Weblogic Vs. Websphere

Neither WebSphere nor WebLogic is a single product. Both servers represent part of a family of related products, and a user who purchases WebSphere or WebLogic will most likely also use the other products within the family. WebSphere and WebLogic are both enterprise servers, and several similarities and differences exists between these products.


IBM’s WebSphere and Oracle’s WebLogic are both scalable servers that use Java. Both companies also classify these servers as high-performance, although WebLogic has long been considered the industry standard According to a white paper by Crimson Consulting Group, a marketing consultancy firm, WebLogic generally offers better support and documentation. However, the group also states that the IBM name brand makes WebSphere the preferable server for many users and developers.

Product Structure

On the most basic level, WebLogic and WebSphere allow users to create applications and integrate those applications with other programs. The greater family of related products is often referred to as “application and integration middleware.” Both IBM and Oracle include a long list of products within these families. IBM takes this a step further and also categorizes these related products according to specific capabilities and what industry the products serve.

Basic Differences

According to Crimson Consulting Group’s white paper comparing WebSphere and WebLogic, a common user complaint about WebSphere is that the server contains several bugs and operates at slow speeds. WebLogic, on the other hand, functions at faster speeds and does not have as many user-reported problems. Additionally, the white paper states that WebLogic is more expensive than WebSphere, and organizations running IBM hardware typically find WebSphere offers better compatibility with existing systems.

Configuration Differences

WebSphere has several compatibility issues making this server more difficult to install and configure, states the Crimson Consulting Group’s white paper. To some extent WebLogic eliminates these compatibility issues by using a separate domain for each deployed application. This results in the ability to make configuration changes for one application without affecting the other applications. Additionally, WebSphere’s configuration setup also creates a deployment queue that takes more time to resolve and deploy than WebLogic.
