oracle11g rac asm存储数据迁移

OS：rh6.4

ORACLE 11g RAC ASM

OCR和VOTING DISK在crs磁盘组，控制文件、数据文件、参数文件在DATA组。

1、备份数据库

RUN {
ALLOCATE CHANNEL ch00 DEVICE TYPE disk;
ALLOCATE CHANNEL ch01 DEVICE TYPE disk;
backup database filesperset 5 format '/u01/backup/bk_%d_%T%s_%p' ;
backup current controlfile format '/u01/backup/ctl_%d_%T_%s';
RELEASE CHANNEL ch00;
RELEASE CHANNEL ch01;
}

2、备份参数文件

3、停止监听

4、查看字符集、数据文件、用户等
