Description

A <milestone> activity writes a message to the Ensemble database. <milestone> works very much like <trace>, but unlike <trace> messages, <milestone> messages exist only while the associated business process is running. After the business process exits, all messages generated by <milestone> activities are removed.

Often a programmer uses <trace> messages for diagnostic purposes, whereas <milestone> messages can be helpful to track the progress of a correctly operating, long-running business process.

You can retrieve <milestone> messages by examining values in the Ens.Milestone global. The global is defined only if your production has issued <milestone> messages. To obtain the value of Ens.Milestone:

  • Programmatically, use the information in the “Using Multidimensional Storage (Globals)” chapter in Using Caché Multidimensional Storage.

  • From the Management Portal, navigate to the System,Globals page, ensure that the Namespaces option is selected, and click on the name of the Ensemble namespace where your production runs. The View Globals option is selected by default.
