Restrictions for the DBD/PSB/ACB Mapper utility

Certain restrictions apply when you use the DBD/PSB/ACB Mapper utility.

DBD/PSB/ACB Mapper can produce a map and a report for the DBD of any IMS™ database organization, except GSAM. Because GSAM has no segment, only a report can be prepared.

If the reports of IMS Library Integrity Utilities are printed on a 3800 printer, text fonts GT15 and ST15 used at 12 lines per inch (LPI) do not work. The reason is that the underscore (_) character, which is used to draw the horizontal lines for the DBD hierarchy, are not printed. Fonts GSC and GFC can be used. The GT15 and ST15 fonts can be used at 6 and 8 LPI.

When the parameter values added by certain versions and releases of IMS are the default values, the fields for those parameters are not printed in the report for DBD or PSB.
