Using Oracle10g Release 2 KFED tools to view ASM DISK structure

« How to Use Oracle10g release 2 ASM | Blog首页 | How to compile Oracle10g / Oracle11g BBED tools »

Oracle10g内含了一个ASM工具kfed,可以用来查看ASM磁盘的物理结构，不过该工具需要我们自己编译一下才能使用。

编译方法很简单:
[root@danaly ~]# su - oracle
[oracle@danaly ~]$ cd $ORACLE_HOME/rdbms/lib
[oracle@danaly lib]$ make -f ins_rdbms.mk ikfed

我们简单看一下便以过程:

[root@danaly ~]# su - oracle
[oracle@danaly ~]$ cd $ORACLE_HOME/rdbms/lib

[oracle@danaly lib]$ make -f ins_rdbms.mk ikfed

Linking KFED utility (kfed)
rm -f /opt/oracle/product/10.2.0/rdbms/lib/kfed
gcc -o /opt/oracle/product/10.2.0/rdbms/lib/kfed ...
mv -f /opt/oracle/product/10.2.0/bin/kfed /opt/oracle/product/10.2.0/bin/kfedO
mv: cannot stat `/opt/oracle/product/10.2.0/bin/kfed': No such file or directory
make: [ikfed] Error 1 (ignored)
mv /opt/oracle/product/10.2.0/rdbms/lib/kfed /opt/oracle/product/10.2.0/bin/kfed
chmod 751 /opt/oracle/product/10.2.0/bin/kfed
[oracle@danaly lib]$ which kfed
~/product/10.2.0/bin/kfed

kfed有很多用途，我们可以用-h参数看一下相关帮助:

[oracle@danaly lib]$ kfed -h
as/mlib         ASM Library [asmlib='lib']
aun/um          AU number to examine or update [AUNUM=number]
aus/z           Allocation Unit size in bytes [AUSZ=number]
blkn/um         Block number to examine or update [BLKNUM=number]
blks/z          Metadata block size in bytes [BLKSZ=number]
ch/ksum         Update checksum before each write [CHKSUM=YES/NO]
cn/t            Count of AUs to process [CNT=number]
d/ev            ASM device to examine or update [DEV=string]
o/p             KFED operation type [OP=READ/WRITE/MERGE/NEW/FORM/FIND/STRUCT]
p/rovnm         Name for provisioning purposes [PROVNM=string]
te/xt           File name for translated block text [TEXT=string]
ty/pe           ASM metadata block type number [TYPE=number]

我们来读取一下ASM磁盘头看一下ASM磁盘的相关信息:
