這篇文章主要介紹了怎么把Oracle數據庫從RAC集群遷移到單機環境的相關知識，內容詳細易懂，操作簡單快捷，具有一定借鑒價值，相信大家閱讀完這篇怎么把Oracle數據庫從RAC集群遷移到單機環境文章都會有所收獲，下面我們一起來看看吧。
1、源數據庫
db_name：hisdb SID：hisdb1、hisdb2 IP: 192.168.1.101、192.168.1.102 os：CentOS Linux release 7.3.1611 (Core)
2、目標數據庫
IP: 192.168.1.15 os：CentOS Linux release 7.3.1611 (Core) 安裝 Oracle 軟件， 不創建實例
1、創建 pfile 文件
SQL> create pfile='/home/oracle/pfile0728.ora' from spfile; File created.
2、查看生成的 pfile 文件
[oracle@rac1 ~]$ pwd /home/oracle [oracle@rac1 ~]$ ll total 2487204 drwxr-xr-x 2 oracle oinstall 111 Jun 24 21:30 data-bak drwxr-xr-x 7 oracle oinstall 136 Aug 27 2013 database -rw-r--r--. 1 oracle oinstall 1395582860 Jan 7 2020 p13390677_112040_Linux-x86-64_1of7.zip -rw-r--r--. 1 oracle oinstall 1151304589 Jan 7 2020 p13390677_112040_Linux-x86-64_2of7.zip -rw-r--r-- 1 oracle asmadmin 1547 Jul 28 08:27 pfile0728.ora
3、將 pfile 文件傳到目標數據庫的 $ORACLE_HOME/dbs/ 目錄下
[oracle@rac1 ~]$ scp pfile0728.ora oracle@192.168.1.15:/home/oracle/ The authenticity of host '192.168.1.15 (192.168.1.15)' can't be established. ECDSA key fingerprint is 5c:31:ec:3c:ee:9c:6d:22:f3:60:dc:15:72:fd:67:91. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.1.15' (ECDSA) to the list of known hosts. oracle@192.168.1.15's password: pfile0728.ora 100% 1547 1.5KB/s 00:00 [oracle@rac1 ~]$ # 切換到目標主機 [oracle@mysql bin]$ cd ~ [oracle@mysql ~]$ ls db_install.rsp pfile0728.ora [oracle@mysql ~]$ cp pfile0728.ora $ORACLE_HOME/dbs/ [oracle@mysql ~]$ ls $ORACLE_HOME/dbs/p* /usr/local/oracle/product/11.2.0/db_1/dbs/pfile0728.ora
4、備份源數據庫
（1）創建備份目錄
[root@rac1 ~]# mkdir /arch/bk0729 -p [root@rac1 ~]# chown -R oracle:oinstall /arch/bk0729 [root@rac1 ~]# ll /arch/ 總用量 0 drwxr-xr-x 2 oracle oinstall 6 7月 30 18:58 bk0729
（2）用RMAN 全備數據庫：
#=設置備份參數：備份到磁盤，6 個通道 ====================================== configure device type disk parallelism 6 backup type to backupset; #=設置備份參數：設置備份文件的位置及文件名格式 ================================== configure channel device type disk format '/arch/bk0729/%d_%I_%s_%p_%T.bkp';

1、修改參數文件
（1）源數據庫的參數文件內容如下：
[oracle@rac1 ~]$ vi pfile0728.ora hisdb2.__db_cache_size=192937984 hisdb1.__db_cache_size=201326592 hisdb2.__java_pool_size=4194304 hisdb1.__java_pool_size=4194304 hisdb2.__large_pool_size=8388608 hisdb1.__large_pool_size=8388608 hisdb1.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment hisdb2.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment hisdb2.__pga_aggregate_target=222298112 hisdb1.__pga_aggregate_target=222298112 hisdb2.__sga_target=419430400 hisdb1.__sga_target=419430400 hisdb2.__shared_io_pool_size=0 hisdb2.__db_cache_size=192937984 hisdb1.__db_cache_size=201326592 hisdb2.__java_pool_size=4194304 hisdb1.__java_pool_size=4194304 hisdb2.__large_pool_size=8388608 hisdb1.__large_pool_size=8388608 hisdb1.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment hisdb2.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment hisdb2.