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?
Monitoring overall system health. To monitor overall system health, monitor the following statistics at a minimum:
A system administrator has created a Jython script that will run in WebSphere Network cell where administrative security is enabled. This script is named doUpdate.py and will be run by using the following:
wsadmin --connType RMI --f doUpdate.py
How can the administrator suppress a user/password prompt from appearing when this script is run?
Set the user and password in the:
The user Id and password needed for wsadmin to connect to a secured server can be supplied as command line options and in properties files. If used together, command line options take precedence over what is in the properties files. The properties files are located at Profile_root/properties.
If you use a Remote Method Invocation (RMI) connector or a JSR160RMI connector, set the following properties in the sas.client.props file with the appropriate values:
com.ibm.CORBA.loginUserid=
com.ibm.CORBA.loginPassword=
A system administrator needs to install WebSphere Application Server using response files, so that a silent install can be done. The administrator has ensured that all required prerequisites have already been installed and, has downloaded and expanded the required WebSphere Application Server installation files.
What can the administrator run to install the product?
Example of the use of the response files to install the product.
imcl.exe -acceptLicense
input C:\temp\keyring_response_file.xml
-log C:\temp\keyring_log.xml

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?
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
