Tip: When installing CIM make sure that the Windows firewall allows
connections from the CIM
The repository for the CIM can either be created during the installation of
WebSphere Application Server Network Deployment V7.0 or afterwards using
the Installation Factory. The installation using the CIM provides a good approach
to perform centralized remote installations and upgrades. The drawback is that
you cannot control the naming of the profiles created when performing standard
installation. This problem can be avoided by using custom installation packages
created through the installation manager.
For more details about CIM, refer to the IBM White Paper Centralized Installation
Manager for IBM WebSphere Application Server Network Deployment Version
7.0, available on the following Web page:

A major challenge of problem management is dealing with unanticipated
problems. It is much like detective work: find clues, make educated guesses,
verify suspicions, and so on. The most important skills are common sense, focus,
thoroughness, and rigorous thinking. A proactive approach to problem
management is always the best. This section outlines general practices to follow.
Perform the following checks to avoid issues with the runtime environment:
► Check that you have the necessary prerequisite software up and running.
► Check that the proper authorizations are in place.
► Check for messages that signal potential problems. Look for warnings and
error messages in the following sources:
– Logs from other subsystems and products, such as TCP/IP, RACF,
Windows Event Viewer, and so forth.
– WebSphere Application Server SystemOut and SystemErr logs.
– SYSPRINT of the WebSphere Application Server for z/OS.
– Component trace output for the server.
