把文件系统的数据文件迁移到ASM存储

RAC环境,使用的是ASM作存储。
近日在给用户做数据库维护的过程中,发现有一部分数据文件存放在文件系统中,这是不正常的。导致另一台服务器上跑着的实例就不正常了。
 于是需要把文件系统上的数据文件迁移到ASM存储上。

如何修改ASM的sys密码

如何将ASM中的数据文件复制到操作系统中

Oracle 11g从入门到精通 PDF+光盘源代码

RHEL6 ASM方式安装Oracle 11g R2

Oracle 10g 手工创建ASM数据库

下面模拟该场景
 在rac1的节点上操作

未添加数据文件前数据文件的情况
 SQL> select name from v$datafile;

4 rows selected.

SQL> alter tablespace users add datafile 'user01.dbf' size 10m;

Tablespace altered.

SQL> select file_name from dba_data_files;

FILE_NAME

 /u01/oracle/product/11.2.0/db_1/dbs/user01.dbf
 
5 rows selected.

我们过一段时间,观测其他节点。
 我们使用sqlplus 登陆会报错误。
 使用conn sys/password@devdb2 as sysdba,报以下错误:
 ERROR:
 ORA-01075: you are currently logged on
 2、以normal 身份的用户连接(conn username/password@devdb2),报以下错误:
 ERROR:
 ORA-00604: 递归 SQL 级别 2 出现错误
 ORA-01157: 无法标识/锁定数据文件 5 - 请参阅 DBWR 跟踪文件
 ORA-01110: 数据文件 5: '/u01/oracle/product/11.2.0/db_1/dbs/user01.dbf'
 ORA-00604: 递归 SQL 级别 2 出现错误

 ORA-01110: 数据文件 5: '/u01/oracle/product/11.2.0/db_1/dbs/user01.dbf'


下面我采用rman 的方式,把/u01/oracle/product/11.2.0/db_1/dbs/user01.dbf数据文件
 迁移到ASM存储上。
 把数据库启动到mount状态下
 SQL> startup mount
 ORACLE instance started.

 使用rman链接数据库
