IBM® Integration Bus 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.
When a broker encounters an error, more than one message can be written to the local error log. Typically these messages 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).
On Windows, the event log can fill up; ensure that you have a log size that is sufficient, or that you have enabled circular logging.
