Which two are advantages of using WLS JMS instead of using a third-party JMS Provider (Tibco, Sonic, etc.) ?

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 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:

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 ?
