Enterprise Server instances and the Domain Administration Server produce annotated logs on the file system. By default, all errors, warnings or useful informative messages are logged.
From the Common Tasks list in the right pane, click Search Log Files to launch a new browser window for Log Viewer.
In the Log Viewer window, select “server” from the Instance Name drop-down list and click Search.
The Domain Administration Server’s recent log file entries are displayed.
Scan the messages and look for any WARNING or SEVERE messages indicating that problems were encountered during server startup.
You can close Log Viewer at any time. After you create clusters and deploy applications, examine log files if any of the operations failed. Use Log Viewer to view the log files of any running Enterprise Server instance in the domain.
