Options allow you to view database-level general information and tables of database files, files whose extents are at or near the allowable maximum, file-specific information for any file, physical database distribution by volume/serial number (VOLSER), and available space that is not currently being used. Additional displays are available using direct commands.
The provided in AOS includes the following information, selected using the appropriate option code, as follows:
| Option | Function |
|---|---|
| C | Displaying Files with Critical Number of Extents shows a list of the files that have a critical number of extents. |
| D | Displaying Field Definition Table (FDT) shows the field definition table (FDT) and special descriptor table (SDT) for the specified file. |
| F | Displaying Files shows file(s), either a list of all files in the specified database or detailed information about a specific file. |
| G | Displaying General Database Layout shows the general layout of the specified database. |
| L | Displaying Volume/Serial Numbers for Database shows the volume/serial number layout of the specified database. |
| R | Displaying RABNs shows Associator / Data Storage blocks (RABNs). |
| U | Displaying Unused Storage shows unused storage. |
Option (List files with crit. no. of extents) on the menu provides a list of the files in the database that are at the critical number of extents. If no such files exist in the database, a message is displayed.
Note:
The exact extent count is provided in the general
Display File(s)
() option by table type (AC, NI, UI, or
DS).
Option (Display field description table (FDT)) on the menu provides a list of the field definitions in the FDT. The Display FDT screen appears.
Note:
For more detailed information about field definitions, read your
Adabas ADACMP utility documentation; for more information about interpreting
FDTs, read your Adabas ADAREP utility documentation. Both are available in the
Adabas Utilities documentation.

The PF2 (Reposition) key displays a window in which you can enter a new starting value for the file list. When you enter a file number, the Display Files list begins with that file.
If the extents (NI, UI, AC, and DA) listed on this screen exceed 99 and you want to see their actual values or if you would like to see the value of any secondary AC extent, press the PF4 (Extents) key. The window changes slightly to show the expanded values of the extents, although, due to screen space, the indicators are removed.
The Display Files screen provides the following information for each file:
file number and file name;
date the file was loaded into the database;
highest ISN currently in use in the file and the highest ISN allowed in the file;
number of logical extents currently assigned: by Associator ( N ormal index; U pper index; A ddress converter) and D ata Storage. A maximum of five logical extents may be allocated to a file.
block padding factor percentage defined for the Associator and for Data Storage;
indicators as follows:
| Indicator | Description |
|---|---|
| A | ADAM option: A = ADAM ISN- or descriptor-selected file; N = non-ADAM file. |
| C | coupled (C) or non-coupled (N) file. |
| I | ISNs are reusable (I) or not (N). |
| S | Data Storage blocks are reusable (S) or not (N). |
| E | data files are ciphered/encrypted (E) or not (N). |
| X | files are expanded (X) or normal (N). |
| U | USERISN option: U = option is in effect for the file; N = option is not in effect. |
percentage of allocated space currently used by the file in the Associator and in Data Storage.

Option displays two-doubleword-per-screen rows of the specified RABN block from the Associator or Data Storage in hexadecimal format. Both the hexadecimal data and its alphanumeric equivalent are displayed. If the block is not assigned, zeros are displayed.
The blocks are displayed in the length of the Associator or Data Storage block length.
You can scroll through the RABN display using the PF7 (scroll backward) and PF8 (scroll forward) keys. When using DISPLAY RABN, the offset switches to FFxx when you page past end-of-block. The display just continues to show the next block, until the offset reaches FFFF, when it returns to the first page.
You can display information for the next highest RABN (that is, the current RABN number plus one) by pressing PF4.
Option (Display unused storage) on the menu displays a table of unused storage within the database. The Display Unused Storage screen appears.
The equivalent direct command is
