一些 Oracle ASM 常用命令整理。
01, 查看磁盘路径
select name,path,group_number from v$asm_disk_stat;
02, 查看磁盘组信息
select state,name,type,total_mb, free_mb from v$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。
03, 查看磁盘组操作
select * from v$asm_operation;
04, 查看磁盘组属性
SELECT dg.name AS diskgroup,SUBSTR(a.name,1,18) AS name,SUBSTR(a.value,1,24) AS value, read_only FROM v$ASM_DISKGROUP_STAT dg,
v$ASM_ATTRIBUTE a WHERE dg.name = ‘DATA’ AND dg.group_number = a.group_number;
05, 查看磁盘组的兼容属性
SELECT name,COMPATIBILITY,DATABASE_COMPATIBILITY FROM V$ASM_DISKGROUP_STAT;
06, 查看磁盘状态
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;
07, 查看磁盘客户端信息
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;
08, 查看磁盘访问控制用户信息
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’;
09, 查看磁盘访问控制组信息
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$ASM_USERGROUP ug WHERE dg.group_number = ug.group_number AND dg.name =’DATA’ AND ug.owner_number = u.user_number;
10, 查看智能数据分布信息
SELECT dg.name AS diskgroup, f.file_number, f.primary_region,f.mirror_region,f.hot_reads,f.hot_writes, f.cold_reads, f.cold_writes FROM V$ASM_DISKGROUP_STAT dg, V$ASM_FILE f WHERE dg.group_number = f.group_number and dg.name =’DATA’;
