Error description

  • Refresh MQT in DPF environement doesn't honor an optimization
    level, previously  set with SET CURRENT OPTIMIZATION LEVEL
    statement. Usually setting lower optimization level is needed to
    avoid MQT routing during MQT refresh operation for a base table
    with number of MQT to reduce locking and increase concurrency.
    Lowering optimization level before REFRESH MQT statement in a
    single node environment works  as expect, however in DPF
    environment current optimization level is not honored by other
    nodes thus having them to compile REFRESH MQT statement at the
    default optimization level (5).
