oracle数据库文件系统迁移到ASM

查看ASM磁盘组

SQL> select name,state from  v$asm_diskgroup;

登陆RMAN执行镜像全备到ASM磁盘组

修改文件创建默认位置和控制文件位置

SQL> alter system set control_files='+data' scope=spfile;

System altered.

SQL> alter system set db_create_file_dest='+data' scope=spfile;

System altered.

重启

SQL> shutdown immediate
SQL> startup

迁移控制文件

RMAN> startup nomount

RMAN> restore controlfile from '/u01/app/oracle/oradata/PROD1/control02.ctl';

迁移数据文件

RMAN> alter database mount;

RMAN> switch database to copy;
RMAN> recover database;     #一致性备份不需要）
RMAN> alter database open;

迁移日志文件
创建新文件，删除老文件。(日志组处于INACTIVE状态才可以删除）

SQL> select group#,status from v$log;

强制切换日志组改变日志组状态

SQL> alter system switch logfile;

删除老的日志组(删一个，加一个)

SQL> alter database drop logfile group 3;
Database altered.
SQL> alter database drop logfile group 1;
Database altered.
SQL> alter database drop logfile group 2;
Database altered.

增加日志组到ASM

SQL> alter database add logfile group 3 '+data' size 50m;
Database altered.
SQL> alter database add logfile group 1 '+data' size 50m;
Database altered.
SQL> alter database add logfile group 2 '+data' size 50m;
Database altered.

迁移初始化文件

SQL> create pfile from spfile;
File created.
SQL> create spfile='+data' from pfile;
File created.

vi $ORACLE_HOME/dbs/initPROD1.ora
spfile='+data/db_unknown/parameterfile/SPFILE.263.905991571'

mv spfilePROD1.ora spfilePROD1.ora.bak

迁移temp文件

SQL> select name from v$tempfile;
SQL> alter tablespace temp add tempfile '+data'；
SQL> alter tablespace temp drop tempfile '/u01/app/oracle/oradata/PROD1/temp01.dbf';
SQL> select name from v$tempfile;

查看迁移的文件

SQL> select name from v$datafile union select name from v$tempfile union select name from v$controlfile union select member from v$logfile;
