Steps to Reproduce

Root Cause

Auto discovery of nodes in SMA comes from the distributed cluster definition kept in the hazelcast cluster.

If the nodes in the cluster are not synchronized, then it is possible that the node definitions found by SMA can be missing or out of date.

This can happen if not all nodes are restarted and the node that is stopped did not gracefully leave the cluster. In most cases the nodes should enter and leave the cluster and update the cache.

Resolution

Make the following change to the operating environment:

1. Shut down all the nodes in the cluster.
2. Truncate pegadata.pr_sys_statusnodes table.
3. Restart the nodes.

At this point SMA has a consistent and valid view of the cluster.
