Question:

As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The Weblogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round –robin algorithm. 
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?

Response:

	Replace the software load balancer with a hardware load balancer.
	Tune work managers to optimize work.
	Modify the proxy server load balancing algorithm to weight based.
	Configure dynamic clusters and specify the number of server instances you anticipate at needing at peak load.
	Add a third cluster and spread existing server instances across the clusters.

Question:

A WebLogic server domain contains a dynamic cluster called “cluster1”.The cluster “cluster”1 has two dynamic managed servers “server1” and “server2”. There is a need to view the inherited attribute values for “server2”.
How do you view all attributes of “server2”.including those inherited from the server template?

Response:

	Use java weblogic.Deployer.
	You cannot, because attribute values are not inherited.
	Use WLST.
	Use WebLogic Administration console >”server” link.

Question:

You want to configure WebLogic server transactions to be recoverable when a nonclustered managed server crashes, even if that crash is caused by an unrecoverable hardware failure. You want to run the managed server on different hardware, and have it recover the transactions that were in-progress at the time of the crash.
You also want to use the default store for transaction logs.
Which statement is true?

Response:

	Before the crash ,you need to update the path to the default store for the managed server. The path should be to some shared storage location.
	This scenario is common , and so the default configuration of the default store works.
	After the crash, obtain a copy of the managed server’s default store from the administration server. Move it to the same relative location on the new hardware before starting the managed server there.
	This scenario is not possible .You must use the JDBC store to recover transactions from a crashed server.
	This scenario is not possible. You must use clustered managed servers to recover transactions from a crashed server.

Question:

You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers.
The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select “Supports Global Transactions” and One-phase commit.
Why is this configuration wrong?

Response:

	"One-Phase Commit" processes this data source last In the global transactions, if the EJB must go last, you cannot use this configuration.
	"One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.
	You must choose an XA driver when a data source participates In global transactions.
	"One' Phase Commit" always returns "ready" during phase one of the two-phase commit process’ so it is possible you will have heuristic errors in the database.

	FCF requires the use and configuration of a database server in the GridLink data source.
	You can use any Oracle Thin database driver with a GridLink data source.
	FCF is faster because it polls and tests connection, freeing the data source from these tasks.
