RMAN 迁移ASM到异机文件系统实战

环境说明：

源库：192.168.0.10

目标库：192.168.0.11

 

源库备份：

RMAN> run {

2> allocate channel c1 device type disk;

3> allocate channel c2 device type disk;

4> backup database format '/home/Oracle/full_database%U' include current controlfile;

5> sql 'alter system archive log current'; 

6> backup archivelog all format '/home/oracle/archivelog_%U';

7> crosscheck backup;

8> delete noprompt obsolete;

9> release channel c1;

10> release channel c2;

11> }

 

复制备份集到备库：

scp /home/oracle/full* oracle@192.168.0.11:/home/oracle/target_bk/

scp /home/oracle/archive* oracle@192.168.0.11:/home/oracle/target_bk/

[oracle@targetdb target_bk]$ ls

archivelog_0rnu4jbf_1_1  full_database0nnu4ja0_1_1  full_database0pnu4jb4_1_1

archivelog_0snu4jbf_1_1  full_database0onu4ja0_1_1  full_database0qnu4jb5_1_1

 

目标库操作

[oracle@targetdb sourcedb]$ mkdir {a,b,c,u}dump

[oracle@targetdb sourcedb]$ ls

adump  bdump  cdump  udump

 

[oracle@targetdb oradata]$ mkdir sourcedb

[oracle@targetdb oradata]$ ls

sourcedb 

[oracle@targetdb oradata]$ cd sourcedb/

[oracle@targetdb sourcedb]$ mkdir arch

[oracle@targetdb sourcedb]$ ls

arch

 

开始恢复：

因为还没有参数文件，先使用rman 无参数启动

export ORACLE_SID=sourcedb

RMAN> startup nomount;   

 

startup failed: ORA-01078: failure in processing system parameters
