46.Explain what is WebSphere edge server?

The WebSphere edge server is used to enhance the performance of web based systems. It can be used as a proxy server. There are basically four components in the web sphere they are caching proxy, content distribution, network dispatcher and application server at the edge

47.Explain how caching proxy of WebSphere on the edge server is done?

A caching proxy can be configured in forward direction or as a proxy. When user requests the content, it is cached by the edge before sending or following to the query. Page fragments arising from Servlets or JSP are cached by Edge, and the Caching process becomes Slow. Performance and scalability can be optimized by edge.

48.Mention what functionality does caching proxy server provides?

Caching server provides functionality like

• Reverse proxy and content based routing
• Integration with servlet caching and dynamic content caching

49.Mention what are the Websphere MQ programming APIs?

Websphere MQ programming APIs include

• AMI (Application Messaging Interface)

50.Mention which resource can enhance EARs support apart from shared libraries and data sources?

Class loader policy, JAAS authentication aliases and virtual host information can enhance EARs support apart from EARs support and shared libraries.

51.Mention how many ways you can deploy the application in WebSphere?

In Websphere application can be deployed in three ways

• Copy files directly to deploy application folder in websphere
• Use websphere specific ant tasks create automated scripts for deploying application
• Via administration console

52.Mention what Sync function does in Websphere?

WAS (WebServer Application Server) stores all the configuration in one central location referred as “Master Repository”. The sync ensures the configuration in both local and master repositories are same and in sync.

57.When you use migration wizard (PMT) for WebSphere Application Server 8, do you expect to have all profile services up and running again?

No, migration wizard only provides minimal function and it does not enable any services by default.

58.In a scenario where an administrator needs to migrate the entire application server profiles from v6.1 to v8 using Profile Management Tool (PMT) and he wants to keep all windows services created for these profiles, how to make sure that these windows services are kept after migration process?

Administrator must create the new profile with a services enabled before starting the wizard, and then point to that profile during the migration wizard.

59.Assume that you installed WAS 6 after WAS 8 on your server, is it then possible to migrate WAS 6 nodes to WAS 8?

No, it will not work as WAS 8 should be installed after those earlier versions.

60.What are the new capabilities in IBM Installation Manager V8?

Here is a list of new capabilities:
