Question 13

A system administrator is tasked with monitoring the overall health of the WebSphere environment to be able to tune the environment properly. Specifically, the administrator was asked to:
Which PMI modules can the administrator examine to obtain this data?

A. Number of requests, Java virtual memory, Average response time

B. Number of requests, Average response time, Web server thread pools

C. Average response time, Java virtual memory, Number of Live HTTP Sessions

D. Average response time, Web server thread pools, Number of Live HTTP Sessions

Correct Answer:C
Monitoring overall system health. To monitor overall system health, monitor the following statistics at a minimum:

Question 14

A system administrator was asked by the development team to inform them of any warning message which contains a string “Connection” on a WebSphere Application Server with High Performance Extensible Logging (HPEL) enabled.

A. Configure log detail levels to include filter on “Connection” string.

B. Use the Log Viewer in the administrative console with filter on “Connection” string.

C. Use the logviewer.sh or logviewer.bat command with appropriate options.

D. Use the Log Viewer in the administrative console with filter on “Connection” string and enable the “Refresh automatically” feature.

Correct Answer:C
The High Performance Extensible Logging (HPEL) facility writes to the log and trace repositories in a binary format. You can view, query and filter the repository using the LogViewer command.
logviewer.sh -monitor -includeLoggers Connection
-monitor [integer]Specifies that you want the logViewer to continuously monitor the repository and output new log record entries as they are created. You can provide an optional integer argument after this parameter to specify how often you want the LogViewer tool to query the repository for new records. By default the logViewer queries the repository for new records every 5 seconds. When used with other filtering options, only those new records that match the filter criteria are displayed.

Question 15

A system administrator has created a Jython script called globalScript.py.
What should the administrator do to ensure globalScript.py is loaded when the wsadmin shell is used?

A. Compile globalScript.py to a Java class in the bin directory.

B. Invoke wsadmin with the argument –profileName globalScript.py.

C. Modify the configureCustomProperty script to import globalScript.py.

D. Set the script profiles in the wsadmin.properties file to load globalScript.py.

Correct Answer:D
wsadmin.properties has this entry com.ibm.ws.scripting.profiles where we can add the scripting files to be loaded.

Question 16

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.

Correct Answer:A
Deleting profiles. You can delete a profile using the manageprofiles command. If the command fails, you can delete the profile using operating system commands.
Before you begin: If a node within a profile is federated to a deployment manager, before you delete the profile, stop the node and remove the node from the deployment manager.
Otherwise, an orphan node remains in the deployment manager.

Question 17

A system administrator needs to trigger a javacore only when a java,net.SocketTimeoutException is encountered in real time.
What does the administrator have to configure to trigger the javacore dump?

A. Configure the JAVA_DUMP_OPTS environment variable to capture javacore for ANYSIGNAL and all exceptions.

B. Configure an –Xdump:java Generic JVM argument on WebSphere Application Server with the filter for java.net.SocketTimeoutException.

C. Code wsadmin script to capture javacore and then execute it after the java.net.SocketTimeoutException has been encountered.

D. Use the log filter in HPEL to monitor for java.net.SocketTimeoutException and then gather a javacore dump from the Integrated Solutions Console (ISC).

Correct Answer:B
Dump agents are set up during JVM initialization. They enable you to use events occurring within the JVM, such as Garbage Collection, thread start, or JVM termination, to initiate one of four types of dump or to launch an external tool. Default dump agents are set up at JVM initialization They are sufficient for most cases, but the use of the -Xdump option on the command line allows more detailed configuration of dump agents. The total set of options and sub-options available under -Xdump is very flexible and there are many examples presented in this chapter to show this flexibility.
Example: To generate system cores:
-Xdump:system:events=user

Question 18

A newly deployed application has authorization errors when invoking EJB methods from a servlet. An additional review indicates that users are authenticated, but do not have the correct authorization.
How can a system administrator fix the issue ensuring only authorized access?

A. Using the Integrated Solutions Console (ISC), map all security roles to the special subject Everyone.

B. Using the Integrated Solutions Console (ISC), map the security roles that are still not mapped to groups in the correct user registry.

C. Edit the application using an assembly tool to add a security constraint for the servlet and reinstall the application.

D. Edit the application using an assembly tool to remove the security constraint defined for the servlet and reinstall the application.

Correct Answer:B
