Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
A system-level software driver that is used by an EJB container or an application client to connect to an enterprise information system. A resource adapter typically is specific to an enterprise information system. It is available as a library and is used within the address space of the server or client using it. A resource adapter plugs in to a container. The application components deployed on the container then use the client API (exposed by the adapter) or tool-generated high-level abstractions to access the underlying enterprise information system. The resource adapter and EJB container collaborate to provide the underlying mechanisms-transactions, security, and connexion pooling-for connectivity to the enterprise information system.
Industry:Computer
The process of determining whether a user, device, or other entity is allowed to access a particular resource or a predetermined function (within a resource) via a specific access method. Based on definition found at http://www.csgnetwork.com/glossaryl.html
Industry:Computer
A system in which more than one processor can be active at any given time. While the processors are actively executing separate processes, they run completely asynchronously. However, synchronisation between processors is essential when they access critical system resources or critical regions of system code. See also critical region, critical resource, multithreading, uniprocessor system.
Industry:Computer
The process of associating the groups or principals (or both), recognised by the container with security roles specified in the deployment descriptor. Security roles must be mapped by the deployer before a component is installed in the server.
Industry:Computer
A system for classifying business establishments based on the processes they use to produce goods or services.
Industry:Computer
The procedures that restore the system to running all properly configured domains after one or more domains have been rendered inactive due to software or hardware failures or due to unacceptable environmental conditions.
Industry:Computer
A synchronisation mechanism for coordinating tasks even when data accesses are not involved. A barrier is analogous to a gate. Processors or threads operating in parallel reach the gate at different times, but none can pass through until all processors reach the gate. For example, suppose at the end of each day, all bank tellers are required to tally the amount of money that was deposited, and the amount that was withdrawn. These totals are then reported to the bank vice president, who must cheque the grand totals to verify debits equal credits. The tellers operate at their own speeds; that is, they finish totaling their transactions at different times. The barrier mechanism prevents tellers from leaving for home before the grand total is checked. If debits do not equal credits, all tellers must return to their desks to find the error. The barrier is removed after the vice president obtains a satisfactory grand total.
Industry:Computer
The principal that identifies the invoker of the enterprise bean method.
Industry:Computer
A subcomponent of XSL used for describing font sizes, page layouts, and how information flows from one page to another.
Industry:Computer
The point in a transaction when all updates to any resources involved in the transaction are reversed.
