Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IMS Sequential Randomizer       *
  *                 Generator for OS/390 Release 1               *
  *                 (FMID=H1J1110) who are using DEDB            *
  *                 randomizers of SRTYPE=MULTI.                 *
  ****************************************************************
  * PROBLEM DESCRIPTION: If a DEDB randomizer of SRTYPE=MULTI    *
  *                      and CALLTYPE=XCI is used, ABEND0C4 or   *
  *                      another system abend can occur in IMS   *
  *                      control region.                         *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  The following problems can occur in a SRG DEDB randomizer of
  SRTYPE=MULTI:
  (1) ABEND0C4 or another system abend can occur in a DEDB
      randomizer of SRTYPE=MULTI and CALLTYPE=XCI at the
      initialization of IMS control region or when a
      /DBRECOVERY DB or a /START DB command is issued against
      the DEDB for which the randomizer is used.
  (2) In the DEDB randomizer of SRTYPE=MULTI and CALLTYPE=STD,
      the label name specified on the EPLOC parameter of IMODULE
      macro that is issued when the overflow table is deleted is
      not correct.
  

Problem conclusion

• The line of sequence number 02280000 in XCIPROLG routine in
  FABOFXCI has been modified to do branching to the label
  FXCIEXIT, not to return to the caller. This modification
  resolves the problem (1). The macro FABOF has been modified to
  specify the correct name in EPLOC parameter of the IMODULE
  macro, although the overflow table is successfully deleted by
  the current logic explained in the problem (2).
