Version 12.0 Enhancements › New Trace Facility

New Trace Facility

This release offers a trace facility in the Base CAENF product with the following characteristics:

• The tracing facility uses the standard IBM Component Trace facility.
• ENFCT is an optional ENF parameter file statement. This statement lets you define:
  • The component name
  • The number of buffers
  • The size of a buffer
  • The Component Trace parmlib member name (to set the default tracing).
• The traced ENF events can be assigned a trace event ID.
• Event ID Groups (EIDG) are provided as a way to group sets of trace event IDs. EIDGs allow a single identifier to be used, rather than having to list each event ID individually.
• Trace sets that define a set of EIDGs to be traced are provided and are referenced with a trace Set ID.
• The Component Trace Start/Stop Routine (SS-Routine) provides the interface for activating, deactivating, defining, deleting, enabling, disabling, modifying, pausing, resuming, and listing status or information about trace sets.
• The SS-Routine lets you connect and disconnect the Writer. The routine also provides a default Component Trace parmlib member defining L1 and C1 as the default Event ID Groups to be traced.
• Tracing can be paused and resumed to allow or disallow tracing internally.

TRACE CT,ON processing can manipulate trace sets while the internal tracing is inactive. The Writer can remain connected while internally the tracing is paused.

• When tracing is deactivated, activated, paused, or resumed, unless other parameters apply, the status of the trace sets is not altered.
• Filtering at capture time is based on Event ID Groups, ASID, and JOBNAME.
