Seems you are asking about Journalling concept..

Journalling is basically the recording activity of database files (PF) which records all the changes done to the PF like Add, update, delete, Open file and close file etc.

Following are the commands used for Journalling:

1. CRTJRNRCV - Create Journal Receiver
2. CRTJRN - Create Journal
3. STRJRNPF - Start Journal on Database file
4. ENDJRNPF - End Journal
