Problem summary

  • APAR NUMBER:  PJ40696
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  DASD
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    Catastrophic CTL-38 possible when FLSPC issued to module in
    copy.
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/cp/cjio.cpy
    
    Object Only Binaries:
    None.
    
    Configuration Independent Binaries:
    None.
    
    Support Files:
    None.
    
    OTHER BINARIES TO BUILD: YES
    (C) <sys>/obj/ccsons.o
    (C) <sys>/load/CPS0.so
    
    COMMENTS:
    During file copy, when IOBs are placed on the copy delay queue,
    the write completions are handled by routine CJIOWRIT. This
    routine does not have logic for a FLSPC however, which causes a
    catastrophic CTL-38 to occur. A FLSPC is not often used by
    z/TPF and the most likely scenario that could cause this is to
    use a ZAFIL with MCHR on a record for the mod in copy. If that
    ZAFIL is sent to the copy delay queue due to either a lock not
    found or copy lock match condition, the CTL-38 may occur. A
    normal ZAFIL will not use FLSPC. A FLSPC is only used when an
    MCHR is specified instead of a normal FARF file address.