__pga_aggregate_target=222298112 hisdb1.__pga_aggregate_target=222298112 hisdb2.__sga_target=419430400 hisdb1.__sga_target=419430400 hisdb2.__shared_io_pool_size=0 hisdb1.__shared_io_pool_size=0 hisdb2.__shared_pool_size=201326592 hisdb1.__shared_pool_size=192937984 hisdb2.__streams_pool_size=0 hisdb1.__streams_pool_size=0 # 以上內容全部刪除 # 創建如下目錄 mkdir -p /usr/local/oracle/admin/hisdb/adump mkdir -p /usr/local/oracle/controlfile/ mkdir -p /data/oracle/controlfile/ mkdir -p /data/oracle/flash_recovery_area mkdir -p /data/oracle/arch mkdir -p /data/oracle/oradata # *.audit_file_dest='/u01/app/oracle/admin/hisdb/adump' --修改此行內容如下 *.audit_file_dest='/usr/local/oracle/admin/hisdb/adump' # *.cluster_database=TRUE # 刪除此行 # *.cluster_database_instances=2 # 刪除此行 *.compatible='11.2.0.4.0' # 此行不變 #*.control_files='+DATA/hisdb/controlfile/control01.ctl','+BAK/hisdb/controlfile/control02.ctl' --修改此行內容如下 *.control_files='/usr/local/oracle/controlfile/control01.ctl','/data/oracle/controlfile/control02.ctl' *.db_block_size=8192 # 此行不變 # *.db_create_file_dest='+DATA' # 刪除此行 # *.db_domain='' # 刪除此行 *.db_name='hisdb' # 此行不變 # *.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area' --修改此行內容如下 *.db_recovery_file_dest='/data/oracle/flash_recovery_area' *.db_recovery_file_dest_size=4102029312 # 此行不變 #*.diagnostic_dest='/u01/app/oracle' --修改此行內容如下 *.diagnostic_dest='/usr/local/oracle' *.dispatchers='(PROTOCOL=TCP) (SERVICE=hisdbXDB)' # 此行不變 # hisdb1.instance_number=1 # 刪除此行 # hisdb2.instance_number=2 # 刪除此行 # *.log_archive_dest_1='location=+BAK' --修改此行內容如下 *.log_archive_dest_1='location=/data/oracle/arch' *.log_archive_format='%t_%s_%r.dbf # *.memory_target=638588928 # 刪除此行 *.open_cursors=300 # 此行不變 *.processes=150 # 此行不變 #*.remote_listener='my-racscan:1521' # 刪除此行 *.remote_login_passwordfile='EXCLUSIVE' # hisdb1.thread=1 # 刪除此行 # hisdb2.thread=2 # 刪除此行 *.undo_tablespace='UNDOTBS1' # 此行不變 # hisdb1.undo_tablespace='UNDOTBS1' # 刪除此行 # hisdb2.undo_tablespace='UNDOTBS2' # 刪除此行
（2）修改后的參數文件內容如下：
*.audit_file_dest='/usr/local/oracle/admin/hisdb/adump'
*.compatible='11.2.0.4.0'
*.control_files='/usr/local/oracle/controlfile/control01.ctl','/data/oracle/controlfile/control02.ctl'*.db_block_size=8192

*.db_file_name_convert=('+DATA/hisdb/datafile','/data/oracle/oradata')
*.db_file_name_convert=('+DATA/hisdb/tempfile','/data/oracle/oradata')2、使用修改后的參數文件啟動數據庫到 nomount
SQL> startup nomount pfile='/home/oracle/pfile0729.ora'; ORACLE instance started. Total System Global Area 233861120 bytes Fixed Size 2251976 bytes Variable Size 176161592 bytes Database Buffers 50331648 bytes Redo Buffers 5115904 bytes
3、生成 spfile 文件，關閉數據庫，然后重新啟動到 nomount
SQL> create spfile from pfile='/home/oracle/pfile0729.ora'; File created. SQL> shutdown immediate; ORA-01507: database not mounted ORACLE instance shut down. SQL> startup m SP2-0714: invalid combination of STARTUP options SQL> startup nomount; ORACLE instance started.

