1.1 获取磁盘组管理信息
1.1.1 查看磁盘路径
SQL> selectname, path, group_number from v$asm_disk_stat ；
1.1.2 查看磁盘组信息
SQL> selectstate,name,type,total_mb, free_mb from v$asm_diskgroup_stat ;
磁盘组状态为Mounted说明磁盘组状态正常;
磁盘组的total_mb,free_mb为非0说明可以读取磁盘信息,获取磁盘大小。
1.1.3 查看磁盘组操作
select * fromv$asm_operation
OPERA STATPOWER ACTUAL SOFAR EST_WORK EST_RATE EST_MINUTES
----- -------------- ---------- ---------- ---------- ---------- -----------
1 REBAL WAIT11 0 0 0 0 0
1 DSCV WAIT 110 0 0 0 0
(timepasses…………..)

----------------- ---- ---------- ---------- ---------- ---------- ----------
1 REBAL REAP11 2 25 219 485 0
1.1.4 查看磁盘组属性
查询V$ASM_ATTRIBUTE视图查看磁盘组属性
SQL> SELECT dg.name AS diskgroup,SUBSTR(a.name,1,18) AS name,
SUBSTR(a.value,1,24) AS value, read_only FROM V$ASM_DISKGROUP_STAT dg,
V$ASM_ATTRIBUTE a WHERE dg.name = 'DATA'
AND dg.group_number = a.group_number;
1.1.5 查看磁盘组兼容属性
SQL> SELECT name,COMPATIBILITY,DATABASE_COMPATIBILITY FROM V$ASM_DISKGROUP_STAT;
1.1.6 查看磁盘状态
SQL> SELECT SUBSTR(d.name,1,16) AS asmdisk,d.mount_status,HEADER_STATUS, d.state,
dg.name AS diskgroup FROM V$ASM_DISKGROUP_STAT dg, V$ASM_DISK_STAT d
WHERE dg.group_number = d.group_number;
1.1.7 查看磁盘客户端信息
SQL> SELECT dg.name AS diskgroup,SUBSTR(c.instance_name,1,12) AS instance,
SUBSTR(c.db_name,1,12) AS dbname,SUBSTR(c.SOFTWARE_VERSION,1,12) AS software,
SUBSTR(c.COMPATIBLE_VERSION,1,12) AS compatible
FROM V$ASM_DISKGROUP_STAT dg, V$ASM_CLIENT c
WHERE dg.group_number = c.group_number;
1.1.8 查看磁盘访问控制用户信息
SQL> SELECT dg.name AS diskgroup, u.group_number,u.user_number, u.os_id, u.os_name
FROM V$ASM_DISKGROUP_STAT dg, V$ASM_USER u
WHERE dg.group_number = u.group_number AND dg.name ='DATA';
1.1.9 查看磁盘访问控制组信息
SQL> SELECT dg.name AS diskgroup, ug.group_number,ug.owner_number, u.os_name,
ug.usergroup_number, ug.name FROM V$ASM_DISKGROUP_STAT dg, V$ASM_USER u, V$ASM_USERGROUP ug
WHERE dg.group_number = ug.group_number AND dg.name ='DATA'
AND ug.owner_number = u.user_number;
1.1.10 查看智能数据分布信息
SQL> SELECT dg.name AS diskgroup, f.file_number, f.primary_region,f.mirror_region, f.hot_reads,f.hot_writes, f.cold_reads, f.cold_writes
FROM V$ASM_DISKGROUP_STAT dg, V$ASM_FILE f
WHERE dg.group_number = f.group_number and dg.name ='DATA';
