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?

1. A. Run the installver command with the appropriate command line options.
2. B. Check the files under the Agent data location of IBM Installation Manager.
3. C. Check the files under the logs directory of IBM Installation Manager installation directory.
4. D. Check the log.txt under <WebSphere Application Server install directory><logdirectory>.

Correct Answer: C
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

A newly deployed application has authorization errors when invoking EJB methods from a servlet. An additional review indicates that users are authenticated, but do not have the correct authorization.

A system administrator needs to create a cell for a test environment. The administrator uses the Profile Management Tool (PMT) to create the deployment manager profile using the advanced profile creation option and creates a custom profile using the typical profile creation option. The administrator examines the log files for the custom profile creation and sees an INSTCONFFAIL message indicating the deployment manager was not running during the custom profile creation.
How should the administrator fix this?

1. A. Delete the custom profile.Start the deployment manager.Create the custom profile again.
2. B. Start the deployment manager.Use PMT to re-create the custom profile.
3. C. Use the syncNode command to synchronize the node.
4. D. Run the addNode command to federate the custom profile.

Correct Answer: A
Deleting profiles. You can delete a profile using the manageprofiles command. If the command fails, you can delete the profile using operating system commands.
Before you begin: If a node within a profile is federated to a deployment manager, before you delete the profile, stop the node and remove the node from the deployment manager.
Otherwise, an orphan node remains in the deployment manager.
