Oracle Oracle Certifications 1Z0-599 Questions & Answers

• Question 61:

  A customer has a development environment that uses the auto-deployment feature. The customer claims the application is not redeployed even if the new version is copied to an application subdirectory. Which two parameters of the configuration should you check?

  A. Check if archive file in the compressed version has a new REDEPLOY file.

  B. If server was started in the Development Mode. Auto-deployment is not supported in production mode.

  C. If the application includes an EJB 3 module. Auto-deployment is not supported for EJBs.

  D. You change JVM from HotSpot to JRockit. Auto-deployment is not supported in HotSpot auto deployment.

  E. If the domain is a single-server domain. Auto-deployment is not supported in multiserver domains.

  Correct Answer: BE

  Auto-deployment is intended for use with a single server target in a development environment.

  Note:

  *

  If auto-deployment is enabled, when an application is copied into the \autodeploy directory of the Administration Server, the Administration Server detects the presence of the new application and deploys it automatically (if the Administration Server is running). If WebLogic Server is not running when you copy the application to the \autodeploy directory, the application is deployed the next time the WebLogic Server Administration Server is started. Auto-deployment deploys only to the Administration Server.

  *

  Limitations of Auto-Deployment

  Auto-deployed applications are very convenient in a development environment, but there are some limitations: There is no configuration in config.xml for an auto-deployed application. Therefore, in the Administration Console, there are no notes or target pages associated with an auto-deployed application because there is no backing configuration for that information.

  You cannot associate an auto-deployed application with a deployment plan since auto-deployed applications do not support any configuration operations which would be reflected in a deployment plan.

  You cannot set up security policies or roles for auto-deployed applications.

  You cannot undeploy or redeploy auto-deployed applications using WebLogic Server tools.

• Question 62:

  Which new key architectural element introduced in WebLogic Server l2c should you take advantage of when designing Disaster Recovery Centers with active - passive mode?

  A. MAN Clusters, because they would allow you to synchronously replicate state in low latency networks

  B. WAN Clusters, because they would allow you to asynchronously replicate state in nonlow latency networks.

  C. Transaction Log in the database, because you could avoid synchronizing two replication technologies (database and file)

  D. Data Guard, because it is the most effective way to replicate a state across locations

  E. GoldenGate, because it is the most effective way to replicate a state across locations

  Correct Answer: E

  *

  Oracle GoldenGate Oracle GoldenGate is Oracle's strategic product for data distribution and data integration. It is a highperformance software application that uses log-based bidirectional data replication for real- time capture, transformation, routing, and delivery of database transactions across heterogeneous systems.

  Note:

  *

  Oracle Active Data Guard Oracle Active Data Guard 11g is an option of Oracle Database Enterprise Edition that extends basic Data Guard functionality. It allows a physical standby database to be open as read-only while changes are applied to it from the primary database. This increases performance and return on investment by offloading ad-hoc queries, Web-based access, reporting, and backups from the primary database while also providing disaster protection.

  *

  Disaster recovery (DR) procedures ensure rapid recovery or continuation of a technology infrastructure after a natural or human-induced disaster. Oracle WebLogic Server 12c supports advanced disaster recovery and business continuity. Organizations can store transaction logs in an Oracle database instead of a file system, providing a highly available storage mechanism to improve the speed and reliability of disaster recovery operations. This permits them to utilize Oracle Active Data Guard or Oracle GoldenGate replication technology to move DR state information across data centers. Oracle's enhanced DR architecture enables more effective recovery scenarios. Support for Oracle Exalogic and Oracle Exadata engineered systems ensures tremendous scalability for IT operations of any size.

  *

  Oracle WebLogic Server 12c places transaction logs on the database tier to improve the speed, reliability and availability of disaster recovery operations.

  

• Question 63:

  A. Oracle WebLogic Domain Upgrade tool

  B. Smart Update

  C. Smart Upgrade

  D. No tool required, just install WebLogic 12c, update the domain to point to the new WebLogic installation and start your domain.

  E. JDeveloper

  Correct Answer: D

  Note:

  You can use the 12.1.1 WebLogic Upgrade Wizard to upgrade domains created in WebLogic Server 8.1.

