1. Preparation: Check if there is a writable directory: SQL> show parameter UTL

Name Type Value --------------------------------- --------------------- UTL_FILE_DIR STRING

It can be seen that the current parameter file does not specify a writable directory, you need to shutddown Immediate Database, then add the UTL_FILE_DIR = 'c: / temp' parameter in the parameter file, this parameter is a static parameter, so you must turn off the database for modification, if Use the alter system set command to make an error: SQL> ALTER system set UTL_FILE_DIR = 'c: / temp'; alter system set utl_file_dir = 'c: / temp' * error is in Chapter 1: ORA-02095: Unable to modify the designated Initialization parameters

After modifying the parameter file, use Startup Pfile = '% Oracle_home / pfile / init.ora' to launch the database, then start the database in order to start according to the default mode, ie STARTUP, you need to modify the spfile file: create spfile from pfile = '% Oracle_home /pfile/init.ora '; usually need to be a spfile backup: create spfile ='% oracle_home / pfile / spinit.ora '; from pfile ='% oracle_home / pfile / init.ora '; now modify it now It can be seen by the following search: SQL> Show parameter UTL

Name Type Value --------------------------------- ----------------------------- UTL_FILE_DIR STRING C: / TEMPSQL> Show Parameter SPFile

Name Type Value --------------------------------- -------------------------------- SPFILE STRING% Oracle_Home% / Database / SPFILE% ORACLE_SID%. ORA

Below, if you log in with SYS users, check if there is a package below: SQL> DESC SYS.DBMS_LOGMNR_DELEMENT TYPE ------------------------- store_in_flat_file Constant store_indo_logs constant build procedure set_tablespace procedure seems to be existing, generally default installation will have, huh, if not, you need to run $ oracle_home / rdbms / admin / dbmslmd.sql

SQL> It seems that it will exist, generally the default installation will have, huh, if not, you need to run $ oracle_home / rdbms / admin / dbmslm.sql

Then, extract the data dictionary directly to a specified planar file: SQL> EXEC DBMS_LOGMNR_D.BUILD ('data_dicitonary.ora', 'c: / temp', options => dbms_logmnr_d.store_in_flat_file);

PL / SQL Procedure SuccessFully Completed

SQL>

If not a SYS user, you need to display a user who uses LogMiner to grant a permissions and a role: SQL> Grant Execute on sys.dbms_logmnr to lunar; authorized success.

SQL> Grant Execute_catalog_role to lunar;

Authorized success.

SQL>

SQL> Conn Lunar / Lunarconnected to Oracle9i Enterprise Edition Release 9.2.0.1.0 Connected As Lunar

SQL> Show useruser is "lunar"

SQL> EXEC SYS.DBMS_LOGMNR_D.BUILD ('data_dicitonary_lunar.ora', 'c: / temp', options => sys.dbms_logmnr_d.store_in_flat_file);

PL / SQL Procedure SuccessFully Completed

Ok, you can analyze it now.

2. Creating an Analysis Log List To create a available re-analyzer day, you need to run dbms_logmnr.add_logfile: sql> execute sys.dbms_logmnr.add_logfile (logfilename => 'E: /oraclename =>' e: /oraclename => ' ', options => sys.dbms_logmnr.new);

The table has been changed.

SQL> INSERT INTO TEST VALUES 2 (To_Char (Sysdate, 'YYYY-MM-DD HH24: MM: SS'), 'Lunar');

SQL> commit;

SQL> SELECT *.

3. Start analysis Day to first set the date time format: SQL> ALTER SESSION SET NLS_DATE_FORMAT = 'YYYY-MM-DD: HH24: MI: SS;'

Session altered

SQL>

SQL> execute sys.dbms_logmnr.start_logmnr (DictFileName => 'C: /TEMP/Data_dicitonary_lunar.ora');

Now, you can query the V $ logmnr_contents data dictionary and analyze the database system. SQL> DESC V $ logmnr_contents
