This document describes the utility "ADAREP".
The following topics are covered:
The ADAREP utility generates the database status report. This contains information about the current physical layout and logical contents of the database. Unless otherwise stated, the functions can be executed when the nucleus is active or inactive.
The information contained in this report includes:
The amount and location of space currently allocated for the Associator and Data Storage;
The amount and location of unused space available for the Associator and Data Storage;
Database file summary;
Checkpoint information;
Information about each file in the database (space allocation, space available, number of records loaded, MAXISN setting, field definitions, etc.);
Only the CHECKPOINTS control parameter (see description below) requires the nucleus to be active.
This utility is a multi-function utility.

The utility writes no checkpoints.
The following control parameters are available:
CHECKPOINTS = { * | ( [absolute-date] [,[absolute-date] ] ) } CONSTRAINTS CONTENTS M DBID = number D [NO]FDT FILES = { * | (number [-number][,number[-number]]...) } D [NO]FULL FREE_SPACE LAYOUT SUMMARY
CHECKPOINTS = { * | ( [absolute-date] [,[absolute-date]] ) }
This function displays selected information from the checkpoint list and requires the nucleus to be active.
Five types of system checkpoints (SYNP, SYNC, SYNX, OPEN and CLSE) are written to the checkpoint file and to the protection log, together with the user checkpoints written by C1 commands.
SYNC indicates a checkpoint made during nucleus initialization, shutdown or cancel processing; during the ADAOPR function FEOF = PLOG; or due to ADABCK NEW_PLOG processing.
SYNP indicates a checkpoint made by an Adabas utility that requires privileged control, i.e. the module can make updates without using the nucleus. A SYNP checkpoint is, for example, written at the end of an ADAMUP UPDATE run.
SYNX indicates a checkpoint made by a utility that requires exclusive control of one or more files. A SYNX checkpoint is, for example, written by ADAULD.
An OPEN checkpoint is written by the OP command of EXU/EXF users.
A CLSE checkpoint is written by the CL command of EXU/EXF users.
Note:
If the ADAREC `REGENERATE' function is executed using the Protection
Log, this utility stops at each SYNP checkpoint since DBA intervention is
required.
If an asterisk `*' is entered, all checkpoints are displayed.
The date strings must correspond to the following absolute data and time format:
dd-mmm-yyyy[:hh[:mm[:ss]]]
Leading zeroes in the date and time specification may be omitted. Any numbers not specified are set to 0, for example 28-jul-2006 is equivalent to 28-jul-2006:00:00:00.
The following table shows the possible values for parameter CHECKPOINTS, and the corresponding checkpoints displayed by this value:
| Value specified for parameter CHECKPOINTS | Checkpoints displayed for this specification |
|---|---|
| * or (,) | All checkpoints |
| absolute-date | Only the checkpoints written exactly at the date and time specified |
| (absolute-date,) | Checkpoints written from date and time specified onwards |
| (,absolute-date) | Checkpoints written up to the date and time specified |
| (absolute-date,absolute-date) | Checkpoints written from first date and time value specified onwards up to the second date and time value specified |

All checkpoints are displayed.
The column "User ID / Function" contains
for user checkpoints created via OP/CL commands for EXU/EXF users or via C1 command: the user specified in the Additions 1 field of the relevant OP command;
for utility checkpoints: the utility function executed.
Taking the output of the example above (checkpoints=*), the selection criteria can be used to filter the checkpoints selected as shown below.

The column `Extents' shows the number of logical extents currently assigned to the Normal Index (N), the Main/Upper Indices (U), the Address Converter (A) and Data Storage (D).
The column `Pad' shows the block padding factors in percent defined for the Associator (A) and Data Storage (D) (please refer to the ASSOPFAC and DATAPFAC parameters of ADAFDU, ADAMUP or ADAORD for more detailed information).
The column `Flags' contains the following information:
| Subcolumn | Flag | Meaning |
|---|---|---|
| A | A | Indicates an Adam file |
| L | L | File is a LOB file |
| B | File is a base file with a corresponding LOB file | |
| R | R | ISN and space reusage enabled for the file |
| I | ISN reusage, but no space reusage enabled for the file | |
| S | Space reusage, but no ISN reusage enabled for the file | |
| C | C | Ciphering enabled for the file |
| P | P | Program Refresh enabled for the file |
If ISNs are to be reused, the ISNs of deleted records can be reassigned to new records. If space is to be reused, the space released within a block as a result of deleting a record can be reused for a new record (please refer to the REUSE parameter of ADADBM or ADAFDU for more detailed information).
The second table shows the number of blocks allocated for Normal Index (NI) Main/Upper Indices (UI), Address Converter (AC) and Data Storage (DS) for each file. The remaining columns show the number of unused blocks in the Main/Upper Indices (UI) and Data Storage (DS).
DBID = number

The FILES parameter displays the file number and file name, the highest index level, the padding factors for ASSO and DATA, the highest and maximum ISNs, the number of records loaded, the corresponding base file number or LOB file number if it exists, as well as the switches for ISN reusage, space reusage, program refresh and ciphering. The time and date of the last FDT modification are also displayed.
The layout of the ASSO and DATA elements of a file are displayed: the block size on which the various list elements are stored, the location of these extents and the number of corresponding blocks/megabytes allocated or unused.
In addition, the FDT function displays the Field Definition Table of the file.
The flags which can be displayed in the Field Definition Table are as follows:
| Flag | Meaning |
|---|---|
| HY | the field is part of a hyperdescriptor |
| P | the field is phoneticized |
| SB | part of this field is subdescriptor |
| SP | part of superdescriptor |
FREE_SPACE
This function displays a summary of free blocks in ASSO and DATA. This is a subset of the information that is displayed by the LAYOUT function.

If FULL is specified together with FDT, dropped fields will be included in the display of the FDT information (but without the field names).
The default is NOFULL.
LAYOUT
This function displays a summary of the blocks in ASSO and DATA and reports lost blocks. Lost blocks are blocks that are not listed in the Free Space Table (FST) and are not allocated to a file, the DSST or the database's global area. This function also reports double-allocated blocks.

LAYOUT provides a summary of all blocks in ASSO and DATA. The locations and lengths of sections of contiguous blocks, the block size, the type of usage and the numbers of the corresponding files are displayed. These blocks may be free (FREE) or used for the Global Blocks (CB), the File Control Block (FCB), the FCB extension (FCBE), the FCB Root Block (FCBR), the Field Definition Table (FDT), the Free Space Table (FST), the Data Space Storage Table (DSST), the Normal Index (NI), the Upper/Main Index (UI), the Address Converter (AC) or the Data Storage (DS).
Note:
The first FCBR block and the first FST block are part of the global
blocks. For this reason, the layout only displays FCBR and FST blocks if the
database contains more than one of these blocks.
