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.
A system administrator is required to monitor the application server logs for heap memory issues and determine if the heap memory usage is reaching close to 70% of the maximum heap. The application server is configured with an initial heap of 256 MB and a max heap of 1 GB.
How should the administrator determine if the application server is utilizing 70% of the max allocated heap memory?
- A . Check the System logs for OutOfMemoryErrors.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
- B . Configure WebSphere Application Server to enable verbose garbage collection.Analyze the garbage collection cycles in the native logs.
- C . Configure Initial heap to be equal to the max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
- D . Configure WebSphere Application Server to increase max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
After collecting diagnostic trace from a server running under a cell, a system administrator noticed that the trace files contained sensitive information.
To avoid this issue in the future, what can the administrator do?
- A . Configure entries in the ras.rawtracelist.properties.
- B . Configure suppressSensitiveTrace in the bootstrap.properties file.
- C . Clear the “Disable logging and tracing of potentially sensitive data” checkbox.
- D . Add the entry com.ibm.websphere.logging.RawTraceList=off to the end of the trace string.
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 CXdump: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).
An EJB application posts a request message into a JMS destination and waits for a response message on a different JMS destination. To correlate the response message to the request message, the application uses the JMS correlationId of the message. The application waits up to five seconds for a response before timing out the request.
A Message Driven Bean (MDB) running on a different cluster is responsible for consuming the request message, process it and post a response message.
The destinations are defined in a Service Integration Bus (SIB) within the cell.
Intermittent timeout exceptions have occurred for the requester application.
How can a system administrator correlate and analyze the debug information from both requester and consumer applications?
- A . Enable High Performance Extensible Logging (HPEL).Use HPEL logViewer command to see debug information.
- B . Enable a diagnostic trace in both requester and consumer servers.Use the Integrated Solutions Console (ISC) to set the admin=all trace.Analyze the trace.
- C . Enable High Performance Extensible Logging (HPEL).Enable Cross Component Trace (XCT) to include request IDs in log and trace records.Use HPEL logViewer command with appropriate filters to see debug information.
- D . Using the Integrated Solutions Console (ISC), browse the request message that has timed out and look for any key application data.Search for exceptions using the key application data in both requester and consumer in native_stderr.log and native_stdout.log.
A WebSphere system administrator needs to install the Installation Manager (IM) on an unmanaged node on a host named <machine2>. The deployment manager is running on a host named <machine1>.
What step must the administrator take before submitting a job from the Integrated Solutions Console (ISC) to install the IM on <machine2>?
- A . Install a node agent on <machine2>.
- B . Install the job manager on <machine1>.
- C . Start the job manager on <machine1>.
- D . Register <machine2> as a target for job manager.
A system administrator has created a wsadmin script with several steps to install and configure an application and some resources in a WebSphere Application Server process. The script executed but the application was not installed successfully. The administrator suspects that the script has problems.
How can the administrator test and debug the script?
- A . In WebSphere Application Server Developer Tools for Eclipse, right click on the script file and select Validate from context menu.
- B . Execute the script using the wsadmin with the option Cconntype NONE and monitor the commandAssistanceJythonCommands.log file.
- C . Use WebSphere Application Server Developer Tools for Eclipse in the debug perspective connected to the server and execute the script step by step.
- D . Run the script using wsadmin with these parameters: -lang jython Cjavaoption “-Xdebug” and then execute the logViewer command with the option -listInstances
A system administrator has been asked to uninstall an application from a cluster running in a WebSphere Application Server Network Deployment cell. This application was installed from the Integrated Solutions Console (ISC). The monitored directory for the cluster is <cluster1_dir>.
What step(s) can the administrator perform to uninstall the application?
- A . Delete the application file from <cluster1_dir>.
- B . Stop the running cluster.Delete the application file from <cluster1_dir>.
- C . Stop the running cluster.Copy the application file to <cluster1_dir>.Delete the application file from <cluster1_dir>.
- D . Create a properties file to describe the deletion of the application file.Copy the properties file to <cluster1_dir>.
A system administrator runs a Jython script that creates and configures several servers and realize that the script fails before completing. Although many tasks succeeded, they are rolled back when the script fails.
Before running the script again, what can the administrator add to the script after each task so the completed tasks are committed even if other tasks fail?
- A . AdminApp.update()
- B . AdminConfig.save()
- C . AdminControl.invoke(server, ‘sync’)
- D . AdminTask.backupJobManager(‘server’)
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 CprofileName 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.