4、啟動 rman，恢復控制文件
[oracle@host-192-168-20-5 oracle]$ rman target / Recovery Manager: Release 11.2.0.4.0 - Production on Sun Jul 31 00:20:01 2022 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. connected to target database: HISDB (not mounted) -- 恢復控制文件 RMAN> restore controlfile from '/data/backup/control_bak_331659.bak'; Starting restore at 31-JUL-22 using target database control file instead of recovery catalog allocated channel: ORA_DISK_1 channel ORA_DISK_1: SID=189 device type=DISK channel ORA_DISK_1: restoring control file channel ORA_DISK_1: restore complete, elapsed time: 00:00:15 output file name=/usr/local/oracle/controlfile/control01.ctl output file name=/data/oracle/controlfile/control02.ctl Finished restore at 31-JUL-22
5、啟動數據庫到 mount
SQL> alter database mount; Database altered.
6、查看控制文件中的數據文件與臨時文件信息
RMAN> report schema;
1、核對備份文件

}6、修改日志文件
（1）查看日志文件
SQL> select member from v$logfile; MEMBER -------------------------------------------------------------------------------- /data/oracle/data/group_601 /data/oracle/data/group_501 /data/oracle/data/group_201 /data/oracle/data/group_101 /data/oracle/data/group_301 /data/oracle/data/group_401 /data/oracle/data/group_701 /data/oracle/data/group_801 /data/oracle/data/group_2101 /data/oracle/data/group_2201 /data/oracle/data/group_2301 /data/oracle/data/group_2401 /data/oracle/data/group_2501 /data/oracle/data/group_3101 /data/oracle/data/group_3201 /data/oracle/data/group_3301 /data/oracle/data/group_3401 /data/oracle/data/group_3501 18 rows selected.
（2）修改日志文件
alter database rename file '+DATA/hisdb/onlinelog/group_6.267.1034787531' to '/data/oracle/data/group_601'; alter database rename file '+DATA/hisdb/onlinelog/group_5.327.1034787531' to '/data/oracle/data/group_501'; alter database rename file '+DATA/hisdb/onlinelog/group_2.262.1034787531' to '/data/oracle/data/group_201'; alter database rename file '+DATA/hisdb/onlinelog/group_1.270.1034787531' to '/data/oracle/data/group_101'; alter database rename file '+DATA/hisdb/onlinelog/group_3.269.1034787679' to '/data/oracle/data/group_301'; alter database rename file '+DATA/hisdb/onlinelog/group_4.257.1034787679' to '/data/oracle/data/group_401'; alter database rename file '+DATA/hisdb/onlinelog/group_7.272.1034787679' to '/data/oracle/data/group_701'; alter database rename file '+DATA/hisdb/onlinelog/group_8.261.1034787679' to '/data/oracle/data/group_801'; alter database rename file '+DATA/hisdb/onlinelog/group_21.344.1042904185' to '/data/oracle/data/group_2101'; alter database rename file '+DATA/hisdb/onlinelog/group_22.345.1042904185' to '/data/oracle/data/group_2201'; alter database rename file '+DATA/hisdb/onlinelog/group_23.346.1042904185' to '/data/oracle/data/group_2301'; alter database rename file '+DATA/hisdb/onlinelog/group_24.347.1042904187' to '/data/oracle/data/group_2401'; alter database rename file '+DATA/hisdb/onlinelog/group_25.348.1042904187' to '/data/oracle/data/group_2501'; alter database rename file '+DATA/hisdb/onlinelog/group_31.349.1042904199' to '/data/oracle/data/group_3101'; alter database rename file '+DATA/hisdb/onlinelog/group_32.350.1042904199' to '/data/oracle/data/group_3201'; alter database rename file '+DATA/hisdb/onlinelog/group_33.351.1042904199' to '/data/oracle/data/group_3301'; alter database rename file '+DATA/hisdb/onlinelog/group_34.352.1042904199' to '/data/oracle/data/group_3401'; alter database rename file '+DATA/hisdb/onlinelog/group_35.353.1042904201' to '/data/oracle/data/group_3501';
