If a Delta Save logging (DLOG) area is defined in the database, the database report utility ADAREP additionally reports the Delta Save status. After the section about alternate RABNs, a Delta Save section is displayed with the following information:
Delta Save status (disabled or enabled);
percentage of the DLOG area used;
number of full save operations since installation of the DLOG area;
date and time of the last full save;
number of Delta Save operations since the last full save;
date and time of the last delta save;
estimate of the number of database blocks that would be saved in a current Delta Save operation. The estimate may be higher or lower than the actual number of blocks.
location, device type, block size, and number of unused blocks of the DLOG area.
If no DLOG area is defined, the Delta Save section is omitted.
This document covers the following topics:
The following is an example of the Delta Save section in an ADAREP database report:
***********************

DELTA SAVE STATUS = ENABLED

LAST FULL SAVE NUMBER = 2

The following additional checkpoints can be written by the Adabas nucleus or utilities and included in the ADAREP output when running with the Delta Save Facility:
| Checkpoint | Originated | Description | |
|---|---|---|---|
| Type | Name | By | |
| 0B | SYNP | ADASAV | End of SAVE DELTA operation |
| 0C | SYNP | ADASAV | End of RESTORE DELTA operation |
| 0D | SYNP | ADASAV | End of MERGE operation |
| 0E | SYNV | ADASAV | VOLSER entry for SAVE DELTA operation |
| 0F | SYNV | ADASAV | VOLSER entry for MERGE operation (output volumes) |
| 6A | SYNS | SYSAOS | DSF logging (DLOG) area installed |
| 6B | SYNS | SYSAOS | DLOG area changed |
| 6C | SYNS | SYSAOS | DLOG area removed |
