C: The saviour of having to type in the username and password each and every time that you start a server. A very useful little file to have, particularly if you have multiple managed servers.

By default, this appears in the Admin Servers security directory ($DOMAIN_HOME/servers/AdminServer/security) when a domain is created in development mode and is called boot.properties. The file is only created for the admin server, not for any additional servers; simply copying the security directory over is enough. The password is encrypted for the domain, so it can only be used for servers within that domain.

In production mode, the boot.properties file doesn't exist.

D: Development mode enables a WebLogic Server instance to automatically deploy and update applications that are in the domain_name/autodeploy directory (where domain_name is the name of a WebLogic Server domain). Production mode disables the auto-deployment feature and prevents any applications you place in the autodeploy directory after you switch to production mode from being deployed.

Note:

* By default, a WebLogic Server domain runs in development mode.

* You can run a WebLogic Server domain in two different modes: development and production. Only development mode allows you use the auto-deployment feature

Incorrect:

Not A: New or enhanced WebLogic 12c features include

JAVA EE 6 support all kinds of JEE6 specifications

Not C: 12c do include a new Maven plug-in

Not D: For 1.6 adapters, you can embed metadata annotations in the resource adapter class files to specify deployment information, eliminating the need to create the ra.xml file manually.

Session Affinity Policy

Web applications where a user session has back-to-back online transaction processing (OLTP) have better performance when repeated operations against the same set of records are processed by the same RAC instance. Business applications such as online shopping and online banking are typical examples of this pattern.

A GridLink data source uses the Session Affinity policy to ensure all the data base operations for a web session, including transactions, are directed to the same Oracle RAC instance of a RAC cluster.

Note:

The context is stored in the HTTP session. It is up to the application how windows (within a browser or across browsers) are mapped to HTTP sessions.

Note 2:

* GridLink Affinity

WebLogic Server GridLink affinity policies are designed to improve application performance by maximizing RAC cluster utilization. A GridLink data source monitors RAC load balancing advisories (LBAs) using the AffEnabled attribute to determine if RAC affinity is enabled for a RAC cluster. The first connection request is load balanced using Runtime Connection Load-Balancing (RCLB) and is assigned an Affinity context. All subsequent connection requests are routed to the same Oracle RAC instance using the Affinity context of the first connection until the session ends or the transaction completes.

* 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.
