Local error logs

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.

Windows platformOn Windows, the local error log is the Windows Event log (Application view).

UNIX platformOn 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.

z/OS platformOn z/OS®, the local error log is the operator console.

Entries in the local error log that are generated by IBM Integration Bus are identified in the following way:
  • Windows platformOn Windows: by events from the source IBM Integration v**** and a message number in the form nnnn, where **** is the current four-digit product version number.
  • UNIX platformOn UNIX: by a message number in the form BIPnnnn.
  • z/OS platformOn z/OS: by a started task ID, and a message number in the form BIPnnnn.

For the syslog on UNIX and Linux systems, and the z/OS operator console, setting the deprecated environment variable MQSI_SYSLOG_COMPATIBILITY_FORMAT to any value has the effect of reverting the formatting of messages to that used in WebSphere® Message Broker Version 8.0 and earlier versions.

When an integration node 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).

Windows platformOn Windows, the event log can fill up; ensure that you have a log size that is sufficient, or that you have enabled circular logging.
