Oracle入门教程：ASM的kfed工具

    来源: 互联网  发布时间：2017-04-23

    本文导语:  ASM常用kfod来获取ASM磁盘组的物理磁盘信息，其用法如下： -bash-3.2$ kfod -help_asm_a/llow_only_raw_disks              KFOD allow only raw devices [_asm_allow_only_raw_disks=TRUE/(FALSE)]_asm_l/ibraries         ASM Libraries[_asm_libraries='lib1',&#...

ASM常用kfod来获取ASM磁盘组的物理磁盘信息，其用法如下：

-bash-3.2$ kfod -help
_asm_a/llow_only_raw_disks              KFOD allow only raw devices [_asm_allow_only_raw_disks=TRUE/(FALSE)]
_asm_l/ibraries         ASM Libraries[_asm_libraries='lib1','lib2',...]
_asms/id                ASM Instance[_asmsid=sid]
a/sm_diskstring         ASM Diskstring [asm_diskstring='discoverystring', 'discoverystring' ...]
d/isks          Disks to discover [disks=raw,asm,all]
g/roup          Group discover [group=controlfile]
n/ohdr          KFOD header suppression [nohdr=TRUE/(FALSE)]
o/p             KFOD options type [OP=DISKS/GROUPS/ALL]
p/file          ASM parameter file [pfile='parameterfile']
s/tatus         Include disk header status [status=TRUE/(FALSE)]
v/erbose                KFOD verbose errors [verbose=TRUE/(FALSE)]










获取asm磁盘的情况：

-bash-3.2$ kfod disk=all
--------------------------------------------------------------------------------
 Disk          Size Path      
================================================================================
   1:       8032 Mb /dev/raw/raw3
--------------------------------------------------------------------------------
Oracle_SID ORACLE_HOME                                                          
================================================================================
     +ASM1 /opt/rac/database      
而kfed工具支持对于ASM信息的READ/WRITE/MERGE/NEW/ FORM/FIND/STRUCT等操作，但是需要手工编译：









-bash-3.2$ cd $ORACLE_HOME/rdbms/lib 

-bash-3.2$ make -f ins_rdbms.mk ikfed
