目標DB:Oracle Database 12.1.0.2
一、準備工作
1、查詢當前SCN
成都創(chuàng)新互聯(lián)公司主要從事
成都做網站、成都網站建設、網頁設計、企業(yè)做網站、公司建網站等業(yè)務。立足成都服務白銀,十年網站建設經驗,價格優(yōu)惠、服務專業(yè),歡迎來電咨詢建站服務:028-86922220col current_scn form 99999999999999
SQL> select current_scn from v$database;
CURRENT_SCN
---------------
5965538762695
2、顯示當前DBID和DBName
SQL> select dbid,name from v$database;
DBID NAME
---------- ---------
357998902 PROD
3、對當前重做日志進行歸檔
ALTER SYSTEM ARCHIVE LOG CURRENT;
注:ALTER SYSTEM ARCHIVE LOG CURRENT; 可以保證數(shù)據(jù)的一致性,而Alter system switch logfile;不能保證數(shù)據(jù)一致性。
4、準備備份數(shù)據(jù)
(1)0級備份,1級增量備份,備份時產生的FRA文件
(2)備份ARCHIVELOG 文件
(3)備份參數(shù)文件,命令:backup spfile format '/backup/rman_backup/spfile%d_%s_%p_%u.%'
mkdir -p /mnt/data/backup/PBF/archive
注:(1)的文件傳輸?shù)?mnt/data/backup/PBF
(2)的文件傳輸?shù)?mnt/data/backup/PBF/archive
二、異機恢復步驟
1、創(chuàng)建密碼文件
orapwd file=/mnt/data/PBF/db/12.1.0/dbs/orapwPROD password=oracle entrie=5 format=12
2、準備環(huán)境和initPROD.ora
export ORACLE_SID=PROD
echo $ORACLE_SID
vi initPROD.ora
db_name = PROD
3、將數(shù)據(jù)庫啟動到nomount狀態(tài)
sqlplus / as sysdba
startup nomount pfile=/mnt/data/PBF/db/12.1.0/dbs/initPROD.ora;
or
startup nomount;
4、恢復參數(shù)文件并修改參數(shù)文件
rman target /
restore spfile to pfile '/mnt/data/PBF/db/12.1.0/dbs/initPROD2.ora' from '/mnt/data/backup/PBF/spfilePROD_2402_1_b2stkm1i';
(1)創(chuàng)建路徑:
mkdir -p /mnt/data/PBF/db/archive
mkdir -p /mnt/data/PBF/db/db_recovery_dest
(2)修改pfile中的以下參數(shù):
control_files
diagnostic_dest
db_recovery_file_dest
(3)重新啟動
shutdown abort;
startup nomount;
5、恢復控制文件,修改數(shù)據(jù)庫到mount狀態(tài),并交叉檢查備份集
rman target /
restore controlfile from '/mnt/data/backup/PBF/cntrl_20180312.ctl';
alter database mount;
crosscheck backupset;
6、注冊備份集文件和FRA中的文件,交叉檢查備份集,并刪除過期的備份集
catalog start with '/mnt/data/backup/PBF/';
crosscheck backupset;
delete noprompt expired backupset;
7、注冊archivelog
CATALOG archivelog '/mnt/data/backup/PBF/archive/1_2213_946160568.dbf','/mnt/data/backup/PBF/archive/1_2214_946160568.dbf','/mnt/data/backup/PBF/archive/1_2215_946160568.dbf','/mnt/data/backup/PBF/archive/1_2216_946160568.dbf','/mnt/data/backup/PBF/archive/1_2217_946160568.dbf','/mnt/data/backup/PBF/archive/1_2218_946160568.dbf','/mnt/data/backup/PBF/archive/1_2219_946160568.dbf','/mnt/data/backup/PBF/archive/1_2220_946160568.dbf','/mnt/data/backup/PBF/archive/1_2221_946160568.dbf','/mnt/data/backup/PBF/archive/1_2222_946160568.dbf';
8、由于路徑不一樣,使用以下語句批量生成
select 'set newname for datafile '|| file_id || ' to ''/mnt/data/PBF/db/proddata/' ||
substr(name,
instr(name,'/', -1) + 1) || ''';'
from v$datafile
order by file#;
9、在rman中執(zhí)行以下腳本
run
{
allocate channel ch2 device type disk;
allocate channel ch3 device type disk;
allocate channel ch4 device type disk;

10、聯(lián)機在線日志的處理
(1)生成處理腳本查詢:
set linesize 180 pagesize 100
select 'alter database rename file '''||member||''' to ''/mnt/data/PBF/db/proddata/redoXXX.log'';' from v\$logfile;
(2)處理腳本:
alter database rename file '/data/prod/proddata/log02a.dbf' to '/mnt/data/PBF/db/proddata/redo02a.log';
alter database rename file '/data/prod/proddata/log02b.dbf' to '/mnt/data/PBF/db/proddata/redo02b.log';
