Question 11

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.

  1. Configure log detail levels to include filter on "Connection" string.
  2. Use the Log Viewer in the administrative console with filter on "Connection" string.
  3. Use the logviewer.sh or logviewer.bat command with appropriate options.
  4. Use the Log Viewer in the administrative console with filter on "Connection" string and enable the "Refresh automatically" feature.

Question 12

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?

  1. Check the System logs for OutOfMemoryErrors. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
  2. Configure WebSphere Application Server to enable verbose garbage collection. Analyze the garbage collection cycles in the native logs.
  3. Configure Initial heap to be equal to the max heap. Trigger a heap dump from the Integrated Solutions Console (ISC). Analyze the heap dump.
  4. Configure WebSphere Application Server to increase max heap. Trigger a heap dump from the Integrated Solutions Console (ISC).

Question 13

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?

  1. Configure entries in the ras.rawtracelist.properties.
  2. Configure suppressSensitiveTrace in the bootstrap.properties file.
  3. Clear the "Disable logging and tracing of potentially sensitive data" checkbox.
  4. Add the entry com.ibm.websphere.logging.RawTraceList=off to the end of the trace string.

Question 14

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?

  1. Configure the JAVA_DUMP_OPTS environment variable to capture javacore for ANYSIGNAL and all exceptions.
  2. Configure an –Xdump:java Generic JVM argument on WebSphere Application Server with the filter for java.net.SocketTimeoutException.
  3. Code wsadmin script to capture javacore and then execute it after the java.net.SocketTimeoutException has been encountered.
  4. Use the log filter in HPEL to monitor for java.net.SocketTimeoutException and then gather a javacore dump from the Integrated Solutions Console (ISC).
