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
