Error description

  • This APAR will limit the scope of the optimization added in
    IZ36539, which attempts to push down group-by subquery through
    outer-join subquery, when all of the following conditions are
    met -
    
    1. Database Partitioning Feature (DPF)
    2. Group-by subquery is not a scalar subquery.
    3. The group-by subquery and outer-join subquery are fed to a
       common inner join operator. This inner join operator has at
       least another input stream, called subq3.
    4. Group-by subquery and subq3 have equality join predicate.
