Regroup Using the API
The cluster regroup API can be run as a web service or from the command line. This API issues a regroup command to all nodes that are reachable and recycles their connections while setting the timekeeper to the node where the command was issued. This does not require a cluster reboot.
From Studio you can navigate to the Web Service:
/services/webservices/system/admin/server/operations/repairCluster
When using the API for regrouping, specify REGROUP as the option.
