查看asmcmd有三种方式
1、asmcmd命令行模式
- ASMCMD>cd + //切换到ASM磁盘根路径
- ASMCMD> pwd

- //列出当前ASM客户端的信息
- ASMCMD> lsct

2、不进入asmcmd下，直接执行asmcmd命令方式
- 不进入ASM命令模式下操作，如：
- //查看ASM磁盘占用情况
- [grid@shdb02 ~]$ asmcmd ls -ls
- State Type Rebal Sector Block AU Total_MB Free_MB Req_mir_free_MB Usable_file_MB Offline_disks Voting_files Name
- MOUNTED EXTERN N 512 4096 1048576 5242880 4969060 0 4969060 0 N ARCH/
- MOUNTED EXTERN N 512 4096 1048576 8388608 4291161 0 4291161 0 N DATA/
- MOUNTED EXTERN N 512 4096 1048576 4194304 4148235 0 4148235 0 N FRA/
- MOUNTED NORMAL N 512 4096 1048576 30720 29794 10240 9777 0 Y OCR/
3、在ASM 实例模式下
- //在命令提示符中，设置oracle_sid环境变量为+ASM实例
[grid@shdb02 ~]$ export ORACLE_SID=+ASM2
//在Oracle11g RAC 中以grid用户登入后 , 以sysdba登入也是可以查看asm实例相关的状态， 但是不能做变更， sysasm 角色连接后才可以。- [grid@shdb02 ~]$ sqlplus / as sysasm ##或 sqlplus / as sysdba
