Error description

  • ABEND0C4 RC003B at DSNXODN OFFSET00600 and ABEND04E RC00E2000D
    at DSNLXDAL DSNSVSFB OFFSET00A18 occurred due to a storage
    overlay and led to Db2 abnormal termination with RC00E50702.
    
    The abend can occur on queries which contain
    1. Left outer join, and
    2. The ON-clause of left outer join has predicates under an
       'OR', and
    3. The outer table of left outer join uses page range screening
    .

    * Apply corrective PTF when available                          *
    ****************************************************************
    The abend occurs when a table eligible for page range
    screening uses the wrong predicate. This occurs when the query
    contains left outer join and the ON-clause contains an 'OR'
    predicate.
