1z0-599 Exam Dumps : Oracle WebLogic Server 12c Essentials

* WebLogic Server supports Fast Connection Failover, a Oracle feature which provides an application independent method to implement RAC event notifications, such a detection and cleanup of invalid connections, load balancing of available connections, and work redistribution on active RAC instances.

* A GridLink data source uses Fast Connection Failover and responds to Oracle RAC

events using ONS. This ensures that the connection pool in the GridLink data source

contains valid connections (including reserved connections) without the need to poll

and test connections

A Node Manager process is not associated with a specific WebLogic domain but with a

machine. You can use the same Node Manager process to control server instances in

any WebLogic Server domain, as long as the server instances reside on the same

machine as the Node Manager process. Node Manager must run on each computer

that hosts WebLogic Server instances—whether Administration Server or Managed

Server—that you want to control with Node Manager.

The following principles encourage RESTful applications to be simple, lightweight, and fast:

* Resource identification through URI

* Uniform interface: Resources are manipulated using a fixed set of four create, read, update, delete operations: PUT, GET, POST, and DELETE. PUT creates a new resource, which can be then deleted by using DELETE. GET retrieves the current state of a resource in some representation. POST transfers a new state onto a resource. See Responding to HTTP Methods and Requests for more information.

* Self-descriptive messages

* Stateful interactions through hyperlinks
