DBD Map panel


If you have selected a DBD or a DBD-type ACB for mapping, Database Integrity displays the DBD Map report.

This report shows a standard hierarchical diagram of the structure of the selected control block. The following figure shows an example of this panel.

Description

DBDNAME

The name of the DBD or DBD-type ACB.

xxxLIB

The data set name of the library containing the control block. xxx is the type of control block: DBD or ACB.

+nn-------d+
+ segname  +

+..........+
+ segname  +
+.......VIR+

The report contains a box for each segment defined in the DBD. The segment code (nn) appears in the top left border of the box. The data set group number (d) appears in the top right border. If the input control block is a DBD, the center of the box contains the segment name. If it is an ACB, the segment name is not available and the characters **SCnn** are substituted for the segment name. Vertical and horizontal lines extended from the segment to show the relationship between the segment and its parent, children, and/or twins.

The border of the box indicates whether the segment is real or virtual. Dashes (-) indicate a real segment. A border of dots (.) and the literal VIR in the bottom right corner indicate a virtual segment.

segtype=segname, DB=database

The report shows secondary index and logical relationship segments without a box. It notes the type of segment and its name with the segtype=segname field. The following values are possible for segtype:

PX

Primary index segment

SX

Secondary index segment

LC

Logical child segment

LP

Logical parent segment

The report provides the name of the database that contains the primary index, secondary index, logical child, or logical parent segment with the DB field.
