global cache clear across all servers.
You can create a custom task and specify the following in the class field: com.tririga.platform.admin.cache.web.CacheProcessingCustomTask $RefreshAllCache
The custom task will perform a global cache clear on the server where the workflow runs as if it were triggered from that server’s Administrator Console. (Tri-211723)
