During startup, all relevant journal sequences are stored in the user index object with the name "<data group short name>_FLASH" in the MIMIX installation library.
This includes the IPL point, any Commit-IDs found, the Jump point MIMIX decided to jump back to when starting (usually the oldest of any Commit-ID), and their respective timestamps and job information.
You can view this information using the command:
DMPOBJ OBJ(<shn>_FLASH) OBJTYPE(*USRIDX)If you delete the user index and call the STRDGFLSH command again, it will think this is a first start of the data group, and re-search the journal for these journal sequences. However, you may want to first stop the data group if you want it to be restarted.
