A JSP element that can act on implicit objects and other server-side objects or can define new scripting variables. Actions follow the XML syntax for elements, with a start tag, a body, and an end tag; if the body is empty it can also use the empty tag syntax. The tag must use a prefix. There are standard and custom actions.

Maintains cache coherence by reading from local caches until a write occurs. To change the value of a variable the writing processor first invalidates all copies in other caches. The writing processor is then free to update its local copy until another processor asks for the variable. The writing processor issues an invalidation signal over the bus and all caches check to see if they have a copy; if so, they must invalidate the block containing the word. This scheme allows multiple readers, but only a single writer. Write-invalidate use the bus only on the first write to invalidate the other copies; subsequent local writes do not result in bus traffic, thus reducing demands on bus bandwidth. See also cache, cache locality, coherence, false sharing, write-update.

A JSP declaration, scriptlet, or expression whose syntax is defined by the JSP specification and whose content is written according to the scripting language used in the JSP page. The JSP specification describes the syntax and semantics for the case where the language page attribute is "java".
Industry:Computer
A JSP container that can run a Web application that is tagged as distributable and is spread across multiple Java virtual machines that might be running on different hosts.

Interruption of the normal Solaris operating system environment indicator, readable from the service processor. Absence of heartbeat updates for a running Solaris system usually indicates a Solaris software hang.

A JMS administered object that encapsulates the identity of a JMS queue or topic. See point-to-point messaging system, publish/subscribe messaging system.

A JavaServer Faces EL expression that refers to a property of a backing bean. A component tag uses this expression to bind the associated component's value or the component instance to the bean property. If the component tag refers to the property via its value attribute, then the component's value is bound to the property. If the component tag refers to the property via its binding attribute then the component itself is bound to the property.
Industry:Computer
A JavaServer Faces EL expression that refers to a method of a backing bean. This method performs either event handling, validation, or navigation processing for the UI component whose tag uses the method-binding expression.

Interconnection topology describes how the processors are connected. All networks consist of switches whose links go to processor-memory nodes and to other switches. There are four generic forms of topology: star, ring, bus, and fully-connected network. Star topology consists of a single hub processor with the other processors directly connected to the single hub, the non-hub processors are not directly connected to each other. In ring topology all processors are on a ring and communication is generally in one direction around the ring. Bus topology is noncyclic, with all nodes connected; consequently, traffic travels in both directions, and some form of arbitration is needed to determine which processor can use the bus at any particular time. In a fully-connected (crossbar) network, every processor has a bidirectional link to every other processor.
Commercially-available parallel processors use multistage network topologies. A multistage network topology is characterized by 2-dimensional grid, and boolean n-cube.
Industry:Computer
A JavaServer Faces class that defines the behavior and properties of a JavaServer Faces UI component.
