This article will explain in detail what the basic knowledge of WebLogic server is, and the content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

A technology is needed in an enterprise IT environment to enable multiple independent systems to "seamlessly" communicate with each other. WebLogic Server is a system that can bridge various data communication requests and handle system integration.

What is a WebLogic server?

WebLogic server is an application server that is used as a platform for developing, deploying and running multi-tier (n-tier) distributed Java applications. It also acts as a bridge between applications hosted on it and applications such as remote databases or message servers.

Oracle is the provider of the popular online transaction processing (OLTP) platform in the market, and the WebLogic server is one of the powerful tools to make Oracle a major competitor. They acquired the Java 2 platform Enterprise Edition (J2EE) server by acquiring BEA Systems in 2008.

WebLogic servers are located in the middle tier, just like proxies and firewalls. This is the layer between the front-end external application (usually an interface enabled with the external browser) and the database server (the back-end layer-the server where the data is stored).

From this middleware location, the WebLogic server centralizes application services, such as:

Web Services-various functions of the Web server

Business Services-Business components of the process

Back-end connections-enable connections to back-end storage devices and servers

In other words, this Java-based application server can achieve the best and simplified end-to-end performance of business processes. More importantly, it uses technical features such as caching and connection pooling, which means that WebLogic also helps reduce processing and transaction time. In addition, it provides enterprise-level security and powerful role management capabilities.

Basic WebLogic architecture?

In addition to acting as a J2EE server, WebLogic can also be used in the enterprise and manage other servers to manage the services running on it.

Domain: this is a collection of applications grouped together for ease of management. The domain consists of a management server and a plurality of managed servers under its control.

Base domain: this is a new domain with only administrative servers and nothing else. It may not be practical, but it can exist independently.

Managed servers: these servers exist in the domain and are used for a variety of purposes. Examples of such servers include SOA Suite,WebCenter Suite and Business Intelligence Suites.

Install the WebLogic server

To download a copy of the WebLogic server, you need to go to the Oracle Technology Network software download page. After accepting the license agreement and downloading your preferred version of the software, you can begin the installation.

Installation scenarios include:

Create a basic domain-every time you install a new WebLogic instance, a basic domain without a managed server is created by default. It doesn't actually do much until you add a managed server.

Create a managed server in the base domain-next, you will continue to create a managed server added to the primary base domain. This is called "extended base domain".

Create a managed server in a new domain-if you decide to run a managed server in your own domain, WebLogic allows you to clone an existing management server in the primary domain and use it to create a new domain for the new managed server. This is called an extended managed server.

Cluster managed servers-in this case, once the managed servers are installed in different domains, they can be "clustered" together and run by a management server that can reside in any domain.

No matter which installation method you choose, or the architecture configuration you initially choose, you can then rebuild the design according to the needs of the business process logic.

Apply WebLogic

Ideally, WebLogic can be well adapted to the technical environment of the business, where it can be configured in the following ways:

As a managed solution for all Java-based applications

Act as the home of a high-end website

The best security solution to solve the problem of slow connection between front-end applications and back-end servers

Become a bridge to deal with business scalability problems

In short, it can be said that WebLogic is an application server with future prospects. It can be used as an auxiliary tool for other Java applications, business suites and hardware devices that need to be included in the business data processing process.

What monitoring and management tools does WebLogic use?

This paper mainly introduces the three most popular WebLogic management and monitoring tools.

SolarWinds WebLogic performance Monitoring tool

Although it is a third-party product, the SolarWinds WebLogic performance monitoring tool is a management suite that covers all aspects of monitoring and managing WebLogic.

By looking at the functionality of this tool, we can gain an in-depth understanding of its actual functionality:

Monitor memory allocation and usage to ensure that the process is completed without consuming resources

Server and application monitoring to provide in-depth performance insight into threads and pools. This includes the current waiting time and the time it takes to execute the request, as well as tracking outstanding requests

After integration with the server and application monitor, the SolarWinds database performance analyzer provides detailed analysis and reporting of Oracle databases related to WebLogic

Monitoring databases, such as SQL Server,MySQL,DB2,SAP ASE and other databases, achieve almost 100% full communication in terms of data storage

Monitor virtual environments and applications such as VMware and Hyper-V, allowing replication and testing of simulation settings

BEA WebLogic Management console

You can access this native Oracle management console through a Web browser and run it from an Administration Server instance of the WebLogic domain. It uses a Java object called MBean, each of which contains a set of properties that define parameters for managing the different functions and operations of the server.

Tasks that can be done using this management tool include:

Start, stop instance and cluster configuration

Configure server services, such as database connection (JDBC) and messaging (JMS)

Security and management of users, groups, and roles

Configure and deploy Java applications

Monitor the performance of servers and applications and troubleshoot through server and domain log files

WebLogic Intelligent Dashboard and Monitoring (WLSDM)

WebLogic Smart Dashboard and Monitoring (WLSDM) is another third-party management and monitoring tool that is a console extension rather than a stand-alone solution.

Some of the powerful features of WLSDM include:

Simple, fast, non-resource-intensive installation, extending the unique advantages of taking snapshots of WebLogic domains

Can create an unlimited number of custom dashboards to meet the needs of administrator control and reporting queries

Easily create alerts and notifications by using the WLSDM metrics browser

Store and retrieve old data, including metrics, back-end data, and even alarms for comparison and analysis

Add and schedule scripts to facilitate management of CRON jobs

Advantages and disadvantages of WebLogic

Advantages:

It is one of Oracle's high-quality products with data security and integrity guarantee.

A powerful fail-safe solution that is necessary for mission-critical computing environments

Ability to draw complete charts on the WebLogic domain through compact reports for easy understanding and accurate decision-making

Disadvantages:

Compared with other similar software solutions, it may look a little bulky and bloated.

Not every small and medium-sized enterprise can afford quite complex license fees.

This is the end of what is the basic knowledge of WebLogic server. I hope the above content can help you to some extent and learn more knowledge. If you think the article is good, you can share it for more people to see.
