What information is needed in the process of creating a patch template for WLS Domain?

A. one or more patches to apply

B. the domain target

C. stage directory (if not already staged)

D. WLS Domain Administrator credentials, and Host credentials

E. Patch Plan

What is the difference between Entry Processors and Aggregators?

A. Entry Processors require a key or a set of keys, whereas Aggregators require filters.

B. Entry Processors can skip the network by executing against near caches directly, whereas Aggregators must execute on storage members.

C. Entry Processors are better suited to Map-Reduce operations than Aggregators.

D. Aggregators are optimized for read-only access, whereas Entry Processors can modify cacheentries.

Which system property is used to customize a Coherence deployment configuration for different environments?

A. tangosol.coherence.cacheconfig

B. tangosol.coherence.site

C. tangosol.coherence.management

D. tangosol.coherence.override

When an object placed into a cache implements the Java Runnable interface, Coherence will _______________.

A. immediately schedule it to be an on the service thread of the cache in which it was placed

B. do nothing; Coherence does not differentiate between types of value objects

C. ultimately attempt to run the object on a free worker thread associated with the service of the cache in which the object was placed

D. hand the object over to the Invocation service to invoke the run method

How would you create an SLA based on the "JVM Runtime Up" metric for a specific WLS server?

A. Deploy JVM Diagnostics and set a threshold on the JVMD agent up time.

B. Create a Service target that uses the WLS Domain as its system, and the JVM Runtime as itsperformance metric. Configure SLA by using that metric.

C. Define a threshold on the metric on the All Metrics page, and define a rule to create an Event for that incident. Define an SLA on the count of Incidents.

D. You cannot create an SLA on JVM-related metrics.

You are using Coherence to store state data that gets read frequently and updated only occasionally. Only 100 or so clients are logged in at any time, and state data is retrieved at login. You are running out of physical memory on the cache server tier, but CPU and network utilization is low. You have 100 GB Solid-State Drives on every system, including clients. You would also like to provide faster access to state data for logged-in users.

Which configuration should you use for your system?

A. Configure Elastic Data on your clients with a near cache.

B. Configure a near cache on your client and a RAM Journal on your cache servers.

C. Configure a near cache on your client and a Flash Journal on your cache servers.

D. Because near caching does not work with Elastic Data, configure a near cache and an eviction policy on the cache servers.

The performance of your query is very slow.

Which two actions would you take to diagnose potential bottlenecks? (Choose two.)

A. Check that indexes are registered against the fields being queried.

B. Monitor the task execution time.

C. Use the QueryRecorder to see the query Trace and Explain plan.

D. Check that indexes are cached against the fields being queried.

E. Monitor the task performance time.

Which statement about JRockit Discovery Protocol (JDP) is true?

A. JDP enables network auto discovery of JVMs.

B. JDP is a subset of HTTP.

C. JDP can be used by application to exchange serialized data between JVMs.

D. JDP was initially introduced in the HotSpot VM 1.5.

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. Near Cache

B. Entry Processors

C. Transaction Framework D. off-heap storage
