Error description

  • Dump Title: DE2A ABND 04E 00C90101 U=STCODPX M=N C=101 EDM
    GEDLC M=DSNTFRCV LOC=DSNGEDM DSNGEPUF 500A
    ABEND04E RC00C90101 DSNGEPUF ERQUAL500A was issued on DB2 V10
    NFM when a big DBD was read while another member was updating
    the DBD.
    The DBD on DSNDB01.SYSDBDXA was correct.
    The DBD was big and split in many sections.
    While one member was reading the DBD, another member updated the
    DBD.
    Then early some sections were read from the old DBD and later
    sections were read from the new DBD.
    Then the read DBD was inconsistent.
    .
    This is a temporary problem. Reread the DBD can finish normally.

    *                      when a DBD is loaded on one member      *

    ****************************************************************
    ABEND04E in DSNGEPUF:500A RC00C90101 was received when a large
    DBD was being loaded on one member and being updated on a
    different member at the same time. The second member could
    update the DBD before the first member completed the read,
    which caused the reported abend or other unpredictable results.
    

Problem conclusion

  • The code has been updated to insure that a member completes a
    DBD read before another member can update the DBD.
