Question 60

Question
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?
Answer
  • Configure WebLogic overload protection to automatically trigger a diagnostic image when the number of requests waiting to execute exceeds a certain threshold.

[view IMG] Assuming the next request for an HTTP session attribute is a new attribute that is not stored in a near-cache, the client's session attribute is fetched from the remaining storage-enabled server in cluster 2. Why is the session attribute retrieved from this other server's cache? (Choose the best answer.)
Image:
Preg 62 (binary/octet-stream)
Answer
  • Coherence*Web stores sessions in a distributed cache on the back end and the request fails over to the new location after partition re-balancing takes place.
  • Coherence*Web stores sessions in a replicated cache on the back end and the request fails over to the new location automatically.
  • Coherence*Web stores sessions in a shared disk cache on the back end and Coherence*Web automatically load balances requests.
  • Coherence*Web stores sessions in a cache that is backed by a database cache loader. The data is fetched from the database and placed into the cache on the new server.

Answer
  • when the onMessage() method fails to acknowledge the reception of the message
  • when messages are not being sent as part of a transaction
  • when the transaction the MDB participates in eventually fails and rolls back

  • when the onMessaqe() method of the MDB throws a Java error

Question 109

Question
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.)
Answer
  • 1
  • 3
  • 2
  • 4

Question 110

Question
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.)
Answer
  • 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.

Question 111

Question
The image below [View IMG] depicts a high-level diagram of configuration auditing within WebLogic Server. When Administrators make configuration changes to the WebLogic Server domain, those changes are sent to the audit provider for logging.
Image:
Preg 52 B (binary/octet-stream)
Answer
  • Configure the CONFIG severity level.
  • Define unique users for all administrators.
  • Configure a persistent store for log messages.
  • Define the audit message listener for audit messages,

Question 112

Question
I want to configure automatic migration of pinned services from an unhealthy server to another target in the cluster. I wish to configure consensus leasing for this purpose. Which two statements are true in this scenario? (Choose two.)
Answer
  • A high availability database must be configured to manage consensus leasing information.
  • Set the cluster "Migration Basis" policy to Consensus.
  • Set the server "Migration Basis" policy to Consensus.
  • Migratable server should be associated with a node manager.

Question 113

Question
You are asked to create a WLST script to make live updates to a domain that has its administration server running. You want your script to mimic the actions of a WebLogic administrator by using the administration console and clicking the "Lock and Edit" button.What commands would accomplish this?
Answer
  • lockDomain() followed by edit()
  • lockDomain() followed by editDomain()
  • edit() followed by startEdit()
  • clearPending() followed by lockDomain()
