rman恢復增長ADG(級聯ADG)

當前已經有一套ADG庫，分別是prod1和prod1s
計劃從pord的ADG備庫(prod1s)拷貝一個0級rman全備到新的服務器，恢復後，搭建成新增的ADG，SID叫prod2s，後面激活當作測試庫

新服務器上設置
export ORACLE_SID=pord2s

從源庫porddb1s生成一個pfile,,拷貝pfile到目標庫
修改相關路徑參數後，而後轉換成spfile

SQL> create spfile from pfile='/pordtestdata/software/pfilepord.ora' ;

 

恢復控制文件
RMAN> shutdown immediate;

RMAN> startup nomount;

RMAN> restore standby controlfile from '/pordtestdata/arch/o1_mf_s_883643262_bs15sq11_.bkp';

RMAN> shutdown immediate;

RMAN> startup mount;

CATALOG命令從新註冊備份集；
RMAN> catalog start with '/pordtestdata/arch';

 

4.開始恢復，在rman備份的源庫(cascaded standby),在本例中爲prod1s庫
RMAN> report schema ;
更加相關信息整理成下面格式

弄成shell腳本後臺執行
$ cat rman1.sh
#!/bin/bash
source .bash_profile
/u01/app/oracle/product/11.2.0/db_1/bin/rman target / <<EOF
run {
set newname for datafile 1 to '/pordtestdata/oradata/system.259.819420143';
set newname for datafile 2 to '/pordtestdata/oradata/sysaux.260.819420151';
set newname for datafile 3 to '/pordtestdata/oradata/undotbs1.261.819420153';
set newname for datafile 4 to '/pordtestdata/oradata/undotbs2.263.819420163';
set newname for datafile 5 to '/pordtestdata/oradata/users.264.819420163';
set newname for datafile 6 to '/pordtestdata/oradata/pord.295.819889851';
...省略N行
set newname for datafile 133 to '/pordtestdata/oradata/pord_idx08.dbf';
set newname for datafile 134 to '/pordtestdata/oradata/pord_idx09.dbf';
set newname for datafile 135 to '/pordtestdata/oradata/pord_idx10.dbf';
set newname for datafile 136 to '/pordtestdata/oradata/pord_idx11.dbf';
set newname for datafile 137 to '/pordtestdata/oradata/pord_idx12.dbf';
set newname for datafile 138 to '/pordtestdata/oradata/pord_idx13.dbf';
set newname for datafile 139 to '/pordtestdata/oradata/tbs_sysaux03.dbf';
restore database;
switch datafile all;
}
EOF
exit ;

 

經過查看視圖 V$SESSION_LONGOPS 這個視圖是查看長時間操做的會話,能夠粗略的分析完成進度，
不但能夠用於rman 也能夠用於impdp/expdp
set linesize 200 ;
select sid,opname,serial#,context,sofar,totalwork,round(sofar/totalwork*100,2) "%_complete"
from v$session_longops
where opname like 'RMAN%'
and opname not like '%aggregate%'
and totalwork != 0
and sofar <> totalwork
order by "%_complete" desc ;

修改pord1s庫上的tns,指向新的目標庫
增長
pord2s =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = prod2s.test.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pord2s)
)
)

處理tempfile
alter database tempfile '/porddata/oradata/temp.262.819420155' drop;

SQL> alter tablespace temp add tempfile '/pordtestdata/oradata/temp1.dbf' size 10G;

 

--alter system set log_archive_config='DG_CONFIG=(pord1,pord1s,pord2s)';

備份原參數:

修改爲下面的:
alter system set log_archive_dest_2='SERVICE=prod2s LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=pord2s';

增長一些新的standby log
ALTER DATABASE ADD STANDBY LOGFILE GROUP 21 '/tmpdata/pordredo/redo_21.log' size 1G;
ALTER DATABASE ADD STANDBY LOGFILE GROUP 22 '/tmpdata/pordredo/redo_22.log' size 1G;
ALTER DATABASE ADD STANDBY LOGFILE GROUP 23 '/tmpdata/pordredo/redo_23.log' size 1G;
ALTER DATABASE ADD STANDBY LOGFILE GROUP 24 '/tmpdata/pordredo/redo_24.log' size 1G;
ALTER DATABASE ADD STANDBY LOGFILE GROUP 25 '/tmpdata/pordredo/redo_25.log' size 1G;

清理舊的
alter database clear logfile group 6;
alter database clear logfile group 7;
alter database clear logfile group 8;
alter database clear logfile group 9;
alter database clear logfile group 10;

alter database clear logfile group 16;
alter database clear logfile group 17;
alter database clear logfile group 18;
alter database clear logfile group 19;
alter database clear logfile group 20;

 

alter database recover managed standby database cancel ;
alter database recover managed standby database disconnect from session;

解決gap，從主庫或者cascade standby庫去找，若是從主庫找到了，須要在備庫註冊，由於日誌是從備庫(cascade standby）發送到目標庫的

RMAN> list archivelog from sequence 74227 until sequence 74231;

scp o1_mf_1_74227_bs0rc32g_.arc 10.45.26.102:/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_29/
scp o1_mf_1_74228_bs0zvxss_.arc 10.45.26.102:/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_29/
scp o1_mf_1_74229_bs11pq4p_.arc 10.45.26.102:/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_29/
scp o1_mf_1_74230_bs1305mk_.arc 10.45.26.102:/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_29/
scp o1_mf_1_74231_bs147yyl_.arc 10.45.26.102:/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_29/

RMAN> catalog start with '/porddata/fast_recovery_area/pordDB1S/archivelog/2015_06_30/';

日誌追的差很少的時候，能夠作failover切換

主庫或者cascade standby庫
alter system set log_archive_dest_state_2=defer;

要激活的standby
alter system set aq_tm_processes=0 scope=memory;
alter database recover managed standby database cancel;
alter database activate physical standby database;
shutdown immediate
startup
select OPEN_MODE,SWITCHOVER_STATUS,DATABASE_ROLE,PROTECTION_MODE
FROM v$database;

 

激活後，恢復生產庫pordadg的log_archive設置alter system set log_archive_dest_2='SERVICE=pord1 LGWR SYNC AFFIRM VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=pord1';alter system set log_archive_dest_state_2=enable;
