Comparing and propagating changes

Most of the performance degradation in a running system is due to configuration changes and Enterprise Manager can help you to track down the configuration and performance differences between two different nodes, two caches, connection managers, or connections. Think about the case where, for example, you rolled out some changes to the cache configurations of your storage nodes and, by mistake, you did not propagate that change to one node and that node is not performing as expected. You can then use the compare configuration feature. You can access this either using the Administration link from the Coherence cluster page or each component page, for example node or cache. You can select the two nodes or caches to compare and you will see the comparison as in the following page:

You can compare both configuration and performance between two nodes and track down the difference between them.

You can then use the real-time configuration change propagation feature...
