Viewing the exception log

The exception log enables the diagnosis of exceptions that occur at any time during processing on an integration server.

About this task

The exception log is written to the following location:
MQSI-WORKPATH/common/log/IntegrationNodeName.IntegrationServerUUID.exceptionLog.txt
The exception log is a rolling collection of 4 files; when a file is full, data is added to the next file. When the last file has been filled, data starts to be added to the first file, overwriting the previous data there. This cycle of writing continues, ensuring that the newest data is retained. Restarting the integration server causes the previous log to be moved and a numeric suffix added to it.
The exception log includes:
  • A summary or short description of the exception
  • A list of the exception's inserts
  • Message numbers of any nested exceptions
  • Optionally, details recorded by the Flow Thread Reporter. If the exception occurs in a message flow, the Flow Thread Reporter provides data to enable you to identify the location in the message flow at which the exception occurred.
Exceptions are listed in the order of their creation.

Procedure

Access the exception log by navigating to the following location: MQSI-WORKPATH/common/log/IntegrationNodeName.IntegrationServerUUID.exceptionLog.txt
Example of an exception log entry:
2019-09-30 09:07:35.566215        14744     THROWN  BIP2677E  RecoverableException    MQConnection::open  'Failed to connect to queue manager' ['remoteQM', 
'localhost', 1234, 2, 2538]    DataFlowEngine/Connectors/mqconnector/MQConnection.cpp:404
Example of the same exception log entry including details recorded by the Flow Thread Reporter:
2019-09-30 09:09:39.367336        14743     THROWN  BIP2677E  RecoverableException    MQConnection::open  'Failed to connect to queue manager' ['remoteQM',
