Error description

  • You are IPLing your systems, and as the CICS regions start, you
    receive a number of dumps on DFHPI0001 as follows:
    DFHPI0001 CICS3W3A An abend (code 0C4/AKEA) has occurred at
      offset X'2F02' in module DFHPIWR.
    DFHME0116 (Module:DFHMEME) CICS symptom string for message
      DFHPI0001 is PIDS/5655S9700 LVLS/660 MS/DFHPI0001 RIDS/DFHPIWR
      PTFS/UK57403 AB/S00C4 AB/UAKEA ADRS/00002F02
    .
    Inspection of the code at the address indictated in the dump, at
    DFHPIWR + x'2F02' shows that we are processing a Web Control
    Block (WCB).  Offset x'34' into the WCB is supposed to
    represent PI_WSBCTL_WSR_PTR.  This value has not been properly
    intialized, causing the the ABENDs.

    ****************************************************************
    When a WEBSERVICE resource is installed dynamically, DFHPIWR
    CREATE_WEBSERVICE creates a WCB and attaches CPIR to initialise
    the webservice. CPIR is suspended for a call to DFHDHFS
    INQUIRE_HFS_FILE. At this time, another task is started to
    inquire the same WEBSERVICE. As a WRB has not been allocated,
    pi_wsbctl_wsr_ptr in the WCB is zero. Abend 0C4 is issued when
    CICS uses this pointer to address storage.

Problem conclusion

  • DFHPIWR INQUIRE_WEBSERVICE is changed to check pi_wsbctl_wsr_ptr
    before using it.
