Which two are advantages of using WLS JMS instead of using a third-party JMS Provider (Tibco, Sonic, etc.) ?
JMS subsystem of WLS shares same JVM as core WLS application server, so application avoids the overhead of message serialization/de-serialization (necessary when using a 3rd party JMS provider with WLS)

See the build instructions for managing Coherence via JMX and put the steps in order. 1. Update set-env.cmd (or set-env.sh if you are building on UNIX) to reflect your system environment. 2. Open a command shell and execute set-env.cmd (or source set-env.sh if you are building on UNIX) 3. Run ant build. 4. Deploy the jmx-console.war file found under the build directory to your application server. Be sure to start your application server JVM with the necessary Coherence Management Framework overrides. For example: -Dtangosol.coherence.management=all 5. To remove build artifacts from your file system, run 'ant clean'

You want to use te Coherence Java APIs to directly cached POJOs. Consider this snippet of code: NamedCache cache - CacheFactory.getCache("mycache"); cache.put(new Integer(I)f "hello"); cache.put(T,"hi"); cache.put(new Long(II),"hey"); This code inserts three objects into the cache. Why ?
hashCode() and equals() method for each object type is different so a different key is used
Which two statements are true about the Application Grid ?

Which Coherence caching pattern matches the sequence of events ? 1. Data is requested from cache 2. The requested data does not exist in the cache (cache miss) 3. The Coherence cache store is used to red data from the back-end persistent data source, and placed in ther cache 4. Data requested from the cache is returned to the caller
Which two functional areas does Oracle Application Grid provide ?
Identify two correct statements to complete the sentance. In a Coherence implementation, it is a best practice to implement PortableObject on all customer objects because:
it provides a more efficient serialization of the object
it allows the object to be shared across programming platforms
ABC Company has approximately 150'000 products in their catalog and wants to put these within a Coherence cache to improve performance and access times of their existing JEE application without too much change to existing code. There are a number of servlets that get the same product information multiple times within a page. There are also a number of server-based processes that run at regular intervals and also request product information many times. Products have small changes which need to be updated during the day. What would be the most appropriate caching scheme to use ?
Which interface provides the ability to aggregate values across a cluster in parallel using Filters ?
You are doing an environment assessment for a client that has invested in Oracle RAC for fault tolerance, load balancing, and scalability. The client also invested in clustered Oracle WebLogic Server. You notice that this client's environment is not integrated for active-active high availability deployment of applications. What will be your recommendation to achieve that ?
GridLink to RAC
As an architect for ABC bank, you have been tasked to improve the performance of their online balance transfer application. Due to various margers and takeovers, the bank has heterogeneous systems.
