Manageability Manageability refers to the level of information that a running system provides, and the capability to tweak settings related to that information. For example, Oracle Coherence provides a cluster-wide view of management information via the standard JMX API, so that the entire cluster can be managed from a single server. The information provided includes hit and miss rates, cache sizes, read-, write- and write-behind statistics, and detailed information all the way down to the network packet level. Additionally, Oracle Coherence allows applications to place their own management information and expose their own tweakable settings through the same clustered JMX implementation. The result is an application infrastructure that makes managing and monitoring a clustered application as simple as managing and monitoring a single server, and all through Java's standard management API. | |
