APAR status

  • Closed as program error.

Error description

  • Only one clustering index is allowed for a table. But if target
    environment already has a clustering index and Source defines
    another clustering index without changing existing index to NOT
    CLUSTER, Object Compare generates incorrect apply job that
    fails with SQLCODE = -623. Object Compare should issue an error
    message when index cannot be defined as clustering index.

    ****************************************************************
    Only one clustering index is allowed for a table. But if the
    target environment already has a clustering index and the source
    defines another clustering index without changing the existing
    index to NOT CLLUSTER, Object Compare generates an incorrect
    apply job that fails with SQLCODE -623. With this APAR, Object
    Compare issues a new error message, ADB7421E, when an index
    cannot be defined as a clustering index.
