IWMMSTRT – Indicating the Start of a Work Unit

This service indicates that a work unit is beginning execution. The work unit runs under the specified monitoring environment, but is reported to EWLM completely independently from a potentially running transaction on the same monitoring environment that is defined by IWM4MINI and IWMRPT/IWMMNTFY calls. You can use the set of services IWMMSTRT, IWMMSTOP, IWMMUPD to provide data for "mini work units" running within a long-running transaction. In addition, a work unit started by IWMMSTRT can participate in asynchronous and synchronous work unit flows.
