Q38: What logs are available and how will they help me?

Answer: Information on all installation events is captured in the installation logs described in Examining Installation Log Files in Sun Java Enterprise System 5 Installation Guide for UNIX. Always start any troubleshooting by scanning the log events to see what errors occurred. The logs usually give you an idea of what to do next. Two types of tracking files are available after Java ES installation:

• Installation summary The installation summary lists each component installed and the settings you specified. If you chose Configure Now, this summary includes all of the configuration values except passwords.

• Installation log Installation logs display the installer log messages. The JavaES_Install_log.timestamp is one of the most critical logs to examine in the event of a configuration issue. This log contains the output of the configuration tools for each product component that was installed in a Configure Now installation.

The graphical Log Viewer is a utility that can be used to view Unified Logging Format (ULF) messages from the Java ES installation log. See Using the Log Viewer in Sun Java Enterprise System 5 Installation Guide for UNIX.

Links to the installation logs and summary are on the last page of the installer. Log files are located here:

• Solaris OS: /var/sadm/install/logs

• Linux and HP-UX: /var/opt/sun/install/logs

If a problem occurs when starting a particular component, examine the troubleshooting tips tables to find the location of log files for the individual Java ES components. See Product Component Troubleshooting Tips in Sun Java Enterprise System 5 Installation Guide for UNIX.
