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.