  You can also use the WebLogic Upgrade Wizard to upgrade a WebLogic domain created in WebLogic

  Server 9.x or 10.x to 12.1.1, but this is optional.

• Question 64:

  You completed the development of a new application and want to create a new domain in a new

  environment for functional testing. You want to have the same settings for your new domain as your old

  domain, with the option of changing the configuration in the new target environment.

  Which two actions should you execute?

  A. Use the introspect () command in WLST to gather the configuration information from the original domain.

  B. Use pack/unpack to transfer the domain from one machine to another.

  C. Create a domain template from the original domain using the Domain Template Builder and use the Configuration Wizard to create a new domain from the template.

  D. Use the Admin Console of the original domain to create a domain template from the original domain and use the Configuration Wizard to create a new domain from the template.

  Correct Answer: C

  Using the Domain Template Builder to Create Domain Templates

  To create a domain, start the Configuration Wizard and choose a domain configuration template.

• Question 65:

  You want to capture WebLogic internal events correlated with JVM events for viewing offline. What three actions must you take to enable this within WebLogic?

  A. Run WebLogic in a JRockit JVM and ensure the Flight Recorder is enabled.

  B. Configure the WebLogic Diagnostic Framework Event Volume to Low, Medium, or High depending on the type of events you want to capture.

  C. Configure the WebLogic Diagnostic Framework bridge to send events to the JRockit Flight Recording.

  D. Take a dump from the default recording or create a new recording for the time period you want to capture.

  Correct Answer: ABD

  A: You can enable JFR at runtime to take JRA recordings from the JRockit Management Console. You also have the option of turning off the JFR and recordings at the JRockit JVM level from the java command line using:

  $ java -XX:-FlightRecorder

  B:

  *

  In most environments, there is little performance impact when the Diagnostic Volume is set to Low and

  the most performance impact if Diagnostic Volume is set to High. The volume of diagnostic data produced

  by WebLogic Server needs to be weighed against potential performance loss.

  *

  WLDF provides the Diagnostic Volume attribute to set the amount of code coverage that is enabled and

  the amount of data provided in the events that are generated for the covered code The following code

  example sets the volume to Medium:

  . . .

  connect()

  edit()

  startEdit()

  cd("Servers/myserver")

  cd("ServerDiagnosticConfig")

  cd("myserver")

  cmo.setWLDFDiagnosticVolume("Medium")

  save()

  activate()

  D: Integrated with the WebLogic Diagnostic Image and Watch and Notification system

  · Enables capture based on system state, event capture during event; no need to replicate · Watch for

  stuck thread count, heap size increase, available memory, etc.

  · Set up notifications: capture WLDF image

  · Diagnostic image capture spurs JFR file generation; JFR file included in diagnostic image · Includes full

  JFR data from all event generators

  Note:

  * WebLogic Diagnostic Framework (WLDF) provides specific integration points with JRockit Mission Control Flight Recorder. WebLogic Server events are propagated to the Flight Recorder for inclusion in a common data set for runtime or post-incident analysis.

• Question 66:

  Which two statements are true regarding the WebLogic domain?

  A. A WebLogic domain can have more than one Administration server.

  B. A WebLogic domain has at least one WebLogic server.

  C. A WebLogic domain can have at the most one cluster.

  D. A WebLogic domain can cross multiple physical machines.

  E. Each WebLogic domain is associated with a different Node Manager.

  Correct Answer: BD

  B: A domain consists of one or more WebLogic Server instances (and their associated resources) that you manage with a single Administration Server.

  D: In a domain, server instances other than the Administration Server are referred to as Managed Servers. Managed Servers host the components and associated resources that constitute your applications.

  Incorrect:

  Not A: Each WebLogic Server domain must have one server instance that acts as the Administration

  Server.

  Not C: A domain can include multiple WebLogic Server clusters and non-clustered WebLogic Server

  instances.

  Not E: A Node Manager process is not associated with a specific WebLogic domain but with a machine.

  You can use the same Node Manager process to control server instances in any WebLogic Server

  domain, as long as the server instances reside on the same machine as the Node Manager process. Node

  Manager must run on each computer that hosts WebLogic Server instances--whether Administration

  Server or Managed Server--that you want to control with Node Manager.

