    ABEND0C4 in DSNSVSFB was issued because a DM workarea's storage
    header had been overlaid.
    Also ABEND04E RC00C90101 DSNIKESR:5008 was issued due to a
    corrupted row made by an UPDATE.
    The tablespace was in BRF. But in an UPDATE process, it was
    treated as RRF partially due to a residual flag and it caused
    variable problems.
    Also abend04E RC00E20992 DSNSVSVB+0E2E

    An uninitialized bit indicated that the row was in Reordered
    Row Format when it was in Basic Row Format. This caused the
    user defined default value for missing varying length columns
    to be returned without the 2-byte length preceding the data.
    The user defined data was then interpreted by DB2 to be the
    length of the data that followed.
    

Problem conclusion

  • DB2 code is fixed to initialize the row format bit properly.
