A system administrator needs to configure a JDBC provider and a data source for an application in a clustered environment. The administrator also needs to copy the JDBC drivers from the database server to the application server machines.

How can the administrator meet these requirements?

A. Create a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.

B. Create a JDBC provider in the server scope and the data source in the node scope.Copy the driver to all application servers.Set the environment variable at the node level to the driver's path.

C. Create a JDBC provider in the node scope and the data source in the cell scope.Copy the driver to the deployment manager.Set the environment variable at the server level to point to the deployment manager path.

D. Create a JDBC provider in the application scope and the data source in the server scope.Copy the driver to all application server directories.Set the environment variable in each JVM to the driver's path.

A system administrator has configured a network deployment cell containing multiple nodes and global security enabled with an LDAP repository. To increase capacity, the administrator needs to add additional nodes to the cell. After adding the nodes by using both scripts and the Integrated Solutions Console (ISC), the administrator examines the System.out log for the deployment manager and notices the following message:

How can the administrator resolve this problem?

A. Disable Java 2 security.

B. Restart the deployment manager.

C. Increase the RSA token timeout value.

D. Change the number of active LTPA keys.

A performance test team was testing the capacity of concurrent users of a web application deployed on a multi-processor server. While testing 250 concurrent users, the administrator discovers connections to the database are failing.

In response, a system administrator increased the connection pool to the maximum limit which the database allows and increased the prepared statement cache size. The test passed, but the application response time was slower.

How should the system administrator tune the data source properties to improve the application response time?

A. Change connection pools purge policy.

B. Decrease connection pool reap time.

C. Decrease number of free pool partitions.

D. Decrease the prepared statement cache size.

An application deployed to a multi-node cluster is reported to have slowness and hung threads. A system administrator is asked to review the logs on each node and identify if the hung threads are a false alarm.

How can the administrator determine that the hung threads are a false alarm? Analyze the:

A. ffdc logs

B. SystemErr.log

C. SystemOut.log

D. native_stderr.log

A system administrator needs to create a cell for a test environment. The administrator uses the Profile Management Tool (PMT) to create the deployment manager profile using the advanced profile creation option and creates a custom profile using the typical profile creation option. The administrator examines the log files for the custom profile creation and sees an INSTCONFFAIL message indicating the deployment manager was not running during the custom profile creation.

How should the administrator fix this?

A. Delete the custom profile.Start the deployment manager.Create the custom profile again.

B. Start the deployment manager.Use PMT to re-create the custom profile.

C. Use the syncNode command to synchronize the node.

D. Run the addNode command to federate the custom profile.
