Syntax options:

    LOGGING | NOLOGGING

    The LOGGING clause specifies that updates to new index partitions
    should be logged in the recovery-unit journal file (.ruj) and
    after-image journal file (.aij).

    The NOLOGGING clause specifies that updates to new index
    partitions should not be logged in the recovery-unit journal
    file (.ruj) and after-image journal file (.aij).

    If no store clause is used, then these attributes provide the
    setting for the ALTER INDEX statement.

    The LOGGING and NOLOGGING clauses are mutually exclusive; specify
    only one. The LOGGING clause is the default.
