Oracle RMAN Migrate from Single none-ASM to Single ASM

环境: Linux 5.6 x86-64 + ASM(single instance) + Oracle 11.2.0.3(single instance)

--迁移前控制文件，数据文件(临时文件)，日志文件，参数文件。

步骤：

+ 控制文件，数据文件，临时文件迁移。

+ 在线日志迁移

+ 参数文件迁移

--数据库迁移之RMAN从文件系统至ASM

SQL> alter system set db_create_file_dest='+DATA' scope=both;

RMAN> restore controlfile to '+DATA' from '/u01/app/oracle/oradata/hdb11g/control01.ctl';

SQL> alter system set control_files='+DATA/HDB11G/CONTROLFILE/current.256.824626491' scope=spfile;

SQL> shutdown immediate;

SQL> startup mount;

RMAN> backup full database tag 'FULL' format='/u01/FULL_%d_%T_%s';

RMAN> backup current controlfile tag 'CTRL' format '/u01/CTRL_%d_%T_%s';

RMAN> run{

SET NEWNAME FOR DATABASE TO '+DATA';

SET NEWNAME FOR TEMPFILE 1 TO '+DATA';

RESTORE DATABASE;

SWITCH DATAFILE ALL;

SWITCH TEMPFILE ALL;

}

SQL> alter database open;

此时，控制文件，数据文件已经迁到了ASM上了，可以直接open数据库。

如果需要将redo log也放在ASM中，则需要重建redo log，在open状态下可以进行如下操作。

SQL> alter system set db_create_online_log_dest_1='+DATA' scope=both;

SQL> select * from v$log;

SQL> select * from v$logfile;

删除inactive状态的日志组，重建日志。

SQL> alter database drop logfile group 1;

SQL> alter database add logfile group 1 size 50M;

SQL> alter database drop logfile group 2;

SQL> alter database add logfile size 50M;

SQL> alter system switch logfile;

SQL> alter system checkpoint;

SQL> alter database drop logfile group 3;

SQL> alter database add logfile ('+DATA','+RECOVERY') size 50M;

如果需要将spfile也放在ASM中，如下步骤。

SQL> create pfile from spfile;

SQL> shutdown immediate;

SQL> startup nomount pfile='?/dbs/inithdb11g.ora';

SQL> create spfile='+DATA' from pfile;

ora11gr2.sannet.net | hdb11g | /u01/app/oracle/product/11.2.0.3.0/db_1/dbs > rm -rf spfilehdb11g.ora

ora11gr2.sannet.net | hdb11g | /u01/app/oracle/product/11.2.0.3.0/db_1/dbs > vi inithdb11g.ora

spfile='+DATA/HDB11G/PARAMETERFILE/spfile.276.824633307'

SQL> shutdown immediate;

SQL> startup;

SQL> show parameter pfile;
