WebSphere Message Broker components use the local error log (also known as the system log) to record information about major activities within the system. When an error occurs, check the local error log first.
On Windows, the local error log is
the Windows Event log (Application view).
On UNIX and Linux systems,
the local error log is the syslog.
Where syslog messages are sent depends on how you configure your UNIX or Linux system.
On z/OS, the local error log is
the operator console.

Typically these start with a general message (for example, Could not process a message), and further messages give more details about the cause of the error (for example, An error was detected while processing the following SQL statement...).
