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
