Provides integration with Eggplant but problems with stability

We use Windows Server only for Eggplant Manager. Otherwise, I'm not using it At the moment, we have big problems with stability, and I'm not very happy at the moment. So, the stability could be improved. I have been using it for a few years. The initial setup is complex. We have an…

Migration to a modern interface enhances AI integration and cloud capabilities

Presently, Oracle recommends migrating to Oracle Fusion since it's a hot product now. e-Business Suite may soon be sunsetted and has an outdated UI, with few upgrades. In contrast, Oracle Fusion offers modern features, such as AI, cloud-based applications, and customization options like Redwood features. Oracle Fusion AI chatbots are embedded, benefiting projects.

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.

Quotes from Members

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

Pros

"We use the solution for our customer's web applications."

"The solution is easy to use and connects with Microsoft."

"This is definitely a stable solution."

"The solution is very simple to use and easy to deploy."

"The solution is very easy to use and offers a quick deployment."

"IIS's best features are its management console and stability."

"The most valuable feature of the solution is that it is easy to use and easy to understand."

"We use Windows Server only for Eggplant Manager."

More IIS pros

"It is really good in terms of features, and it is stable."

"The most valuable feature is the structure of the product. We use Oracle Fusion Middleware to manage the Oracle database. Registered users can go to each product if sign-on credentials match each user's identical framework."

"The solution is extendable so you can start with two cores and add more at any time."

"Data integrity."

"The initial setup is easy. There are many self-tutorial videos are on the Internet, and then the Oracle documents are self-explanatory."

"The most valuable features are Oracle Unified Directory and unified identity access management."

"Oracle recommends moving to Oracle Fusion as they are constantly releasing new AI, modern, web-based, and cloud-based features with updated UI. With Redwood customization and AI chatbots embedded, Oracle Fusion stands ahead of older systems."

"The most valuable features are the pre-built connectors between Oracle applications, which allow quick integration. I also appreciate the fast deployment of components. Oracle Fusion Middleware's key benefit is enabling real-time data transfer between applications."

More Oracle Fusion Middleware pros

"Oracle WebLogic Server is secure."

"It has helped us to have different clusters within different servers, which allows us to identify hacker attacks."

"The only difference is that Weblogic is lighter and consumes less memory."

"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."

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

"WebLogic is reliable, and it's easy to use for development."

"Another valuable feature is the ability to automate tasks through scripts, making our environment highly efficient."

"We've got the support we require. If ever there is an issue, can just call on Oracle and they will assist us."

More Oracle WebLogic Server pros

Cons

"The areas of this solution that need improvement are monitoring, debugging, and troubleshooting."

"The user interface could be improved."

"If Microsoft IIS could work well with AppOptics or things like PHP, Python, and other custom languages that run on the webserver, it would be ideal. I think there are cases where people need to use Apache instead of IIS when IIS doesn't work well with other web languages."

"The visibility feature of the product is an area with certain shortcomings where improvements are required."

"IIS could improve by Microsoft Windows improving the update services. We would like to be able to update all systems that are connected. The WSA service has to be in good order to accomplish this."

"Sometimes if you are using IIS in large-scale scenarios, meaning that if you are deploying an application within IIS service and you are expecting a large number of users to use this application, you can sometimes find some problems, meaning that the service can shut down by itself unexpectedly if you don't configure your IIS with the correct configuration that can handle this number of users."

"The scalability depends on how you have set it up. If you're running IIS on a single server, it might not be as capable as if you are on many in a cluster or with load balancing and so on."

"I would like to see NLB features in IIS."

More IIS cons

"One thing that I would like to see is if this product can be containerized. We are moving away from virtual servers and moving more towards containerization to be able to quickly set up environments or have the flexibility of scaling them. It would be good if it can be containerized, and it works well in containerized platforms."

"I would rate the stability a nine out of ten because we did have multiple breakdowns and crashes."

"Oracle rapidly releases new features, and I may not be ready to adopt them."

"For improvements, I think Oracle Fusion Middleware could be better at connecting to third-party applications. While it works well with Oracle products, it's more limited to non-Oracle systems than other middleware solutions like MuleSoft."

"An improvement for Oracle's Fusion Middleware could definitely be found in the SOA component. It's a heavyweight container and, if you ask me, if a product is available as a docker image where we can easily port it in to another Kubernetes platform, that would be perfect. But as for the current situation in the market, nobody is really willing to deploy this on premises."

"The documentation might not be good enough for new users."

"There could be improvements in the installation and integration parts of Oracle Fusion Middleware. The guides often have errors, such as web scripting issues, and can be difficult to follow."

More Oracle Fusion Middleware cons

"There are always ways to improve. But it's getting better every time, with every new release, and every new patch, it's getting better."

"The logs consultant, since it tends to be more in the server, we do need complete consult logs for a lot of different files."

"The pricing is a little bit higher compared to other products."

"This is a complex application."

"In the future, I would like to see better support for the REST interface."

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

"They should improve the solution's garbage collection feature."

"In terms of what could be improved, maybe something related to the processes automation or starting and stopping the processes, because often WebLogic comes with something called Node Manager. Node Manager needs to be configured and administrated manually."

More IIS pricing and cost advice

"We pay annually for the solution."

"My advice is to buy the basic modules first, gain the most benefit from them, then buy the advanced modules."

"The solution is quite expensive so is only used by larger organizations."

"The solution is expensive so pricing is rated a six out of ten."

"The licensing costs are reasonable."

"The tool is best suited for large companies due to high licensing costs."

"The pricing is moderate. It's fine."

"It is expensive. We are looking for a cheaper solution."

"The tool's pricing is yearly."

"Its high expense is a significant drawback"

"Fees are paid on a yearly basis."

"I would not compare WebSphere and WebLogic because both servers are really good. The only difference is that Weblogic is lighter and consumes less memory."

"The licensing of the product is expensive"

"The solution’s pricing is affordable."

"As Oracle WebLogic Server is a product from Oracle, it is bound to be an expensive solution. My company needs to make annual payments towards the licensing costs attached to the product."

"The licensing fees are annual and depend on the model."
