A Cluster is very similar to a Context. There are certain operations found in a Context that are not relevant to a Cluster. For example, it doesn't make sense binding a context to a Cluster. A Cluster is supposed to contain a set of object references, not contexts. However, a Cluster interface shares many of the same operations with the Context interface, such as bind, rebind, resolve, unbind and list operations. This common set of operations pertains to operations on a group.

The semantic of the resolve operation of the Context Interface is slightly enhanced to support Clustering. You setup a Cluster by binding the Cluster object into the Context with a particular name. And when the client tries to resolve against the Cluster name, a member of a Cluster is returned based on a pre-determined criterion, rather than the Cluster itself. In this way, client programs can continue to use the Context interface but still enjoy the benefits of Clustering.

Ans: Life cycle management is a service that one must take from application server for the EJB components. That's why the programmer will never define any method related to life cycle management of the EJBs. But then he/she has to declare those methods and let the ejb container implement the same. Home interface is used for declaring such methods. Ex: crate, find, remove etc. The reason that we need to declare these methods is to specify the list of input and output parameters.

ConTeXt is a macro package developed by Hans Hagen of Pragma-Ade. ConTeXt is a document-production system based, like LaTeX, on the TeX typesetting system. Whereas LaTeX insulates the writer from typographical details, ConTeXt takes a complementary approach by providing structured interfaces for handling typography, including extensive support for colors, backgrounds, hyperlinks, presentations, figure-text integration, and conditional compilation.

The principal difference is that an abstract class is used when you have a type/subtype relationship. An interface does not imply a type/subtype hierarchy; it merely forces a class to have some methods with a given signature. That allows some other code to rely on being able to call those methods. You want to subclass abstract classes when you are making subtypes that define the abstract behavior. The subclass should have a "kind of" relationship to the superclass.

If you observe a number of cases with a common association, such as a single classroom or activity, or numbers that cause you concern, seek the advice of the local health department.

The iSchool has one dual-processor Xeon server available for research computing use. For historical reasons, it is named 'cluster'- at one point a cluster was ...

project members share the common desire to make a positive contribution to the developmental process of the Internet as a form of open and peer-to-peer media.

Both Cluster and Osagent provide Round Robin load balancing facility. But they are of very different nature. You get load balancing from Osagent for free. When a server startups, it registered itself automatically with the Osagent and this in turn allows Visibroker to provide an easy but proprietary way for the client to get a reference to the server. However, all these automation comes at a price. You have no choice in determining what constitutes a group and the members of a group.

Computers are readily available to students in both the department's and the library's computer clusters. Together, about 50 computers are available to students and the wait is rarely long, if any.

Elementary schools are grouped into nine geographic clusters: North, Northeast, Northwest, Queen Anne/Magnolia, Central, South, Southeast, West Seattle North, and West Seattle South. Each "cluster" has four or more elementary schools, and each school within a cluster has an attendance boundary, called a reference area.

LabPro has all the features of our Universal Lab Interface (ULI) and many more. It features automatic sensor recognition with six independent channels: four analog and two digital. LabPro can be used with a computer or a TI graphing calculator. It can also be used as a stand-alone data logger. When used with a computer, it can be connected to the serial port or a USB port. It collects data faster than our ULI and supports analog output. LabPro is also less expensive than the ULI!

a general rule, we follow native MS Windows conventions as much as possible. 21.4 is a fairly complete Windows application, supporting native printing, system file dialog boxes, tool tips, etc. In cases where there's a clear UI conflict, we currently use normal Unix XEmacs behavior by default, but make sure the MS Windows "look and feel" (mark via shift-arrow, self-inserting deletes region, Alt selects menu items, etc.

Do you have any ideas on how I can make a posterboard for my project, I don't have enough money to get a big one. Perhaps you could find a large cardboard box (for free at a local store or market) that you could flatten and use the clean inside part for your poster.

Jonathan Biggar (July, 1998) : Yes, the client will establish a second security context for the new target. Nick Battle (July, 1998) : First we should clarify a few terms. A host is a machine which runs processes, each process possibly under a different user-id. CORBA objects run in processes; several different objects can run in the same process. Credentials are not "for" a host, a process or an object.

The Global JXDM is an object-oriented model that takes advantage of property inheritance to reuse components. This helps to keep the total number of elements smaller. However, this also means that some specific data element names do not exist in the dictionary because more generically named properties are inherited down to the more specific subtypes. For example, the Global JXDM does not contain an ArrestDate element.

These rituals were built on the foundations of their cultures, and to truly understand them, one must understand the culture first, and then the ritual. In general, these rituals formed a powerful element of these cultures' spiritual and cultural life.

MS. SCHULTEN: I have an interesting perspective on it because I used to work for a couple practice management vendors, large practice management vendors that serviced one doctor to ten doctor physician practice. Let me tell this is a loaded question. There are physicians out there who have purchased software to do claims submission. 800 bucks. Their palm pilot costs more than what they are doing claim submissions on.
