Restrictions for the DBD/PSB/ACB Reversal utility
Certain restrictions apply when you use the DBD/PSB/ACB Reversal utility.
DBD/PSB/ACB Reversal re-creates the DBD/PSB source to be used for IMS™ of the same version and release
by which the DBD/PSB were generated or for higher version of IMS. If a DBD/ACB member for HALDB
is used as input data, the following reports are not generated, because
the DBD/ACB library contains no information about the DD name:
- DBD XREF by DDname report
- ACB(DBD) XREF by DDname report
If the DBD member is specified to generate the reports, message FABN0054I is issued.
DBD/PSB/ACB Reversal cannot create reports if an alias name that
is defined to the database is specified on the following control statements:
- XREF
- DDNAMES
- SEGREF
For the restrictions that apply to the generated control statements, see Restrictions on the generated control statements.
