# ADAREP Utility

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.

## Delta Save Report Format

The following is an example of the Delta Save section in an ADAREP database report:

      ***********************

      * DELTA SAVE FACILITY *                           yyyy-mm-dd  hh:mm:ss

      ***********************

      DELTA SAVE STATUS = ENABLED

      DLOG AREA USAGE   = 2%

      LAST FULL SAVE NUMBER        = 2

      DATE/TIME OF LAST FULL SAVE  = 1997-01-19 04:03:36

      LAST DELTA SAVE NUMBER       = 5

      DATE/TIME OF LAST DELTA SAVE = 1997-01-24 22:39:45

      ESTIMATED NUMBER OF CHANGED BLOCKS = CA. 1,700 BLOCKS

      D S F   L O G G I N G   A R E A

      LIST I DEV  BLOCK I  SPACE ALLOC.  I  FROM     TO   I  UNUSED SPACE  I

## Delta Save Checkpoints

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

## JCL Requirements and Examples

This section describes the job control information required to run the ADAREP utility on z/OS, and shows an example job stream.

This section covers the following topics:

Data Set | DD Name | Storage | More Information
--- | --- | --- | ---
Associator | DDASSORn | disk |
Data Storage | DDDATARn | disk |
ADAREP parameters | DDKARTE |  |
ADARUN parameters | DDCARD |  | Adabas Operations
ADAREP messages | DDDRUCK |  | Adabas Messages and Codes
ADARUN messages | DDPRINT |  | Adabas Messages and Codes

#### Example

    //REP       EXEC PGM=ADARUN
    //STEPLIB   DD   DISP=SHR,DSN=ADABAS.Vvrs.LOADLIB
    //*
    //DDASSOR1  DD   DISP=SHR,DSN=EXAMPLE.ADA99.ASSOR1
