A number of product components have installation-time interdependencies. Problems that affect one product component can affect other product components. First, you should familiarize yourself with the information in Sun Java Enterprise System 5 Installation Planning Guide.
Review the summary file and log files to see whether related products have failed. These might provide a clue as to what to fix first.
Check that you have specified correct connection information. For example:
Does the information that you provided when configuring Directory Server match the directory information you provided for product components that use Directory Server?
Does the Access Manager information that you provided for Portal Server or Portal Server SRA match the information you provided for Access Manager? See the Sun Java Enterprise System 5 Installation Guide for UNIX for information on Portal Server installation.
In addition to product component interdependencies, some product components depend on the existence of Solaris packages that might not be installed on the host, and their absence could cause installation failures. Read the “Software Requirements” section of the Release Notes for details.
If a problem occurs starting a product component, examine that product component's log files. Locations of many product component log files are listed in Product Component Troubleshooting Tips.
