Saikat Nag

Oracle Application Database Administrator at RP Sanjiv Goenka Group

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.

Erick Karanja

Technical Lead at Cellulant Kenya

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."

"The tool's technical support is very good."

"I would rate Oracle WebLogic Server nine out of ten, possibly even ten points."

"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."

"One of the good features of Oracle WebLogic Server was the ability to add some custom parameters to its deployment and performance."

"Oracle WebLogic Server is secure."

"The solution works well in load balancing."

"It is good because it's easy to use. It doesn't crash frequently like other servers."

"We can manage every application by creating a managed server and a cluster."

More Oracle WebLogic Server pros

"Tomcat is a simple, light environment, whereas the full Red Hat Fuse solution is heavier."

"Tomcat is a lightweight application server, which makes it easy to deploy and install small applications."

"The most valuable feature is the free EE server."

"The most valuable features of this solution are the general web server features."

"It is easy to manage at a basic level."

"It is easy to set up."

"The solution is convenient. It is a comfortable and easy-to-use solution for my use cases."

"The most valuable feature of Tomcat is its ability to export libraries into different instances so that I can use it not only in one application but in multiple applications."

More Tomcat pros

Cons

"I would like to see integration with MQ systems."

"Having clearer mechanisms to directly map a database-level connection problem to the corresponding WebLogic thread would greatly enhance the administrator's convenience."

"The quarterly updates can sometimes lead to instability depending on the configuration of systems."

"I can't point to anything missing."

"The error handling area in Oracle WebLogic Server is an area of concern where improvements are required."

"Configuration can be a significant challenge, demanding a deep understanding and expertise."

"Oracle's support team fails to understand the real problem of the customer, which is why they take time to resolve issues."

"Oracle WebLogic Server's configuration could be improved because we need to do multiple configurations when setting up anything."

"The administration is hard, and it is more complex to use than others."

More Oracle WebLogic Server cons

"If Apache can come up with a better solution to provide better security, that would be ideal."

"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."

"Resource configuration like JNDI and queue configuration, similar to other servers, should be provided from the admin console for Tomcat."

"Security integration in Tomcat is complicated. We need to use another tool to solve the security issues."

"I would personally like it if the admin console would show more information specifically about memory being used."

"The stability must be improved."

"I think that Tomcat needs a more robust logging error details feature; the current logging feature is available, but it should be more user-friendly."

"The current procedure appears complex and could benefit from a more straightforward solution."

More Tomcat cons
