Logminer 數據庫恢復及恢復歸檔文件

1.從源庫生成spfile文件，並拷貝到目標庫
sqlplus '/as sysdba'
create pfile='/oracle/tmp/pfile_dbname1_20130319.ora' from spfile;


2.目標庫使用源庫的pfile文件，去掉相關參數，打開數據庫到nomount狀態
export ORACLE_SID=dbname1
sqlplus '/as sysdba'
startup nomount pfile='/oradata/dbname/pfile_dbname1_20130319.ora'


3.查看備份集，確定控制文件
bplist -t 4 -C db1 -l -R / |more
/c-3869497698-20130317-01


4.還原控制文件
rman target /
set dbid=3869497698
run {
allocate channel ch1 device type sbt parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db1)';
restore controlfile from '/c-3869497698-20130317-01';
}
sql ' alter database mount'


5.檢查恢復的表所在的表空間
SELECT * FROM dba_segments C WHERE C.segment_name='T_WFE_TEMPLATE';
TBS_dbname_WF_DAT


6.設置還原後的文件路徑，使用腳本還原數據庫(核心表空間和必需的業務空間)
select 'set newname for datafile ''' || d.file_name || ''' to ''/oradata/dbname/' || replace(file_name, '/dev/', '') || ''';',
       d.tablespace_name
  from dba_data_files d
 where d.tablespace_name in
       ('SYSTEM', 'UNDOTBS1', 'UNDOTBS2', 'TBS_dbname_WF_DAT')
 order by 2;


$ vi rman_dbname1_restore.sh
export ORACLE_SID=dbname1
CMD_STR_SYS="
rman target / log=/oradata/dbname/rman_dbname1_restore.log << eof
run {
allocate channel ch1 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db1)';
allocate channel ch2 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db2)';
set newname for datafile '/dev/rvg01_system_2g' to '/oradata/dbname/rvg01_system_2g';
set newname for datafile '/dev/rvg01_4g_01' to '/oradata/dbname/rvg01_4g_01';
set newname for datafile '/dev/rvg01_4g_02' to '/oradata/dbname/rvg01_4g_02';
set newname for datafile '/dev/rvg01_4g_03' to '/oradata/dbname/rvg01_4g_03';
set newname for datafile '/dev/rvg01_4g_04' to '/oradata/dbname/rvg01_4g_04';
set newname for datafile '/dev/rvg01_4g_05' to '/oradata/dbname/rvg01_4g_05';
set newname for datafile '/dev/rvg01_4g_06' to '/oradata/dbname/rvg01_4g_06';
set newname for datafile '/dev/rlv_db04_4g_003' to '/oradata/dbname/rlv_db04_4g_003';
set newname for datafile '/dev/rvg03_4g_30' to '/oradata/dbname/rvg03_4g_30';
set newname for datafile '/dev/rlv_db05_4g_027' to '/oradata/dbname/rlv_db05_4g_027';
set newname for datafile '/dev/rlv_db05_4g_013' to '/oradata/dbname/rlv_db05_4g_013';

set newname for datafile '/dev/rlv_db05_4g_023' to '/oradata/dbname/rlv_db05_4g_023';
set newname for datafile '/dev/rlv_db05_10g_007' to '/oradata/dbname/rlv_db05_10g_007';
set newname for datafile '/dev/rlv_db06_10g_006' to '/oradata/dbname/rlv_db06_10g_006';
set newname for datafile '/dev/rlv_db06_10g_009' to '/oradata/dbname/rlv_db06_10g_009';
set newname for datafile '/dev/rlv_db06_4g_031' to '/oradata/dbname/rlv_db06_4g_031';
set newname for datafile '/dev/rlv_db06_10g_023' to '/oradata/dbname/rlv_db06_10g_023';
set newname for datafile '/dev/rlv_db06_4g_039' to '/oradata/dbname/rlv_db06_4g_039';
set newname for datafile '/dev/rlv_db06_4g_040' to '/oradata/dbname/rlv_db06_4g_040';
set newname for datafile '/dev/rlv_db06_4g_041' to '/oradata/dbname/rlv_db06_4g_041';
set newname for datafile '/dev/rlv_db07_10g_07' to '/oradata/dbname/rlv_db07_10g_07';
set newname for datafile '/dev/rlv_db07_10g_23' to '/oradata/dbname/rlv_db07_10g_23';
set newname for datafile '/dev/rvg02_undo_30g_1' to '/oradata/dbname/rvg02_undo_30g_1';
set newname for datafile '/dev/rvg02_undo_30g_2' to '/oradata/dbname/rvg02_undo_30g_2';
restore tablespace system,UNDOTBS1,UNDOTBS2,TBS_dbname_WF_DAT;
switch datafile all;
}
exit
eof
"
sh -c "$CMD_STR_SYS" >> /oradata/dbname/rman_dbname1_restore.log &


$ nohup sh rman_dbname1_restore.sh &
$ tail -50f rman_dbname1_restore.out


7.設置redo的路徑
select 'alter database rename file ''' || d.MEMBER || ''' to ''/oradata/dbname/' || replace(d.MEMBER, '/dev/', '') || ''';' sSQL
  from v$logfile d


sqlplus '/as sysdba'
alter database rename file '/dev/rvg01_redo11_512' to '/oradata/dbname/rvg01_redo11_512';
alter database rename file '/dev/rvg02_redo21_512' to '/oradata/dbname/rvg02_redo21_512';
alter database rename file '/dev/rvg01_redo12_512' to '/oradata/dbname/rvg01_redo12_512';
alter database rename file '/dev/rvg02_redo22_512' to '/oradata/dbname/rvg02_redo22_512';
alter database rename file '/dev/rvg01_redo13_512' to '/oradata/dbname/rvg01_redo13_512';
alter database rename file '/dev/rvg02_redo23_512' to '/oradata/dbname/rvg02_redo23_512';
alter database rename file '/dev/rvg01_redo14_512' to '/oradata/dbname/rvg01_redo14_512';
alter database rename file '/dev/rvg02_redo24_512' to '/oradata/dbname/rvg02_redo24_512';


8.恢復數據庫到制定的時間點，並skip掉不需要的表空間
$ vi rman_dbname1_recover.sh
CMD_STR_RECOVER="
rman target / log=/oradata/dbname/rman_dbname1_recover.log << eof
run {
allocate channel ch1 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db1)';
allocate channel ch2 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db2)';
set until time \"TO_DATE('2013-03-15 03:00:00','YYYY-MM-DD HH24:MI:SS')\";
recover database skip forever tablespace 'PERFSTAT','PRECISE_OR_TAB','TBS_dbname_BS_DAT','TBS_dbname_BS_HISDAT','TBS_dbname_BS_HISIDX','TBS_dbname_BS_IDX','TBS_dbname_BS_TEMP','TBS_dbname_ESALES_DAT','TBS_dbname_ESALES_HISDAT','TBS_dbname_ESALES_IDX','TBS_dbname_ESALES_LOGDAT','TBS_dbname_ESALES_LOGIDX','TBS_dbname_MKT_DAT','TBS_dbname_MKT_HISDAT','TBS_dbname_MKT_HISIDX','TBS_dbname_MKT_IDX','TBS_dbname_RPT_DAT','TBS_dbname_RPT_IDX','TBS_dbname_WF_HISDAT','TBS_dbname_WF_HISIDX','TBS_dbname_WF_IDX','TBS_dbname_WF_TEMP','TS_IDX_KFMAIN_dbname_01','TS_TAB_KFMAIN_dbname_01','TS_TAB_VERITAS_DATA','USERS';
RELEASE CHANNEL ch1;
RELEASE CHANNEL ch2;
}
exit
eof
"
sh -c "$CMD_STR_RECOVER" >> /oradata/dbname/rman_dbname1_recover.log


9.根據還原的時間點和恢復的截止時間點，查看需要多少歸檔文件
select * from v$log_history d where d.FIRST_TIME> Date'2013-03-14'+23/24 and d.FIRST_TIME< Date'2013-3-16'


10.打開數據庫，並查詢需要恢復的標的數據
sqlplus '/as sysdba'
alter database open resetlogs


select count(*) from icdwf.t_wfe_template;


11.生成logminer的相關包和視圖
@?/rdbms/admin/dbmslm.sql
@?/rdbms/admin/dbmslmd.sql


12.還原logminer需要的歸檔文件(此處需要使用open之前的控制文件來mount數據庫，需要做好備份)
startup mount pfile='/oracle/dbname/archlog01/pfile_dbname1_20130319_arc.ora';


--恢復歸檔
run {
allocate channel ch1 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db1)';
restore archivelog from logseq 48041 until logseq 48045 thread 1;
}
run {
allocate channel ch1 type 'sbt' parms='ENV=(NB_ORA_SERV=bakserver,NB_ORA_CLIENT=db2)';
restore archivelog from logseq 64951 until logseq 64960 thread 2;
}


--添加數據字典文件
alter system set utl_file_dir='/oradata/dbname/logminer' scope=spifle;


begin
 sys.dbms_logmnr_d.build(dictionary_filename=>'dictionary.ora', dictionary_location =>'/oradata/dbname/logminer');

end;


select db_name, thread_sqn,filename from v$logmnr_logs;


--開始挖掘