alter database rename file '/data/prod/proddata/log01a.dbf' to '/mnt/data/PBF/db/proddata/redo01a.log';
alter database rename file '/data/prod/proddata/log01b.dbf' to '/mnt/data/PBF/db/proddata/redo01b.log';
alter database rename file '/data/prod/proddata/log03a.dbf' to '/mnt/data/PBF/db/proddata/redo03a.log';
alter database rename file '/data/prod/proddata/log04a.dbf' to '/mnt/data/PBF/db/proddata/redo04a.log';
alter database rename file '/data/prod/proddata/log05a.dbf' to '/mnt/data/PBF/db/proddata/redo05a.log';
alter database rename file '/data/prod/proddata/log03b.dbf' to '/mnt/data/PBF/db/proddata/redo03b.log';
alter database rename file '/data/prod/proddata/log04b.dbf' to '/mnt/data/PBF/db/proddata/redo04b.log';
alter database rename file '/data/prod/proddata/log05b.dbf' to '/mnt/data/PBF/db/proddata/redo05b.log';
11、臨時表空間文件的處理
(1)生成處理腳本查詢:
set linesize 180 pagesize 100
select 'alter database rename file '''||name||''' to ''/mnt/data/PBF/db/proddata/tempXXX.dbf'';' from v$tempfile;
(2)處理腳本:
alter database rename file '/data/prod/proddata/temp11.dbf' to '/mnt/data/PBF/db/proddata/temp11.dbf';
alter database rename file '/data/prod/proddata/temp21.dbf' to '/mnt/data/PBF/db/proddata/temp21.dbf';
alter database rename file '/data/prod/proddata/temp12.dbf' to '/mnt/data/PBF/db/proddata/temp12.dbf';
alter database rename file '/data/prod/proddata/temp22.dbf' to '/mnt/data/PBF/db/proddata/temp22.dbf';
alter database rename file '/data/prod/proddata/temp32.dbf' to '/mnt/data/PBF/db/proddata/temp32.dbf';
alter database rename file '/data/prod/proddata/temp42.dbf' to '/mnt/data/PBF/db/proddata/temp42.dbf';
alter database rename file '/data/prod/proddata/temp13.dbf' to '/mnt/data/PBF/db/proddata/temp13.dbf';
alter database rename file '/data/prod/proddata/temp33.dbf' to '/mnt/data/PBF/db/proddata/temp33.dbf';
alter database rename file '/data/prod/proddata/temp43.dbf' to '/mnt/data/PBF/db/proddata/temp43.dbf';
alter database rename file '/data/prod/proddata/temp31.dbf' to '/mnt/data/PBF/db/proddata/temp31.dbf';
alter database rename file '/data/prod/proddata/temp41.dbf' to '/mnt/data/PBF/db/proddata/temp41.dbf';
12、處理 redolog重建時出現(xiàn)的 ORA-00312錯誤
SQL> alter database open resetlogs;
alter database open resetlogs *
ERROR at line 1:
ORA-00392: log 4 of thread 1 is being cleared, operation not allowed
ORA-00312: online log 4 thread 1: '/mnt/data/PBF/db/proddata/redo04a.log'
ORA-00312: online log 4 thread 1: '/mnt/data/PBF/db/proddata/redo04b.log'
(1)查詢redolog文件及其狀態(tài)
col group# form 99
col bytes form 99999999999
col status form a20
select group#,bytes/1024/1024||'M',status from v$log;
(2)修改redolog文件的狀態(tài)
alter database clear logfile group 1;
alter database clear logfile group 2;
alter database clear logfile group 3;
alter database clear logfile group 4;
alter database clear logfile group 5;
(3)再次確認其狀態(tài)
select group#,bytes/1024/1024||'M',status from v$log;
13、使用resetlogs方式打開
SQL> alter database open resetlogs;
14、創(chuàng)建新的spfile文件
create spfile from pfile;
15、重新啟動并備份數(shù)據(jù)庫
