The WebLogic scripting and management features available with Coherence 12c Managed Servers make it easy to create Coherence clusters and manage applications. Using the Weblogic Scripting Tool (WLST), the whole lifecycle of Managed Coherence Servers can be controlled, from creating and starting a Coherence cluster to deploying Coherence applications.
WLST scripts are written in Jython and can manipulate Weblogic JMX MBean's to manage Weblogic and Coherence. The flexibility and power they provide make it easy to create, configure and startup up a complete Coherence environment - in just a few minutes. This post will outline how to do just this, using some sample WLST scripts.
In a distributed environment, deploying a user-defined data structure as cluster wide service can provide access to all its operations, from anywhere in the grid. For example, you can have your own implementation of a distributed SecureMap, which auto-encrypts its values and is deployed as a service on all the cluster nodes.
In GridGain, you can implement your own custom data structures and deploy them as distributed services on the grid. You can also access them from clients via service proxies…
When storing data in a distributed cache, Map is the most obvious data structure. But, there are times when applications need to process data in the order it is received. GridGain In-Memory Data Fabric, in addition to providing standard key-value map-like storage, has an implementation of fast Distributed Blocking Queue.
Getting real-time notifications to users is a popular feature in social media these days. For example, notifications in Facebook that notifies users of any new likes or comments they receive on their posts or pictures. Or a leaderboard in an online game, that refreshes as a new leader emerges with a greater score.
