Q. To build a parallelized solution for a problem that’s intrinsically better-suited to parallelization or that, for want of resources, needs to be chunked.

Q. GridGain works with a GridTask, which specifies how to handle the main unit of work of the interface type:-

View solution

Q. When you call the method on the service with the @Gridify annotation pointing to this GridTask implementation, it stops execution of method and loads an instance of this implementation.

View solution

Q. When using GridGain stem mostly from the fact that what you develop on one node can’t always automatically work on another node with no additional configuration.

View solution

Q. GridGain lets you start up nodes using the startup script in the:-

View solution

Q. To hoist a grid node into existence.

Q. When you use the script that comes with the distribution is the class:-

View solution

Q. A GridLoader instance is responsible for many things such as:-

View solution

Q. GridFactory.start can take as its first parameter a:-

View solution

Q. The file which enables you to tell GridGain about which GridTask classes are deployed:-

View solution

Q. Instances of the ApplicationContext can be injected into the various GridGain class instances (GridTask, GridJob, and so forth) using GridGain:-

View solution

Q. This is the default implementation. It is used when you run gridgain.sh or gridgain.bat.

View solution

Q. This is likely the second most useful implementation. It provides a servlet that bootstraps the GridGain instance inside any web container as a servlet.

View solution

Q. A workflow system extricates that process state from the domain and into a separate layer, called a business process.

View solution

Q. A workflow engine lets you model the process in a higher-level form:-

View solution

Q. A language that, when deployed to a BPEL container, describes the execution of a process.

View solution

Q. The main feature common to traditional workflow systems is the ability to support work lists for actors in a process.

View solution

Q. This provides a set of diagramming notations that describe a business process. This notation is akin to UML activity diagram.

View solution

Q. A way of letting your process rest in a known condition indefinitely.

View solution

Q. A pause in the action that can only move forward when a known actor or agent in the system moves it forward.
