    *                      but FM/IMS does not delete all the      *
    *                      members from the DOPT ACBLIB data set   *

    *                      6. Problems with the BMP Mode Options   *
    *                      and the BMP Mode Parameters panels:     *
    *                      i. The panels always display the IMS    *
    *                      subsystem defaults for the options and  *
    *                      parameters. When the FM/IMS             *
    *                      installation options module specifies   *
    *                      that the user can override the default  *
    *                      for an option/parameter, the panel      *
    *                      should display the value that the user  *
    *                      previously specified for that           *
    *                      option/parameter.                       *
    *                      ii. The panel field for an              *
    *                      option/parameter is not protected when  *
    *                      the FM/IMS installation options module  *
    *                      specifies that the user cannot override *
    *                      the IMS subsystem default for the       *
    *                      option/parameter.                       *
    *                      iii. When you update the panel field    *
    *                      for an option/parameter and use the     *
    *                      EXIT command (F3) to exit the panel,    *
    *                      the value you specify is not saved in   *
    *                      the user profile.                       *
    *                                                              *
    *                      7. A CHKPFREQ= statement specified in   *
    *                      the FMIMSIN DD input of a Load (ILB) or *
    *                      Batch Edit (IEB) job is not ignored     *
    *                      when REGNTYPE=BMP is specified and the  *
    *                      FM/IMS installation options module      *
    *                      specifies that the user cannot override *
    *                      the IMS subsystem default for the Load  *
    *                      or Batch Edit checkpoint frequency.     *
    *                                                              *
    *                      8. A PROCOPT= statement specified in    *
    *                      the FMIMSIN DD input of an Extract      *
    *                      (IXB), Print (IPR) or Batch Browse      *
    *                      (IBB) job is not ignored when           *
    *                      REGNTYPE=BMP is specified and the       *
    *                      FM/IMS installation options module      *
    *                      specifies that the user cannot override *
    *                      the IMS subsystem default for the       *

    *                                                              *
    *                      9. A PARDLI=, IMSOBA=, IMSNBA= or       *
    *                      LOCKMAX= statement specified in the     *
    *                      FMIMSIN DD input of an Extract (IXB),   *

    *                      (IEB) or Batch Browse (IBB) job is not  *
    *                      ignored when REGNTYPE=BMP is specified  *
    *                      and the FM/IMS installation options     *
    *                      module specifies that the user cannot   *
    *                      override the IMS subsystem default for  *
    *                      the PARDLI, IMSOBA, IMSNBA or LOCKMAX   *

    When UAGNS is set to Y and the Region type is set to BMP, an
    addressing error occurs which results in FM/IMS not using the
    correct setting for the following subsystem defaults:
    MAXGN, XDOPTLIB, UPARDLI, UIMSNBA, ULOCKMAX, UAUTOSAV, ULOADFRQ,
    UIEBFREQ, UPROCOPB, UPROCOPP, UPROCOPX and UPROCOPY
    This addressing error causes all the problems listed above.
    

Problem conclusion

  • FM/IMS has been modified to correct all these problems.
