DBD Summary report using the DBDINFO command
When you use the DBDINFO command (F9 in the NEWPFK set on the Segment and Block panels), the Database Zap utility displays the DBD Summary report in place of the pointer and data information or block information on the panel.
Use the RESET command (F5) to redisplay the pointer and data information or block information. The header information and function key definitions do not change.

The Database Zap utility obtains the values for the following fields from information in the DBD control block.
DATABASE | The DBD name of the database. |
|---|---|
DS GROUPS | The number of data set groups in this DBD. |
ORGANIZATION | The database organization of this database (HDAM, HIDAM, etc.). |
ACCESS METHOD | The access method for this database (OSAM or ESDS). |
RANDOMIZER | The name of the HDAM randomizing routine as specified in the DBD (for HDAM databases only). |
NUMBER RAPS | The number of root anchor points per block or CI as specified in the DBD (for HDAM databases only). |
MAX RBN | The maximum relative block number for this database as specified in the DBD (for HDAM databases only). |
MAX INSERT | The maximum number of bytes that may be inserted into the root addressable area with one series of calls to a database record as specified in the DBD (for HDAM databases only). |
PRIMARY INDEX DBD | The DBD name for the primary index (for HIDAM databases only). |
PRIMARY INDEX ACCESS METHOD | The access method for the primary index (for HIDAM databases only). |
SEGMENT | The segment name. |
SEG CODE | The 1-byte hexadecimal code that identifies the segment in the database. |
LVL | The segment hierarchical level. |
DSG | The segment data set group. |
PARENT | The name of this segment’s parent. |
PFX LEN | The segment prefix length (in bytes). |
DATA LEN | The segment data length (maximum length if the segment is variable length). |
FLAG | A flag to indicate the status of the segment. The following values are possible:
|
PTR TYPE | The types of pointers contained in the segment’s prefix, listed in the same order as they appear in the segment prefix. |
TARGET SEGMENT | The name of the segment to which the segment prefix pointer is pointing. For hierarchical pointers, the target segment type may vary. |
TARGET DBDNAME | The name of the database that contains the target segment. A DBD name will be shown only if the target segment is in a different database from the source segment. |
