ASM磁盤組信息查看常用命令
1.1 獲取磁盤組管理信息
1.1.1 查看磁盤路徑
SQL> selectname, path, group_number from v$asm_disk_stat ；
1.1.2 查看磁盤組信息
SQL> selectstate,name,type,total_mb, free_mb from v$asm_diskgroup_stat ;
磁盤組狀態為Mounted說明磁盤組狀態正常;
磁盤組的total_mb,free_mb為非0說明可以讀取磁盤信息,獲取磁盤大小。
1.1.3 查看磁盤組操作
select * fromv$asm_operation
OPERA STATPOWER ACTUAL SOFAR EST_WORK EST_RATE EST_MINUTES
----- -------------- ---------- ---------- ---------- ---------- -----------
1 REBAL WAIT11 0 0 0 0 0
1 DSCV WAIT 110 0 0 0 0
(timepasses…………..)
OPERA STATPOWER ACTUAL SOFAR EST_WORK EST_RATE EST_MINUTES
----------------- ---- ---------- ---------- ---------- ---------- ----------
1 REBAL REAP11 2 25 219 485 0
1.1.4 查看磁盤組屬性
查詢V$ASM_ATTRIBUTE視圖查看磁盤組屬性
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 查看磁盤組兼容屬性
1.1.6 查看磁盤狀態
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 查看磁盤客戶端信息
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 查看磁盤訪問控制用戶信息
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 查看磁盤訪問控制組信息
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$ASM_USERGROUP ug
WHERE dg.group_number = ug.group_number AND dg.name =‘DATA‘
AND ug.owner_number = u.user_number;
1.1.10 查看智能數據分布信息
SQL> SELECT dg.name AS diskgroup,
f.file_number, f.primary_region,f.mirror_region,
f.hot_reads,f.hot_writes, f.cold_reads, f.cold_writes
FROM V$ASM_DISKGROUP_STAT dg, V$ASM_FILE f
WHERE dg.group_number = f.group_number and dg.name =‘DATA‘;
