Problem summary

  • APAR NUMBER:  PM82546
    PRODUCT:  z/TPFDF
    FUNCTIONAL AREA:  TPFDF CENTRAL DATABASE ROUTINES
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    With PK70512 applied, deleting a type-2 large logical record
    (LLR) can result in lost addresses.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) tpfdf/rt/ufka03.cpp
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    None.
    
    Support Files:
    None.
    
    OTHER BINARIES TO BUILD: YES
    (C) <sys>/obj/ufka03.o
    (C) <sys>/load/UFKA.so
    
    COMMENTS:
    When a large logical record (LLR) is deleted, the LLR release
    processing creates a child ECB with a copy of the large LREC
    interface block (LLIB) containing the large LREC data block
    (LLDB) addresses to release. The LLIB copy is erroneously set
    up with the length of the blocktype value L4 (0x51) instead of
    the correct 4K blocksize (_GBSZE, defined as 4095). All LLDB
    references in the core block starting at displacement 0x52 up
    to the end of the block are then not released and will show up
    as lost addresses in recoup.
