You now attempt to use the Administration Console web application to make a dynamic modification to that parameter. Which statement is true? (Choose the best answer.)
Respuesta
  • A new deployment plan will be generated and saved at the indicated location.
  • The modification attempt will fail because there is no existing deployment plan associated with the application.
  • A new skeleton plan.xml will be generated if a plan folder is detected with the deployed application.
  • The modification attempt will fail because there is no deployment descriptor included within the application.

You have a versioned application deployed in your production environment. You have been asked to troubleshoot why the most recent production redeployment appeared to allow the older version to retire too quickly. In this case, the application had active RMI clients, but their subsequent calls were directed to the newer version immediately rather than waiting for the expected five minutes defined by the retirement timeout argument. The script command was: java weblogic.Deployer -adminurl http://localhost:7001 -user weblogic -password Welcome1 -redeploy -name myDeployment -source /myDeployments/myApplication/appX -retiretimeout 300 You expected the older version to remain active (when there are active RMI clients) for five minutes after executing the production redeployment.

Your WebLogic domain is experiencing a problem. You want to use the WebLogic Diagnostic Framework (WLDF) to diagnose the problem. You have a support case open with Oracle Support, and they have requested a diagnostic image of your server that is experiencing the problem. The problem is not predictable or reproducible on-demand, but you noticed that the number of requests waiting to execute increases dramatically when the problem does occur. The problem also seems to occur at any time of the day or night. How would you approach reliably capturing a diagnostic image that contains data that is relevant to the problem that is occurring?
Respuesta
  • Configure WebLogic overload protection to automatically trigger a diagnostic image when the number of requests waiting to execute exceeds a certain threshold.
  • Configure a WLDF watch that triggers a diagnostic image action when the number of requests waiting to execute exceeds a certain threshold.
  • Manually monitor the number of requests waiting to execute and create a diagnostic image when you see the number of requests waiting to execute exceeds a certain threshold.

Review this scenario of an application running on a storage-disabled, managed Coherence server that uses a Coherence two-tier near cache: * Cache data is already written to the distributed cache. * There is a local near cache configured on the application side (storage-disabled node). * Application requests the data from Coherence twice. Assuming this is the server's first access of this data from the cache, how many network round trips between Coherence cluster instances take place in total? (Choose the best answer.)

Pregunta 110

Pregunta
Poor ventilation and cooling in and around the machine that hosts your administration server and a clustered managed server causes a local hard drive failure and thus both servers crash as well. This is the first time this crash has occurred in production but an automatic Whole Server Migration kicks in as expected. The clustered server migrates to a machine on which it has never run before, and for that reason the server cannot be started on this new machine. Which action could have helped to launch this migrated clustered server? (Choose the best answer.)
Respuesta
  • Shut down and relaunch the Node Manager.
  • Copy the Node Manager security files to the new machine that hosts your migrated server.
  • irst restart the Administration Server, remove this managed server from the cluster, restart it manually, and then target it back to the cluster.
  • Ensure that the Administration Server is up when the server migration is being performed.
  • Use a shared disk/NFS for all the migratable servers in the cluster.
