![]() ![]() This section lists the new features in Oracle Enterprise Manager Cloud Control 12 c. You can use the same deployment procedure to updates nodes as well. ![]() You can maintain an Oracle Coherence setup image or gold image in the Software Library and deploy it throughout the infrastructure to create completely new clusters or add nodes an existing cluster. The JVM Diagnostics feature is part of the WLS Management Pack EE and Management Pack for NonOracle Middleware.Įnterprise Manager provides a complete provisioning solution. You can drill down to a Coherence node's JVM from within the context of a cache and a cluster to identify the method or thread that is causing a delay. You can customize topology view to show some key performance metrics as well.Īll of the Coherence Management features are integrated with JVM Diagnostics and provide real-time visibility into the node JVMs. The Topology Viewer provides a high level topology of the entire cluster and shows the relation between caches, nodes and hosts. You can compare configurations of multiple nodes which helps identify performance bottlenecks caused by configuration changes. The drill down views allows you to determine the root cause of performance problems or simply identify performance trends in the Coherence Cluster.Įnterprise Manager provides a centralized cache data management feature that allows you to perform various cache operations such as add/remove index, view cache data, view query explain plan, and so on.Įnterprise Manager monitors the changing configuration of the nodes over a period of time. You can overlay metrics for multiple nodes or caches in the same or different cluster for detail analysis to provide detailed visibility at the desired level. Highly customizable performance views for monitoring performance charts and trends are available. You can see the association of the caches, nodes, hosts and also Oracle WebLogic targets using Coherence*Web applications. ![]() You can correlate cluster nodes with the underlying hosts to determine CPU and memory utilization on those hosts in order to make better decisions for scaling your clusters. By including metric extensions in export or imported monitoring templates, multiple metric extensions can be easily shared at the same time between Enterprise Manager deployments. Metric Extensions are the next generation of User-Defined Metrics, which enable you to extend Enterprise Manager to monitor conditions specific to the enterprise's environment by creating new metrics for any target type. ![]() You can export and import monitoring templates to share monitoring settings between different Enterprise Manager deployments. You can create a monitoring template by pre-populating the monitoring template with metrics for a Coherence target. Nodes and caches can be proactively monitored by the Incident Management feature. The Cluster Home page provides immediate visibility into the worst caches in the system based on hits-to-gets ratio which is an overall health indicator for the cluster. The Cluster Home page displays an overview of the performance hotspots such as nodes with minimum available memory, publisher and receiver success rate, and nodes with maximum send queue size. It is composed of many individual nodes or java processes which work together to provide highly reliable and high speed virtual caching.Įnterprise Manager provides deep visibility into performance of all the artifacts such as caches, nodes, and services. Oracle Coherence is an in-memory data-grid and distributed caching solution. ![]()
