— Adabas Utility Functions for Delta Save —

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.

This document covers the following topics:

JCL/JCS Requirements and Examples

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

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	Description
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/JCS Requirements and Examples

This section describes the job control information required to run the ADAREP utility with BS2000, OS/390, z/OS, z/VM, and VSE/ESA systems, and shows examples of each of the job streams.

This section covers the following topics:
