1) Set the Oracle data dictionary export path parameter (optional)
shutdown immediate
alter system set UTL_FILE_DIR='/opt/oracle/utl' scope=spfile;
execute dbms_logmnr_d.build(dictionary_filename => 'logminer_dict.ora', dictionary_location => '/opt/oracle/utl');
startup
2) Add redo log files that need to be analyzed (online archives are available)
execute dbms_logmnr.add_logfile(LogFileName=>'/opt/oracle/OraBase/oradata/inomc/redo01.log', options=>dbms_logmnr.new);
execute dbms_logmnr.add_logfile(LogFileName=>'/opt/oracle/OraBase/oradata/inomc/redo02.log', options=>dbms_logmnr.new);
execute dbms_logmnr.add_logfile(LogFileName=>'/opt/oracle/OraBase/oradata/inomc/redo03.log', options=>dbms_logmnr.new);
3) Execute log loading
use data dictionary
execute dbms_logmnr.start_logmnr(DictFileName=> '/opt/oracle/utl/logminer_dict.ora') ;
Use an online dictionary
execute dbms_logmnr.start_logmnr(Options=>dbms_logmnr.DICT_FROM_ONLINE_CATALOG) ;
4) View the log
SELECT sql_redo FROM v$logmnr_contents;
5) End the analysis and uninstall the log
execute dbms_logmnr.end_logmnr;
