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:-FlightRecorderB:* 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 codeThe 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 systemEnables capture based on system state, event capture during event; no need to replicateWatch for stuck thread count, heap size increase, available memory, etc.Set up notifications: capture WLDF imageDiagnostic image capture spurs JFR file generation; JFR file included in diagnostic imageIncludes full JFR data from all event generatorsNote:* 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.Reference: Oracle Fusion Middleware Performance and Tuning for Oracle WebLogic Server, Tuning WebLogic Diagnostic Framework and JRockit FlightRecorder Integration -Reference: JRockit Flight Recorder & WebLogic Diagnostic FrameWork (WLDF) Integration

* Oracle GoldenGateOracle GoldenGate is Oracles 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 GuardOracle 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 OracleGoldenGate replication technology to move DR state information across data centers. Oracles 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.

C:* A WebLogic Messaging Bridge communicates with the configured source and target bridge destinations. For each mapping of a source destination to a target destination, you must configure a messaging bridge instance. Each messaging bridge instance defines the source and target destination for the mapping, a message filtering selector, a QOS, transaction semantics, and various reconnection parameters.Note:* In your JMS Foreign Server configuration:/ Specify oracle.jms.AQjmsInitialContextFactory as the JNDI Initial Context Factory./ Configure the JDBC data sources needed for your application environment.

Note:* Apache Maven is a software tool for building and managing Java-based projects. WebLogic Server provides support for Maven through the provisioning of plug- ins that enable you to perform various operations on WebLogic Server from within a Maven environment.* Continuous Integration is a software engineering practice which attempts to improve quality and reduce time to deliver software by applying small, frequent quality control efforts. It is characterized by these key practices:Use of a version control system -All developers commit to the HEAD (main code line) every dayThe product is built on every commitThe build must be automated and fastAutomated deployment to a production-like environmentAutomated testing -Results of all builds are published (so everyone can see who broke the build)Deliverables are easily available (for developers, testers, other stakeholders)

Note:* The FilteringClassLoader provides a mechanism for you to configure deployment descriptors to explicitly specify that certain packages should always be loaded from the application, rather than being loaded by the system classloader. This allows you to use alternate versions of applications such as Xerces and Ant.* To configure the FilteringClassLoader to specify a certain package is loaded from an application, add a prefer-application-packages descriptor element to the weblogic-application.xml which details the list of packages to be loaded from the application. The following example specifies that org.apache.log4j.* and antlr.* packages are loaded from the application, not the system classloader:<prefer-application-packages><package-name>org.apache.log4j.*</package-name><package-name>antlr.*</package-name></prefer-application-packages>Reference: Understanding WebLogic Server Application Classloading

The WebLogic Server Management Pack EE greatly improves application performance by providing unique functionality to automatically detect performance bottlenecks; quickly diagnose these performance problems, and identify their root cause. Key application performance management features of the pack include the following:* (A) Manage multiple farms and WebLogic Domains centrally* Monitor Oracle Coherence Cluster including all nodes within a cluster, all caches, services, connection managers and connections* Monitor middleware availability and performance out-of-box; track such data historically, and receive notifications of potential problems* Obtain real-time, in-depth JVM diagnostics without instrumentation overhead* Trace transactions across containers as well as to the database* (E) Analyze call paths and dependencies via graphical, architecture views* (E) Automatically discover and model dependencies between Java components, frameworks, and web servicesReference: Weblogic Server Management Pack Enterprise Edition

Note:** When to Use Work ManagersFollowing are guildelines to help you determine when you might want to use Work Managers to customize thread management:/ The default fair share is not sufficient.This usually ocurrs in situations where one application needs to be given higher priority over another./ A response time goal is required./ A minimum thread constraint needs to be specified to avoid server deadlock

C: Message Unit-of-Order is a WebLogic Server value-added feature that enables a stand-alone message producer, or a group of producers acting as one, to group messages into a single unit with respect to the processing order. This single unit is called a Unit-of-Order and requires that all messages from that unit be processed sequentially in the order they were created.D Transactions required for parallel processing.Incorrect:A: Many applications need an even more restricted notion of a group than provided by the Message Unit-of-Order (UOO) feature. If this is the case for your applications, WebLogic JMS provides the Unit-of-Work (UOW) Message Groups, which allows applications to send JMS messages, identifying some of them as a group and allowing a JMS consumer to process them as such. For example, an JMS producer can designate a set of messages that need to be delivered to a single client without interruption, so that the messages can be processed as a unit. Further, the client will not be blocked waiting for the completion of one unit when there is another unit that is already complete.Note:* WebLogic JMS defines two default connection factories, which you can look up using the following JNDI names: weblogic.jms.ConnectionFactory weblogic.jms.XAConnectionFactoryReference: Using Message Unit-of-Order
