It does not always have to be the root context of your directory structure. For instance, if you were to use the file system as a directory structure for JNDI, the root context would be C:.
You know this because all the directory objects are stored under this context. It does not, however, have to be the initial context. The initial context is merely the starting point that you select to traverse through the application. If you were to write a JNDI program to locate all the text files in the Windows temporary directory, the initial context might more appropriately be C: Windowstemp instead of C:. Take a look at object O3 in the diagram in the slide.
You bind it to two contexts: A and B. Does the object that is bound to two different contexts exist once or twice in the naming service? Or, worded differently, is the object accessed by value or by reference? That is, there are multiple copies in the tree.
Modifying an object under a context does not change the same object that is under a different context. In the tree in the slide, object O3 actually has two instances.
The first instance lives under context A, and the second under context B. If the following context exists: SomeObject Without first creating: Subcontexts are referenced through simple dot delimitation—for example, the name com. HR as opposed to uk. You cannot insert an object into the naming service unless its subcontext exists. Suppose SomeObject refers to an object in the examples context, which is a subcontext of com.
In this example, you cannot bind an object named com. SomeObject unless the ejb subcontext is first created. JNDI will not automatically create the subcontext because the name of the bound object has a subcontext listed in it.
JTA specifies standard Java interfaces between a transaction manager and the parties involved in a distributed transaction system: The JTA specification was developed by Sun Microsystems in cooperation with leading industry partners in the transaction processing and database system arena. JTA is meant for bean-managed persistence.
Enterprise messaging is now recognized as an essential tool for building enterprise applications. By combining Java technology with enterprise messaging, the JMS API provides a tool for writing enterprise applications that communicate with each other asynchronously. Enterprise messaging provides a service for the asynchronous exchange of events and business data throughout an organization.
The common concepts of subscriber, publisher, producer, consumer, and queues are supported by all JMS technology—compliant messaging systems. The configuration decision for JMS is if and where to store messages—memory, database, or plain files—or not store them at all.
It is not acceptable to force a user to enter multiple passwords and to synchronize these passwords. The single sign-on framework specified by JAAS solves this problem. Oracle WebLogic Server by itself does not support single sign-on currently.
However, there are several ways to achieve this using the Oracle Identity Management suite. With the Pluggable Authentication Module PAM framework, you can add multiple authentication technologies without having to change existing login services. You can use the PAM framework to integrate login services with different authentication technologies.
JDBC enables a database vendor to develop a product without worrying about how the database will be accessed. All that is needed is a JDBC driver, which acts as a contract between the vendor and the clients. Similarly, the client can switch from one database to another without worrying about compatibility. For JMX, it is a similar situation. In theory, JMX enables decoupling of the managed device from its management software.
The device vendor develops the management beans MBeans along with its device, so clients can automate the management of the device seamlessly. The current JCA version 1. JCA features include: An application client is any client that can communicate with a distributed system. These clients can be heavyweight or lightweight, based on the amount of business processing that is performed on the local client. Some people may differ on whether a browser application such as Java Swing could be heavyweight, or whether all browser applications are by definition lightweight.
Although Web clients are technically application clients, a distinction is made so that you understand the context that is being discussed you will know that Web client instantly implies HTTP communication. An EJB container is an environment that manages session beans stateful or stateless , entity beans, and message-driven beans.
A browser is a piece of software that can interpret and display an HTML page in its correct format. Web clients interact with Oracle WebLogic Server by sending requests for pages. Also, advanced Web clients can display XML pages. Do not assume that a Web client is a PC; it could be a phone or kiosk or any other kind of device. A proxy server is a piece of software that accepts a request on behalf of a client and forwards the request onto a machine that satisfies the request.
The proxy server typically maintains some sort of mapping mechanism to determine which type of client requests gets forwarded to which servers. A proxy server decouples clients from the server that provides the implementation for the client.
This level of indirection gives administrators and architects a level of security and the ability to reconfigure the back-end network without impacting the existing clients.
A reverse proxy also known as a page cache is a form of proxy that caches page requests in memory, and then when repeat requests come for the same pages, the cache looks for recently used URLs and returns those pages without having to fetch them again. This greatly speeds up the response time. In addition, reverse proxies can have a request filter for example, allow if match, deny if match. Web Server Web servers: Modern-day Web servers are optimized for the rapid distribution of pages to many concurrent users.
To accomplish this, a Web server may provide special file mappings, frequently accessed caches, or other features. Many Web servers support some sort of technology in which a client-side page can invoke the operation of a server-side CGI program. Web servers can also proxy a request that they receive to application servers that run the Java EE applications. Oracle WebLogic Server provides proxy plug-ins to popular Web servers that allow the Web server to proxy requests that are intended for the Oracle WebLogic Server elements.
The Oracle WebLogic Server plug-in can also round-robin these requests to a variety of machines in a cluster, thereby providing a basic level of scalability.
WebLogic Server includes a built-in Web Server. Firewalls are a security measure. Often, in large applications, there is a firewall between your Web server and your application server. Physically, a firewall is often part of an IP router. An application server is software that can service the requests of applications. You can think of an application server as the CPU for a large distributed system. An application server is a coordinator, facilitator, supporter, and manager of the distributed architecture activities of a distributed system.
To perform these tasks, popular application servers have support for components, CGI programs, message- oriented middleware, transaction monitoring, persistence management, timing services, email support, and many other technologies that an enterprise application may require for full-featured support.
In this environment, you see the usual invisible firewalls. Often, your client has one and your Web server usually has one. Presuming that you have relatively sensitive data in your application server, you probably would add another firewall to further isolate your enterprise data. Here, you see that there are still applications that do not run on browsers. They use the World Wide Web infrastructure to access your application server but they probably get to your server via some EJB that is exposed through a registry.
The same service is available to local clients as well. Firewalls, which normally are not shown in these diagrams, are shown here to emphasize that you cannot rely on just any protocol making a round trip through the system. Quiz Oracle WebLogic Server True 2. False Answer: Practice 2 Overview: Defining Terminology and Architecture There is no practice for this lesson.
To aid others in replicating your work, you make templates of the domain configurations you created. These are not copies as such, but templates to let others pick up where you left off. The Oracle WebLogic Server installation program can be used in the following modes: If you want to run the graphical mode installation, the console attached to the machine on which you are installing the software must support a Java-based GUI. If you attempt to start the installation program in graphical mode on a system that cannot support a graphical display, the installation program automatically starts the console mode installation.
The console mode installation is an interactive, text-based method for installing your software from the command line, on either a UNIX system or a Windows system.
The silent mode installation is a noninteractive method of installing your software that requires the use of an XML properties file for selecting installation options. You can run the silent mode installation in either of two ways: The silent mode installation is a way of setting installation configurations only once, and then using those configurations to duplicate the installation on many machines.
Typically, the Installer requires approximately 2. To specify the temporary directory location tmpdirpath , perform the following steps: Set the java.
