A customer is witnessing a lot of contention while accessing and updating a cached item.
Which feature alleviates the connection by shortening the time that the object is locked?

• A.Transaction Framework
• B.Near Cache
• C.off-heap storage
• D.Entry Processors

An application frequently requests data (from s Coherence cache configured with a cache loader) that may not be available in the underlying data source. The cost of looking up data via the cache loader is expensive in terms of time and resources.
To reduce these costs, which configuration should be used to cache the notion that an entry is not available?

• A.Modify the application to maintain a "misses" cache to keep track of the entries that were expected to be found in the other cache, but were recently not found.
• B.Modify the cache loader to maintain a "map" of entries not found, and consult this map before attempting to load an entry from the external source.
• C.This can't be achieved with Coherence.
• D.Configure a "cache-miss-scheme" on the appropriate cache.

Your application had experienced an OutOfMemoryError on one of the cache servers. You had configured the JVM to produce a heap dump when OutOfMemoryErrors occur. Your analysis of the heap dump indicates that approximately 90% of the heap is consumed by instances of com.tangosol.util.Binary.
What configuration change will reduce the number of com.tangosol.util.Binary instances?

• A.Increase the size of the thread pool for all cache services.
• B.Lower the high-unit threshold on all distributed-scheme backing maps.
• C.Increase the expiry delay on all distributed-scheme backing maps.
• D.Introduce a near cache for all partitioned caches.

What two sources can be used to provision a WLS domain? (Choose two.)

• A.Middleware Home Gold Image
• B.TAR file on network desktop
• C.WebLogic Domain Provisioning Profile
• D.TAR file on local desktop
• E.WebLogic Home Gold Image
