Problem summary

  • APAR NUMBER:  PJ40907
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  LOADERS
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    A CTL-3 error occurs when the ZDPFS LOG command is issued and
    the positive feedback control record has not been initialized.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/rt/cupv.c
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    (C) base/lib/libCUPV.so
    (C) base/load/CUPV.so
    (C) base/obj/cupv.o
    
    Support Files:
    base/lst/CUPV.map
    base/lst/cupv.lst
    
    OTHER BINARIES TO BUILD: NO
    None.
    
    COMMENTS:
    The do_log subroutine in segment cupv.c uses the number of
    entries per log record in the positive feedback control record
    to calculate the starting and ending log records to use in the
    display. If the positive feedback control record has not been
    initialized yet then a CTL-3 error (fixed point divide
    exception) occurs when attempting to display data entries from
    the log record.
    

Problem conclusion

  • SOLUTION:
    Segment cupv.c has been updated to check if the number of
    entries per log record in the positive feedback control record
    (ac0ipr) is zero. If the value is zero then it means the
    control record has not been initialized and there are no
    entries in the log record. In this case a display of zero log
    entries is shown.
    
    COREQS: NO
    None.
    
    MIGRATION CONSIDERATIONS: NO
    None.
