Trace
    Notrace

    Specifies that the optimization of the .aij file be traced. The
    default is the Notrace qualifier, where optimization is not
    traced. When optimization is traced, the output from the Trace
    qualifier identifies transactions in the .aij file by transaction
    sequence numbers (TSNs) and describes what Oracle RMU did with
    each transaction during the optimization process. You can specify
    the Log qualifier with the Trace qualifier.