1、打開數據庫
RMAN> alter database open resetlogs; database opened
2、查看 redo log 信息，刪除無效日志組（節點2日志）
SQL> select THREAD#, STATUS, ENABLED from v$thread; THREAD# STATUS ENABLED ---------- ------ -------- 1 OPEN PUBLIC 2 CLOSED PUBLIC SQL> select group# from v$log where THREAD#=2; GROUP# ---------- 3 4 7 8 /* alter database drop logfile group 3; alter database drop logfile group 4; alter database drop logfile group 7; alter database drop logfile group 8; */ SQL> alter database disable thread 2; Database altered. SQL> alter database drop logfile group 3； 2 SQL> alter database drop logfile group 3; Database altered. SQL> alter database drop logfile group 4; Database altered. SQL> alter database drop logfile group 7; Database altered. SQL> alter database drop logfile group 8; Database altered. SQL> select THREAD#, STATUS, ENABLED from v$thread; THREAD# STATUS ENABLED ---------- ------ -------- 1 OPEN PUBLIC SQL> select group#,member from v$logfile; GROUP# MEMBER -------------------------------------------------------------------------------- 6 /data/oracle/data/group_601 5 /data/oracle/data/group_501 2 /data/oracle/data/group_201 1 /data/oracle/data/group_101 SQL> select * from v$log; GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARC ---------- ---------- ---------- ---------- ---------- ---------- --- STATUS FIRST_CHANGE# FIRST_TIM NEXT_CHANGE# NEXT_TIME ---------------- ------------- --------- ------------ --------- 1 1 5 104857600 512 1 NO CURRENT 3.4711E+10 31-JUL-22 2.8147E+14 2 1 2 104857600 512 1 YES INACTIVE 3.4711E+10 31-JUL-22 3.4711E+10 31-JUL-22 5 1 3 104857600 512 1 YES INACTIVE 3.4711E+10 31-JUL-22 3.4711E+10 31-JUL-22 6 1 4 104857600 512 1 YES INACTIVE 3.4711E+10 31-JUL-22 3.4711E+10 31-JUL-22
3、查看 undo 表空間，并刪除節點2的 undo 表空間
SQL> sho parameter undo; NAME TYPE VALUE ------------------------------------ ----------- ------------------------------ undo_management string AUTO undo_retention integer 900 undo_tablespace string UNDOTBS1 SQL> SQL> SQL> SQL> select tablespace_name from dba_tablespaces where contents='UNDO'; TABLESPACE_NAME ------------------------------ UNDOTBS1 UNDOTBS2 SQL> drop tablespace UNDOTBS2 including contents and datafiles; Tablespace dropped.
4、創建臨時表空間
SQL> select tablespace_name from dba_tablespaces where contents='TEMPORARY'; TABLESPACE_NAME ------------------------------ TEMP SQL> create temporary tablespace TEMP1 tempfile '/data/oracle/oradata/temp01.dbf' size 50M; Tablespace created. SQL> alter database default temporary tablespace TEMP1; Database altered. SQL> drop tablespace TEMP including contents and datafiles; Tablespace dropped.
5、重啟數據庫，OK！！
SQL> shutdown immediate Database closed. Database dismounted. ORACLE instance shut down. SQL> startup ORACLE instance started. Total System Global Area 233861120 bytes Fixed Size 2251976 bytes Variable Size 176161592 bytes Database Buffers 50331648 bytes Redo Buffers 5115904 bytes Database mounted. Database opened.
