Universal Messaging logs the activity of its client and its interaction with the Universal Messaging server. In particular, Universal Messaging logs responses from its server that deviate from what the client is expecting to happen. Typically these responses are in the form of exceptions. For example, if the client is not authorized to connect to the server, the server returns a security exception, and Universal Messaging logs that exception. Integration Server offers the ability to configure this logging in Integration Server Administrator instead of in Universal Messaging.

The Universal Messaging client log file is called umClient.log and is located in the following directory: Integration Server_directory /instances/instanceName/logs

You can also configure event lifecycle logging for Integration Server. Event lifecycle logging, also called trace logging, creates detailed log files describing the flow of a message (event) from the publishing Universal Messaging client through the Universal Messaging server to the subscribing Universal Messaging client. This is separate from the Universal Messaging client log. For more information, see Event Lifecycle Logging.
