Question #8
A system administrator runs a Python script that creates and configures several servers and realizes 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?

Question #9
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:
How can the administrator determine that the hung threads are a false alarm?
Analyze the:
- Affdc logs
- BSystemErr.log
- CSystemOut.log
- Dnative_stderr.log
Correct Answer:
C
Problem(Abstract)
The SystemOut.log contains a WSVR0605W message, also called a hung thread message. A javacore, or thread dump on Solaris and HP-UX, is needed in order to determine how to resolve the potentially hung threads.
Cause -
WebSphere Application Server attempts to report potentially hung threads using the hung thread detector. Depending on how the hung thread detector policy is configured, a thread running for a certain interval (default 10 minutes) might be reported as hung and a WSVR0605W message is printed in the SystemOut.log file:
WSVR0605W: Thread <threadname> has been active for <time> and may be hung. There are <totalthreads> in total in the server that may be hung.

Question #10
A system administrator suspects that the slow performance of an application might be caused by lock contention.
To debug this further, what can the administrator do using IBM Support Assistant?
To debug this further, what can the administrator do using IBM Support Assistant?
- AAnalyze the running server using IBM Monitoring and Diagnostic Tools for Java – Health Center.
- BCollect a javacore and analyze it using IBM Monitoring and Diagnostic Tools for Java – Health Center.
- CCollect three thread dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java – Dump Analyzer.
- DCollect three system dumps at equal time intervals and analyze them using IBM Monitoring and Diagnostic Tools for Java – Memory Analyzer.
Correct Answer:
A
The IBM Monitoring and Diagnostic Tools for Java - Health Center is a lightweight tool that monitors active IBM Virtual Machines for Java with minimal performance overhead. The Health Center suggests live tuning recommendations for Garbage Collection, profiles methods including call stacks, and highlights contended locks. This information can help you optimize performance, improve stability and optimize system resource usage.
The tool is provided in two parts:
✑ An agent, which collects data from a running application. Java applications are monitored by the Health Center agent
The Health Center client, an Eclipse-based GUI which connects to the agent. The client interprets the data that is obtained by the agent and provides
recommendations to improve the performance of the monitored application. The client is available as an Eclipse plug-in and as part of IBM Support Assistant
(ISA).
