Message Queue supports audit logging in Enterprise Edition only. When audit logging is
enabled, Message Queue generates a record for the following types of events:
Startup, shutdown, restart, and removal of a broker instance
User authentication and authorization
Reset of a persistent store
Creation, purge, and destruction of a physical destination
Administrative destruction of a durable subscriber
To log audit records to the Message Queue broker log file, set the imq.audit.enabled broker property to true . All audit records in the log contain the keyword AUDIT.
