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 completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs. The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run.
How can the administrator decrease the size and remove some of the content from the shared resources directory?
Because product payloads are cached in this directory, space requirements can grow very large over the lifetime of the product, as service updates are applied. The WebSphere Application Server product image is large, so if this content is permitted to accumulate, then this directory will grow to be many gigabytes in size over the course of multiple fix pack applications. You should never manually delete the content in this folder. Instead, during any installation or maintenance operation, you can specify the following preference to remove some of the content in this folder:
--preferences com.ibm.cic.common.core.preferences.preserveDownloadedArtifacts=false
A web application is hosted on an application server that receives HTTP requests from a third party application named myApp. The URIGroup mapping for this application is called default_host_myApp.
The development team asks a system administrator to configure the HTTP plug-in to prevent routing requests to any application server except server1.
The following exhibit shows the parts of the plugin-cfg.xml file that are relevant for myApp. The UriGroups for other applications are not shown in the exhibit.

What should the administrator do to the plugin-cfg.xml file to ensure that requests for default_host_myApp URIGroup are routed only to machine1?
The installation of WebSphere Application Server did not complete successfully, and a system administrator needs to troubleshoot the installation.
What can the administrator do to identify the cause of the installation failure?
Installation Manager creates log files that you can use to troubleshoot any installation problems. Consider verifying the log files after any installation to ensure that everything in that process went successfully.
To examine the logs manually, locate the Installation Manager logs directory. The default location for this directory varies according to the operating system:
Windows: C:\ProgramData\IBM\Installation Manager\logs
UNIX: /var/ibm/InstallationManager/logs
References:
A system administrator in a bank was asked by business users to determine the most accessed JSP page in a web application at normal work load for marketing purpose.
Which tool should the administrator use to find the most used JSP page?
Summary reports are available for each application server.
Tivoli Performance Viewer provides the following summary reports for each application server:
The servlet summary lists all servlets that are running in the current application server. Use the servlet summary view to quickly find the servlet that consumes the most time and the applications that use them, and to determine which servlets are invoked most often.
