I have written and spoken often about the huge importance of instrumentation in an application. PeopleSoft introduced internal instrumentation to PeopleTools 8.44 for its own Performance Monitor that works on any platform. Since PeopleTools 7.53, when running on an Oracle database, PeopleTools also calls the Oracle supplied package dbms_application_info package to set the module and action for the session. The values set were not particularly useful, so I wrote a PL/SQL package (psftapi) and trigger to set the module and action attributes when a process started.

In PeopleTools 8.50 this instrumentation was enhanced to set module and action to the component and page name in the PIA. These values appear in Oracle Enterprise Manager and Active Session History (ASH). They can be used to profile components.

Now, in PeopleTools 8.52 Application Engine has been enhanced to set the action to the full Application Engine step name.

To illustrate what happens, I have produced an Oracle Extended SQL Trace for the process, but I have shown only the lines in a SQL Trace file with 3 asterisks. So you can see MODULE and ACTION being set (and some other timestamp information). The lines in italic were emitted when module and action were set by my psftapi package, in which I simply set the MODULE to the Application Engine program name.
