Has worked seamlessly in complex clustered environments and supports long-term development efforts
IBM WebSphere Application Server is currently at version 9.0.5.23. In recent months, they released fix 23, as they periodically release fixes. Previously, they frequently increased versions, but now they maintain 9.0.5 with different releases. It's based on Java J2EE 7 and Java SDK 1.8. Oracle announced that 2030 will be the last year when Java SDK 1.8 will be supported. Oracle currently deploys Java 2.x in parallel, with the latest being version 25. The future of IBM WebSphere Application Server remains uncertain since it's based on Java 1.8 and Java 7. I haven't found any white papers or official documentation from IBM outlining their trajectory post-2030.

We use the solution for web services.
It would be good to enhance the schedule interface. There is no indication that lets us know if a module has stopped. Shortly speaking, each business host has color in the Production page. Meanings of colors are described in a "Legend" link on the Production page. Also, each business host either has or has no private pool (processes that work with its queues). When we stop a business host by scheduling, its private processes are killed (if they exist). Such a situation is not expressed in changing business host color. The only way to check if a business host is stopped by scheduling is to check its processes presence.

Quotes from Members

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

Pros

"IBM WAS is extremely scalable. It is easy to add additional servers and to divide the load over servers in all kinds of ways."
"I would say that the clustering, achieved by using the deployment manager, is valuable, as there is a load balancing feature that uses different nodes, handled by the deployment manager, and this functionality helps with the load balancing of applications."
"The solution is very stable and robust."
"The most valuable feature of this solution is Portal Virtualization."
"I would not compare WebSphere and WebLogic because both servers are really good."
"It has good stability of the application server in the long term compared to other solutions."
"We needed this type of integration and WebShepere is the best tool for it."
"We have about 3,000 users concurrently using this application, and it has achieved more than 99.9% up time which has resulted in increased productivity and efficiency."
"The InterSystems technical support (WRC) is perfect and highly qualified."
 

Cons

"I think in some moments, the security was a little bit more complex to configure when it was delegated to other systems, making it an area where improvements are required."
"Its price is a bit expensive. They should improve its price to compete with other applications that are out there, which we are also exploring."
"Based on the field and based on the build that was provided, we've noticed a lot of constraints in terms of the performance now."
"WebSphere is very cumbersome and not user-friendly."
"The support could be a bit more responsive."
"In the next release of this solution, I would like to see support for the Arabic language."
"WebSphere is very cumbersome and not user-friendly. It used to have its own JVM, which presented challenges such as different architecture and memory leaks."
"The solution consumes hardware."
"It would be good to enhance the schedule interface."
 

Pricing and Cost Advice

"Room for improvement would only be in the licensing. As with all IBM products the licensing can be complex and expensive. Bargain well and try to get as much discount as possible. Discounts of 85% are possible. Without the discount, I think the product is overrated."
"The solution is quite expensive."
"It is very expensive."
"We used to pay about $100,000-$120,000 US or somewhere around there. That was a bit cost-prohibitive for us to continue."
"The price of this product is higher than that of competitors."
"I don't remember the price, but there are no additional costs."
"The price of IBM WebSphere Application Server could be less expensive and there is an annual license required for this solution."
"The licensing cost is 1,000 of euros for a 30-year table."
