Sun Microsystems is a multinational vendor of computers, computer software and hardware, and information technology services.
In a shared memory multiprocessor machine each CPU and cache module are connected together via a bus that also includes memory and IO connections. The bus enforces a cache coherency protocol. See also cache, coherence, Mbus, XDBus.
Industry:Computer
A fatal error occurs in the SAX parser when a document is not well formed or otherwise cannot be processed. See also error, warning.
Industry:Computer
In a multiprocessor system, true parallel execution is achieved where a large number of threads or processes can be active at one time. See also concurrence, multiprocessor system, multithreading, uniprocessor.
Industry:Computer
A distinct, individual item that can be included in an XML document by referencing it. Such an entity reference can name an entity as small as a character (for example, <, which references the less-than symbol or left angle bracket, <). An entity reference can also reference an entire document, an external entity, or a collection of DTD definitions.

Solaris threads are implemented as a user-level library, using the kernel's threads of control, that are called light-weight processes (LWPs). In the Solaris environment, a process is a collection of LWPs that share memory. Each LWP has the scheduling priority of a UNIX process and shares the resources of that process. LWPs coordinate their access to the shared memory by using synchronization mechanisms such as locks. An LWP can be thought of as a virtual CPU that executes code or system calls. The threads library schedules threads on a pool of LWPs in the process, in much the same way as the kernel schedules LWPs on a pool of processors. Each LWP is independently dispatched by the kernel, performs independent system calls, incurs independent page faults, and runs in parallel on a multiprocessor system. The LWPs are scheduled by the kernel onto the available CPU resources according to their scheduling class and priority.
Industry:Computer
A method of messaging that includes blocking until a response is received.
Industry:Computer
A messaging system that implements the Java Message Service as well as other administrative and control functionality needed in a full-featured messaging product.
Industry:Computer
Security decisions that are made by security-aware applications. Programmatic security is useful when declarative security alone is not sufficient to express the security model of an application.
Industry:Computer
A messaging system built on the concept of message queues. Each message is addressed to a specific queue; clients extract messages from the queues established to hold their messages.
