WebSphere MQ accounting traces

WebSphere® MQ accounting records are produced as a result of activating the Accounting Trace component of WebSphere MQ. That activation is a consequence of either coding a suitable parameter in a WebSphere MQ control block or by the issuing of a WebSphere MQ subsystem command from the MVS™ Operator Console. If the WebSphere MQ accounting trace is active, WebSphere MQ SMF accounting records (type 116) are produced with a subtype (0, 1 or 2) depending on what level of trace has been activated. If the MQ accounting trace is active, subtype 0 records are always produced but subtypes 1 and 2 are only produced if CLASS(3) is specified when the trace is activated; this can only be performed via an MVS Operator Command.
