APAR status

  • Closed as program error.

Error description

  • In controller address spaces, if ras_output_outputLocation
    includes 'buffer' then IPCS will be able to format out any
    WebSphere CTRACE data that might be present in the dump.
    
    For 64 bit controller regions, this data does not get formatted
    out.  IPCS issues the following message:
    There are no trace buffers in the dump for COMP(DADPLEX)
    SUB((DADADAC03C4))

    *                  Server V7.0 for z/OS                        *

    * PROBLEM DESCRIPTION: Can not format a controller's ctrace    *
    *                      buffers when the server is running in   *
    *                      64 bit mode.                            *

    * RECOMMENDATION:                                              *
    ****************************************************************
    When IP CTRACE COMP(WAS00) SUB((BBOS0010038)) LOCAL FULL
    is issued against a dump from a controller that was running in
    64 bit mode this messages is returned.
    There are no trace buffers in the dump
    for COMP(WAS00) SUB((BBOS0010038))
    When running in 64 bit mode a glue routine makes a copy of
    the btrc and uses that address when doing the CTRACE DEFINE.
    When trying to format the CTRACE buffers in a dump we get
    the address of the copy and it does not pass validation
    because the storage has been freed and reallocated as
    something else. The btrc is already in 31 bit storage so there
    is no need for the glue routine to make a copy.
    

Problem conclusion

  • Changed the glue routine to not make a copy of the btrc.
    
    APAR PM93642 is currently targeted for inclusion in WebSphere
    Application Server Fix Pack 7.0.0.31.
