During the course of installation or uninstallation, log records are generated for the operations that occur. These records are saved into a single file in a format called Unified Logging Format (ULF). The Java ES installer Log Viewer utility (viewlog) provides a user-friendly interface for examining these log records. After Java ES installation is complete, the Log Viewer is located here:
Solaris OS: /var/sadm/prod/SUNWentsys5i
Linux and HP-UX: /var/sadm/prod/sun-entsys5i
After uninstallation, the viewlog utility is removed. The ULF logs themselves are not removed, and are located here:
Solaris OS: /var/sadm/install/logs
Linux and HP-UX: /var/opt/sun/install/logs
For instructions on using the Java ES logs and Log Viewer, refer to Examining Installation Log Files.
