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?

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.
What should the administrator do to continuously monitor logs for the required message?

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 correlationld 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?

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 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 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?

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?

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:
• Monitor how much time is spent in the various parts of the environment.
• Determine the concurrent usage of the site.
• Identify potential memory leaks.
Which PMI modules can the administrator examine to obtain this data?

A system administrator decides to use the advice from the Performance and Diagnostic Advisor to
identify the optimum connection pool settings for data sources. In a cell, the data source
db2datasource is defined under node scope and used by two servers from that node. The
administrator receives two different sets of advice for db2datasource.
. One set of advice suggests to increase the maximum connection pool size for
db2datasource.
. The other suggests reducing the maximum connection pool size for db2datasource.
How should the administrator configure the data sources before reusing the Performance and
Diagnostic Advisor?

A system administrator in a bank was asked by business users to determine the most accessed
