Your organization is using a Multi data source (MDS) on WebLogic Server to support applications connecting to an Oracle RAC database. You have been tasked with configuring a new callback handler for the MDS.
Which two statements are true concerning related MDS options and behavior? (Choose two.)

  1. Callback handlers are optional when using the Failover MDS Algorithm.
  2. If the Failover Callback Handler attribute is set on the MDS, the Test Frequency attribute is no longer used.
  3. Callback handlers are called for both failover and failback decisions.
  4. You can register only one callback handler for each WebLogic server.

Answer(s): C,D

Explanation:

C: A callback handler used to control the failover and failback within a multi data source must include an implementation of the weblogic.jdbc.extensions.ConnectionPoolFailoverCallback interface.
D: You can register a callback handler with WebLogic Server that controls when a multi data source with the Failover algorithm fails over connection requests from one JDBC data source in the multi data source to the next data source in the list.
Incorrect Answers:
B: Frequency of these tests is controlled by the Test Frequency Seconds attribute of the multi source. The default value for Test Frequency is 120 seconds, so if you do not specifically set a value for the option, the multi data source will test disabled data sources every 120 seconds.

You are managing and monitoring durable subscribers for your JMS topics to ensure that all the subscribers would receive persistent messages.
However, JMS connections are currently restricted, so only one connection with the same client ID could exist in the scope of your cluster.
On which page of the Administration Console can you set Client ID Policy to unrestricted in order to lift this restriction? (Choose the best answer.)

  1. Topic > Monitoring > Durable Subscribers
  2. Connection Factory > Configuration > Client
  3. Topic > Configuration > Thresholds and Quotas
  4. Topic > Configuration > Overrides
  5. Topic > Configuration > Durable Subscribers
  6. JMS Server > Configuration > Durable Subscribers

Answer(s): B

Explanation:

You can find help on Client ID Policy configuration through the following path:
OTN Home > Oracle WebLogic Server 12.1.1.0 Documentation > Administration Console Online Help > JMS Connection Factory: Configuration: Client

Examine the domain diagram:


What is the correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04? (Choose the best answer.)

  1. /Servers/server04/Log/server04
  2. /server04/log/rotation
  3. /Cluster01/server04/log
  4. /Machine02/server04/log
  5. /Logs/server04
  6. /TestDomain/server04/log
  7. /server04/log

Answer(s): D

Explanation:

By default, the rotated files are stored in the same directory where the log file is stored.
The server log file is located on the computer that hosts the server instance. By default, the server log file is located below the server instance's root directory: root-directory\server-name\server-name.log. https://docs.oracle.com/cd/E28280_01/web.1111/e13739/config_logs.htm#WLLOG139



Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)

  1. Consensus leasing
  2. Database leasing with no pre and post migration scripts
  3. Database leasing with pre and post migration scripts
  4. Synchronous leasing

Answer(s): A,C

Explanation:

When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:
* Consensus leasing Node Manager must be running on every machine hosting managed servers within the cluster.
* Database leasing Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required.
