Offers efficient load distribution with a scope of high scalability
Our organization configures Oracle WebLogic Server in such a way that a load balancer becomes available. The network requests are segregated to the Oracle WebLogic Server as the managing server and different nodes are configured. Using the product as a load balancer helps automate request transfer from one non-functional node to another functional node. Due to Oracle WebLogic Server, the endpoints remain unaffected whenever a node goes down. The clustering feature enhances our organization's performance and reliability. In our organization, the health of the Oracle WebLogic Server environment is maintained and managed using Oracle Enterprise Manager (OEM). I would definitely recommend others to use Oracle WebLogic Server. Overall, I would rate the solution an eight out of ten.

Offers high availability, straightforward deployment and easy to use
Tomcat could be a little bit more innovative. Tomcat could come up with a framework that's more lightweight and purely targeted at Java applications. Some other solutions are doing better right now, maybe because they have come up with MicroProfile, which I think is moving forward. It may actually beat Tomcat because of the lightweight nature of the framework, the MicroProfile. They're coming up with new solutions. So, for the future of Tomcat and to maintain the market share they might be looking for, they need to come up with initiatives to ensure that several of us have a lightweight framework to deploy applications on.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The products offers EE support."
"WebLogic is reliable, and it's easy to use for development."
"The product's installation phase is easy."
"Oracle WebLogic Server is more secure and has full functionalities that can be used for big applications."
"Another valuable feature is the ability to automate tasks through scripts, making our environment highly efficient."
"The technical support is responsive. They are always ready to help by various communication channels, such as Zoom calls. However, sometimes it will take a while because when we are dealing with a problem, they need to look at the logs and configuration. A lot of the issues are related to the configuration that they need to look at thoroughly before they can give us a solution and it can take a few days depending on the type of problem."
"I recommend the product because the installation is easy, it provides a secure environment, and it's easy to manage. The solution provides easy monitoring. Accessing all the logs is easy, and deploying application versions is smooth."
"The solution works well in load balancing."
"What I find most valuable in Oracle WebLogic Server is its flexibility in administering and managing applications, along with the built-in dashboards that offer high visibility into vulnerabilities."
"I would rate the pricing a ten out of ten, where one is high price and ten is low price. The pricing is pretty low."
"It is a scalable platform."
"The product is easy to use."
"The product's initial setup phase was simple."
"Tomcat is a lightweight application server, which makes it easy to deploy and install small applications."
"The ease of use of Tomcat is its most valuable feature. Once we grade particular software, we simply download it and we keep an eye on if Tomcat is working."
"One of the most valuable features of Tomcat is its compatibility with the Apache web server and its ease of configuration. It is simple to set up and maintain and allows for easy management of database connections, transactions, and isolation. Overall, Tomcat is a user-friendly application server that makes it easy to manage various aspects of database interactions."
"The product's most valuable feature is the ability to host applications."
 

Cons

"I would like to see integration with MQ systems."
"If you want to use Oracle products to the fullest with enhanced customizations, you need to get trained. There is enough documentation and the flexibility to configure the application to your needs but you will need to spend more time gathering the knowledge."
"I've had issues with some of the tracking features tracking and have had to go back to several generations of code to fix problems where things were touched."
"The tool's implementation should be easier. The product is also expensive."
"The error handling area in Oracle WebLogic Server is an area of concern where improvements are required."
"I can't point to anything missing."
"There's a bug related to the managed services."
"The integration could be improved."
"This is a complex application."
"Tomcat needs to improve its user interface."
"Sometimes, the UI part does not run properly, or the server goes down."
"The product needs to have more updates."
"One way to improve the solution is by making the logging capabilities of Tomcat better by providing a logger within the server itself and making it easy to access and view the server logs. This can be especially useful when debugging issues with applications deployed on the Tomcat server. By having the ability to view both the application logs and the server logs, you can more easily identify the source of any issues and troubleshoot them more efficiently. Providing a connector or other similar feature that allows you to access the server logs from within your application can also be helpful in this regard. Having access to both the application logs and the server logs can be a valuable resource when trying to identify and resolve problems."
"Tomcat's performance is less than other solutions like IBM WebSphere or JBoss."
"Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."
"The disability and memory management is a problem with the solution and has room for improvement."
"The interface is not user-friendly."
