原机： OS:Linux x86 64-bit IP:192.168.59.156 oracle：10.2.0.1.0 归档模式

异机： OS:Linux x86 64-bit IP:192.168.59.10 oracle：11.2.0.3.0 归档模式

目的：利用原机的rman备份集将原库恢复到异机。

一、全备份原数据库并拷贝到异机

备份脚本如下：

[oracle@redhat4 ~]$ mkdir -p /home/oracle/oracle_bk/orcl/

run{

allocate channel c1 type disk;

allocate channel c2 type disk;

backup database filesperset 4 format '/home/oracle/oracle_bk/orcl/full_%n_%T_%t_%s_%p.bak';

backup spfile format='/home/oracle/oracle_bk/orcl/spfile_%n_%U_%T.bak';

sql 'alter system archive log current';

backup archivelog all format '/home/oracle/oracle_bk/orcl/arch_%d_%T_%s_%p.bak' delete input;

backup current controlfile format '/home/oracle/oracle_bk/orcl/ctl_%d_%T_%s_%p.bak';

release channel c1;

release channel c2;

}

[oracle@redhat4 ~]$ sqlplus / as sysdba

SQL*Plus: Release 10.2.0.1.0 - Production on 星期四 4月 9 16:27:13 2015

连接到:

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production

With the Partitioning, OLAP and Data Mining options

SQL> create pfile from spfile;

File created.

[oracle@redhat4 ~]$ rman target /

恢复管理器: Release 10.2.0.1.0 - Production on 星期四 4月 9 16:22:07 2015

连接到目标数据库: JIAGULUN (DBID=2694191837)

RMAN> list backupset;

使用目标数据库控制文件替代恢复目录

RMAN> run{

2> allocate channel c1 type disk;

3> allocate channel c2 type disk;

4> backup database filesperset 4 format '/home/oracle/oracle_bk/orcl/full_%n_%T_%t_%s_%p.bak';

5> backup spfile format='/home/oracle/oracle_bk/orcl/spfile_%n_%U_%T.bak';

6> sql 'alter system archive log current';

7> backup archivelog all format '/home/oracle/oracle_bk/orcl/arch_%d_%T_%s_%p.bak' delete input;

8> backup current controlfile format '/home/oracle/oracle_bk/orcl/ctl_%d_%T_%s_%p.bak';

9> release channel c1;

10> release channel c2;

二、在异机的操作 1、恢复spfile

这里不采用rman恢复了，因为要实验异机不同路径的恢复，所以直接修改pfile文件吧。

[oracle@testdb orcl]$ cd /tmp/orcl

[oracle@testdb orcl]$ cp initjiagulun.ora $ORACLE_HOME/dbs/

[oracle@testdb orcl]$ vi $ORACLE_HOME/dbs/initjiagulun.ora

修改pfile文件之后：

[oracle@testdb orcl]$ more $ORACLE_HOME/dbs/initjiagulun.ora

*.audit_file_dest='/u01/app/oracle/admin/jiagulun/adump'

*.compatible='10.2.0.1.0'

*.control_files='/u01/app/oracle/oradata/jiagulun/control01.ctl','/u01/app/oracle/oradata/jiagulun/control02.ctl'

*.db_block_size=8192

*.db_create_file_dest='/u01/app/oracle/oradata'

*.db_domain=''

*.db_file_multiblock_read_count=16

*.db_name='jiagulun'

*.db_recovery_file_dest='/u01/app/oracle/flash_recovery_area'

*.db_recovery_file_dest_size=2147483648

*.dispatchers='(PROTOCOL=TCP) (SERVICE=jiagulunXDB)'

*.job_queue_processes=10

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile='EXCLUSIVE'

*.sessions=170

*.memory_target=500572800

*.undo_management='AUTO'

*.undo_tablespace='UNDOTBS1'

[oracle@testdb orcl]$

创建相关路径：

[oracle@testdb orcl]$ mkdir -p /u01/app/oracle/admin/jiagulun/adump

[oracle@testdb orcl]$ mkdir -p /u01/app/oracle/oradata/jiagulun/

[oracle@testdb orcl]$

---创建原库的相关路径

[oracle@testdb dbs]$ mkdir -p /u01/app/oracle/oradata/JIAGULUN/datafile/

[oracle@testdb dbs]$ mkdir -p /u01/app/oracle/oradata/JIAGULUN/onlinelog/

2、恢复控制文件
