Viewing the service log

Service logs are logs written in a binary format. We cannot view a service log directly using a text editor. You should never directly edit the service log, as doing so will corrupt the log.

 

Before you begin

To move a service log from one machine to another, use a mechanism like FTP, which supports binary file transfer. We can view a service log in two ways:

• It is recommended that you use the Log Analyzer tool to view the service log. This tool provides interactive viewing and analysis capability that is helpful in identifying problems.

• If you are unable to use the Log Analyzer tool, use the Showlog tool to convert the contents of the service log to a text format that you can then write to a file or dump to the command shell window.

 

About this task

Run the showlog script to view the contents of the service log as described in the following procedure.

 

Procedure

1. Open a shell window on the machine where the service log resides.

2. Change the directory to app_server_root/bin where app_server_root is the fully qualified path where the WAS product is installed.

3. Run the showlog script.

   showlog.bat

   showlog.sh

4. Run the following showlog script with no parameters to display usage instructions.

   showlog.bat

   showlog.sh

5. Display the service log contents to the shell window.

    showlog service_log_filename
   

   If the service log is not in the default location, fully qualify the service_log_filename

6. Format and write the service log contents to a file.

    showlog service_log_filename output_filename
   

   If the service log is not in the default location, fully qualify the service_log_filename
