Oracle Trace File Analyzer Collector performs three types of on-demand collections. Use the tfactl diagcollect command to perform all on-demand collections.

• Default Collections

  Default collections gather all important files and diagnostics from all nodes for all components where the file has been updated within a particular time frame. Oracle Trace File Analyzer trims, if it deems the files to be excessive.

  The standard time period used for the default collections is the past 12 hours. However, you can adjust to any other time period.

• Event Driven SRDC Collections

  Event driven Service Request Data Collections (SRDC) gather all important files and diagnostics related to a particular event, such as an error.

  The files and diagnostics collected depend on the event the SRDC collection is for. Oracle Trace File Analyzer prompts you for any other important information that it needs. Providing information enables Oracle Trace File Analyzer to understand how best to collect diagnostics about each event.

• Custom Collections

  Custom collections allow you to provide granular control over exactly what, how, and from where collected.
