This section provides several examples of using LogMiner in each of the following general categories:
Examples of Mining by Explicitly Specifying the Redo Log Files of Interest
Examples of Mining Without Specifying the List of Redo Log Files Explicitly
All examples in this section assume that minimal supplemental logging has been enabled:
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
See "Supplemental Logging" for more information.
All examples, except "Example 2: Mining the Redo Log Files in a Given SCN Range" and the "Example Scenarios", assume that the NLS_DATE_FORMAT
parameter has been set as follows:
SQL> ALTER SESSION SET NLS_DATE_FORMAT = 'dd-mon-yyyy hh24:mi:ss';
Because LogMiner displays date data using the setting for the NLS_DATE_FORMAT
parameter that is active for the user session, this step is optional. However, setting the parameter explicitly lets you predict the date format.
