本文主要是介绍oracle10g_rac迁移单机，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1.创建与rac主机备份相同的目录
| [root@sec1 ~]# cd /u01/backup/ [root@sec1 backup]# ll total 616112 -rw-r--r-- 1 root root 17510400 Aug 2 15:28 arch_11qdjhkm_1_1_20150802 -rw-r--r-- 1 root root 11666432 Aug 2 15:28 arch_12qdjhkm_1_1_20150802 -rw-r--r-- 1 root root 15335424 Aug 2 15:28 ctl_file_14qdjhks_1_1_20150802 -rw-r--r-- 1 root root 23183360 Aug 2 15:28 suys_lev0_0pqdjhj7_1_1_20150802 -rw-r--r-- 1 root root 8388608 Aug 2 15:28 suys_lev0_0qqdjhj7_1_1_20150802 -rw-r--r-- 1 root root 933888 Aug 2 15:28 suys_lev0_0rqdjhj8_1_1_20150802 -rw-r--r-- 1 root root 553115648 Aug 2 15:29 suys_lev0_0sqdjhj8_1_1_20150802 -rw-r--r-- 1 root root 98304 Aug 2 15:28 suys_spfile_15qdjhkv_1_1_20150802 -rw-r--r-- 1 root root 3072 Aug 2 15:28 thread_1_seq_12.259.886687571 -rw-r--r-- 1 root root 1024 Aug 2 15:28 thread_2_seq_12.276.886687573 [root@sec1 backup]# [root@sec1 backup]# chown -R oracle:oinstall * [root@sec1 backup]# [root@sec1 backup]# ll total 616112 -rw-r--r-- 1 oracle oinstall 17510400 Aug 2 15:28 arch_11qdjhkm_1_1_20150802 -rw-r--r-- 1 oracle oinstall 11666432 Aug 2 15:28 arch_12qdjhkm_1_1_20150802 -rw-r--r-- 1 oracle oinstall 15335424 Aug 2 15:28 ctl_file_14qdjhks_1_1_20150802 -rw-r--r-- 1 oracle oinstall 23183360 Aug 2 15:28 suys_lev0_0pqdjhj7_1_1_20150802 -rw-r--r-- 1 oracle oinstall 8388608 Aug 2 15:28 suys_lev0_0qqdjhj7_1_1_20150802 -rw-r--r-- 1 oracle oinstall 933888 Aug 2 15:28 suys_lev0_0rqdjhj8_1_1_20150802 -rw-r--r-- 1 oracle oinstall 553115648 Aug 2 15:29 suys_lev0_0sqdjhj8_1_1_20150802 -rw-r--r-- 1 oracle oinstall 98304 Aug 2 15:28 suys_spfile_15qdjhkv_1_1_20150802 -rw-r--r-- 1 oracle oinstall 3072 Aug 2 15:28 thread_1_seq_12.259.886687571 -rw-r--r-- 1 oracle oinstall 1024 Aug 2 15:28 thread_2_seq_12.276.886687573 [root@sec1 backup]# |
注意文件的权限问题
2.测试机上创建pfile及相关目录
| *.audit_file_dest='/u01/app/oracle/admin/PROD/adump' *.background_dump_dest='/u01/app/oracle/admin/PROD/bdump' *.compatible='10.2.0.5.0' *.control_files='/u01/app/oracle/oradata/PROD/control01.ctl','/u01/app/oracle/oradata/PROD/control02.ctl','/u01/app/oracle/oradata/PROD/control03.ctl' *.core_dump_dest='/u01/app/oracle/admin/PROD/cdump' *.db_block_size=8192 *.db_domain='' *.db_file_multiblock_read_count=16 *.db_name='PROD' *.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area' *.db_recovery_file_dest_size=2147483648 *.dispatchers='(PROTOCOL=TCP) (SERVICE=PRODXDB)' *.job_queue_processes=10 *.log_archive_format='%t_%s_%r.dbf' *.open_cursors=300 *.pga_aggregate_target=402653184 *.processes=150 *.remote_login_passwordfile='EXCLUSIVE' *.sga_target=1209008128 *.undo_management='AUTO' *.undo_tablespace='UNDOTBS1' *.user_dump_dest='/u01/app/oracle/admin/PROD/udump' |
创建上面的路径，用oracle用户！！！！
| [root@sec1 ~]# su - oracle sec1-> sec1-> mkdir -p /u01/app/oracle/admin/PROD/adump sec1-> sec1-> mkdir -p /u01/app/oracle/admin/PROD/bdump sec1-> sec1-> mkdir -p /u01/app/oracle/admin/PROD/cdump sec1-> sec1-> mkdir -p /u01/app/oracle/admin/PROD/udump sec1-> sec1-> mkdir -p /u01/app/oracle/flash_recovery_area sec1-> sec1-> mkdir -p /u01/app/oracle/oradata/PROD sec1-> |
创建spfile文件，如果不知道路径可以
| sec1-> sqlplus / as sysdba

3.进入rman恢复控制文件
| sec1-> sec1-> rman target /

4.数据库进入mount状态
| sec1-> sec1-> rman target /

如果rman备份集中的归档文件是最新的，可以用下面方法

RMAN> list backup of archivelog all;

注意：如果有最新归档文件没有用rman备份，恢复的时候使用
| recover database using backup controlfile until cancel;
使用这个SQL里面命令前，所有归档备份集(RMAN)要放在归档路径换句话的意思就是要把备份集的归档文件提取出来。
run { allocate channel c1 type disk; set archivelog destination to '/app/bea/expdp'; restore archivelog from sequence 8776 until sequence 8780 thread 1; release channel c1; }
