数据迁移_老RAC_新RAC
作者：Eric 微信：loveoracle11g 1、把老集群RAC备份的数据远程拷贝到新集群RAC [root@old-rac-node1 ~]# cd /backup/rman/orcl [root@old-rac-node1 orcl]# ls -l *1119* [root@old-rac-node1 orcl]# scp *1119* [email protected]:/backup/rman/orcl 密码：oracle [root@rac-node1 ~]# su - oracle [oracle@rac-node1 ~]$ cd /backup/rman/orcl [oracle@rac-node1 orcl]$ ll total 7357616 -rw-r----- 1 oracle asmadmin 242676224 Nov 16 02:55 arch_5dtiajdc_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 241586176 Nov 16 02:55 arch_5etiajdc_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 203652096 Nov 16 02:55 arch_5ftiajdg_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 19202048 Nov 16 02:55 ctl_file_5gtiajdi_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 5939224576 Nov 16 02:56 data_level0_59tiajbk_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 868433920 Nov 16 02:56 data_level0_5atiajbk_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 19202048 Nov 16 02:56 data_level0_5btiajbr_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 98304 Nov 16 02:56 data_level0_5ctiajbu_1_1_20181115.bak -rw-r----- 1 oracle asmadmin 98304 Nov 16 02:56 orcl_spfile_5htiajdl_1_1_20181115.bak [oracle@rac-node1 orcl]$ pwd /backup/rman/orcl 2、新集群要恢复的数据库，要开启归档 # su - grid # srvctl stop database -d orcl ---------------------------------------->node1 # su - oracle # export ORACLE_SID=orcl1 # sqlplus / as sysdba SQL> startup mount ; SQL> alter database archivelog ; ---------------------------------------->node2 # su - oracle # export ORACLE_SID=orcl2 # sqlplus / as sysdba SQL> startup mount ; SQL> alter database archivelog ; ---------------------------------------->node1 SQL> alter database open ; ---------------------------------------->node2 SQL> alter database open ; 3、停掉要恢复的数据库orcl 直接停掉# srvctl stop database -d orcl 查看# su - grid # crs_stat -t -v # crsctl stat res -t [oracle@rac-node1 ~]$ export ORACLE_SID=orcl1 [oracle@rac-node1 ~]$ sqlplus / as sysdba SQL> shutdown immediate ; [oracle@rac-node2 ~]$ export ORACLE_SID=orcl2 [oracle@rac-node2 ~]$ sqlplus / as sysdba SQL> shutdown immediate ; [oracle@rac-node1 orcl]$ rman target / RMAN> shutdown immediate ; RMAN> startup mount ; 4、恢复参数文件spfile RMAN> restore spfile to '+DATA/spfileorcl.ora' from '/backup/rman/orcl/orcl_spfile_5htiajdl_1_1_20181115.bak'; RMAN> shutdown immediate ; RMAN> exit ; [oracle@rac-node1 orcl]$ sqlplus / as sysdba SQL> startup force nomount ; ALTER SYSTEM SET DB_CREATE_FILE_DEST='+DATA' SID='*'; ALTER SYSTEM SET DB_RECOVERY_FILE_DEST_SIZE=100G SID='*'; ALTER SYSTEM SET DB_RECOVERY_FILE_DEST='+FRA' SID='*'; ALTER SYSTEM SET CONTROL_FILES='+DATA','+FRA' SCOPE=SPFILE SID='*'; 5、恢复控制文件controlfile [oracle@rac-node1 orcl]$ rman target / RMAN> startup force nomount ; RMAN> restore controlfile from '/backup/rman/orcl/ctl_file_5gtiajdi_1_1_20181115.bak' ; RMAN> alter database mount ; 6、恢复数据文件datafile RMAN> catalog start with '/backup/rman/orcl/' ; 输入：yes run { allocate channel c1 device type DISK; allocate channel c2 device type DISK; allocate channel c3 device type DISK; allocate channel c4 device type DISK; restore database; switch datafile all; switch tempfile all; recover database delete archivelog; release channel c1; release channel c2; release channel c3; release channel c4; } RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of recover command at 11/23/2018 04:04:48 RMAN-06054: media recovery requesting unknown archived log for thread 2 with sequence 1939 and starting SCN of 105650523 run { allocate channel c1 device type DISK; allocate channel c2 device type DISK; allocate channel c3 device type DISK; allocate channel c4 device type DISK; set until sequence 1939 thread 2; # 问题在这 restore database; switch datafile all; switch tempfile all; recover database delete archivelog; release channel c1; release channel c2; release channel c3; release channel c4; } 7、重命名redolog文件 SQL> set linesize 200 ; SQL> select 'alter database rename file '''||MEMBER||''' to '''||'+data/orcl/onlinelog/'||regexp_substr(MEMBER,'[^\/]+',1,4)||''';' from v$logfile;