• Question 67:

  What does the Fast Connection Failover feature of Active GridLink for RAC provide?

  A. instant notification of a RAC node failure so applications never have to retry a transaction that was sent to a node that failed during the transaction

  B. near-instant notification of the failure of a RAC node failure that minimizes the possibility connection to a failed node being provided to an application

  C. application level notification of a failed RAC node such that an application can retry a transaction if required

  D. faster failover for Multi Datasources

  E. guaranteed transaction high availability when interacting with an Oracle RAC Database

  Correct Answer: B

  *

  WebLogic Server supports Fast Connection Failover, a Oracle feature which provides an application independent method to implement RAC event notifications, such a detection and cleanup of invalid connections, load balancing of available connections, and work redistribution on active RAC instances.

  *

  A GridLink data source uses Fast Connection Failover and responds to Oracle RAC events using ONS. This ensures that the connection pool in the GridLink data source contains valid connections (including reserved connections) without the need to poll and test connections

• Question 68:

  What are the two proper locations of deployment descriptors files inside of archives deployed to WebLogic?

  A. the WEB-INF subdirectory for a WAR file

  B. the META-INF subdirectory for an EAR file, or EJB-JAR

  C. the DD-INF subdirectory

  D. the root of archive

  E. any searchable location

  Correct Answer: AB

  A:

  *

  The WEB-INF directory contains the deployment descriptors for the Web application (web.xml and weblogic.xml) and two subdirectories for storing compiled Java classes and library JAR files.

  *

  Web Application - WEB-INF/web.xml ( WEB-INF/weblogic.xml ) The WEB-INF directory is a vital component of your web application. Web application wont run without it.It contains a heirarcy in which you'll find the necessary configuration information for your web application, and all the class files for your servlets and classes that are called up by your JSPs.

  WEB-INF folder contains all the class files for your servlets and classes that are called up by your JSPs

  B:

  Enterprise Application - META-INF/application.xml (META-INF/weblogic-application.xml) and META-INF/

  ejb-jar.xml ( META-INF/weblogic-ejb-jar.xml ) Generally comprises of EJBs. Bussiness Tier of an

  application and EJB basically handels the Bussiness logic of application (distributed objects)

  META-INF/application.xml containes Mappings and security roles etc.whereas META-INF/ejb- jar.xml containes ejb classes , session beans mapping etc.,

  The META-INF directory is related to .jar files, It contains the manifest file which has list of jars.

  A context-root setting in application.xml takes precedence over context-root setting in weblogic.xml (The context root of a web application determines which URLs weblogic will delegate to your web application.

  Note:

  * Deployment descriptors are xml documents that describe runtime behaviour for the deployment unit. The XML file contains information such as the context root of the web application and the mapping of the portable names of an application's resources to the application Server's resources

• Question 69:

  An application is using WebLogic JMS Store and Forward to forward messages from a local JMS queue a remote WebLogic JMS destination. You need to determine if the messages are being sent from the local Weblogic Server. Where do you find information and metrics about Store and Forward components in the WebLogic Admin Console?

  A. JMS Persistent Store

  B. JMS Server

  C. JMS Distributed Destination

  D. JMS Store and Forward

  E. Automatic Service Migration

  Correct Answer: A

  Note:

  * Persistent messages are saved in the persistent store on the sending side until they are successfully forwarded to and acknowledged by the receiving side.

• Question 70:

  You want to use WLST to view metrics for a running domain. Which command should you issue to navigate through the Mbean hierarchy containing the metrics?

  A. runtime ()

  B. runtimeMbeanServer ()

  C. connectRuntime ()

  D. beginRuntime ()

  E. serverRuntime ()

  Correct Answer: E

  Similar to the configuration information, WebLogic Server runtime MBeans are arranged in a hierarchical data structure. When connected to an Administration Server, you access the runtime MBean hierarchy by entering the serverRuntime or the domainRuntime command. The serverRuntime command places WLST at the root of the server runtime management objects, ServerRuntimeMBean; the domainRuntime command, at the root of the domain-wide runtime management objects, DomainRuntimeMBean.
