Oracle iPlanet Web Server 7.0.9 Troubleshooting Guide

Seeking a Solution

After identifying the problem, you are ready to do some investigation.

The following topics are addressed in this section:

Verify System Configuration

Sometimes the most obvious solutions are overlooked, and so the first step is to verify the system configuration. Refer to the Oracle iPlanet Web Server 7.0.9 Release Notes for the most up-to-date system requirements and dependencies.

Evaluate Messages

Messages generally include information about the attempted action, the outcome of the action, and, if applicable, the cause of jeopardy or failure.

Types of Messages

The log files contain the following general types of message entries:

Error Messages

A problem is often accompanied by an error message that prevents the application from proceeding.

Examine Log Files

A number of the Web Server subsystems create log files and log their events to these files. The primary purpose of these log files is to provide troubleshooting information.


Note –

Web Server Error Logs are the first place you should look for information, when you need to troubleshoot a runtime issue. For issues related to installation, see the installation log files.


In addition to the message text, a logged message provides the following information:

Log Levels

The Web Server has many log levels that can be set in the Admin Console (FINEST, FINER, FINE, CONFIG, INFO, WARNING, SEVERE, ALERT, and FATAL). All messages are logged when the log level is set to FINEST and only serious error messages appear if the log level is set to FATAL.

Note that the more detailed log levels (FINEST, FINER, FINE) can generate high volumes of log information for certain events, which may make it appear at first glance that there is an error condition when in fact there is not.

All messages with a log level less than the default level of INFO (FINEST, FINER, FINE, and CONFIG) provide information related to debugging and must be specifically enabled. Instructions for doing this are contained in the Oracle iPlanet Web Server Administrator's Guide.

In addition to the standard JDK log levels, the Web Server has added log levels designed to map more intuitively to the Web Server log file (server.log) and to tightly integrate with Solaris. The log levels ALERT and FATAL are specific to the Web Server and are not implemented in the JDK1.4 logging API.


Note –

For information on the event log mechanism used in the Microsoft Windows operating environment, refer to the Windows help system index using the keywords Event Logging. If you choose to send logs to the Windows server.log file, only messages with a log level of INFO, WARNING, SEVERE, ALERT, or FATAL are logged to the Windows Event Log.


Log Options

The Admin Console provides the following two logging options:
