    18. Question 18. Differentiate Between The Horizontal And Vertical Cluster?

      Answer :

      General, two types of the cluster are done. The horizontal cluster refers to the cluster which can be done between a huge number of multiple nodes and all the servers found in the cell. On the other hand, the vertical cluster is mainly done between the members I'd the same bode and server. 

    19. Question 19. Define Connecting Pool?

      Answer :

      The connecting pool is basically the cache of various connections of the database and is maintained in such a way that can be used again the near future. Such requests for database caching are very frequent and common in WebSphere. However, when all the connections get occupied then a whole new connection is made and gets automatically added to the pool. 

    20. Question 20. Differentiate Between Web Logic And Websphere?

      Answer :

      Web logic includes various attributes which are default transactions like for example supports. However, WebSphere doesn't include any such type of default transactions. The focus on creativity and the integration are mainly done by WebSphere. Web services are also maintained peppy by it. Hence, the performance by WebSphere is much nicer and better than that of web logic. In fact, integration and the management of transactions are also better than web logic.
