This screen displays an estimate of the time it will take to roll
    back a transaction, or to completely recover a failed process.

                                DISCLAIMER

       The information provided in this screen is an estimate based
       on previous process recovery operations and other factors
       such as page contention and disk throughput.

       Note that this information is an estimate only; the actual
       process recovery duration may be more or less than described
       on this screen.

       Individual process failure recovery performance can vary
       widely depending on many factors which cannot be accounted
       for in the displayed estimate. These factors include lock
       deadlock stalls, network delays, disk contention and many
       other system factors such as lock remastering.

    This screen displays the following fields:

    o  Process.ID - The process identifier of a process that has the
       potential to roll back a transaction or require transaction
       recovery in the event of process failure.

    o  RUJ.Sz - The number of blocks of RUJ information that have
       been written by the process.

    o  Tx.Rollback - The estimate of the time it would require for
       the process to roll back the transaction. Note that this is
       different from the time it would take the DBR process to roll
       back the transaction.

    o  DBR.Tx.Undo - The estimate of the time it would require for
       the DBR process to undo the transaction. The DBR transaction
       undo duration is typically less than it takes the process to
       roll back the transaction, due to various optimizations and
       simplifications in the DBR recovery algorithm.

    o  AIJ.Ckpt - If the fast commit feature is enabled, this is the
       most recent checkpoint location in the AIJ journal for the
       process.

    o  Pnd - If AIJ journaling is enabled, this is the number of
       blocks of AIJ information that have been submitted, but not
       yet written to the AIJ journal.

    o  DBR.Tx.Redo - If the fast commit feature is enabled, this is
       the estimate of the time it would take the DBR process to redo
       the previously committed transactions of the failed process to
       the database.

    o  DB.Freeze.Tm - The estimate of the total time the database
       would be frozen if the current process were to prematurely
       terminate.

    You can use the Config menu option to configure the Transaction
    Recovery Duration Estimate screen. Select this option, by
    typing the letter C, to display the configuration submenu. The
    configuration submenu provides the following options:

    o  Unsorted Display

    o  Sort by oldest transaction rollback

    o  Sort by oldest DBR undo

    o  Sort by oldest DBR redo

    o  Sort by oldest database freeze

    You can examine the past history of recovery operations by
    issuing the RMU Dump Header command and reviewing the Database
    Recovery section.

    The Transaction Recovery Duration Estimate screen is not recorded
    in the binary output file produced using the Output qualifier.
    Consequently, this screen is not available when you replay a
    binary file using the Input qualifier.
