Hi



I am having standalone (NON-RAC) box with Linux AS3 (Kernel Ver.
2.4.21.4) and oracle 10G installed on it. It is having one database as
ORCL. Now i wants to configure ASM on it. For that I did the following
activities.



mkdir -p /u03

mkdir -p /u03/asmdisks



dd if=/dev/zero of=/u03/asmdisks/disk0 bs=1024k number=100

dd if=/dev/zero of=/u03/asmdisks/disk1 bs=1024k number=100

dd if=/dev/zero of=/u03/asmdisks/disk2 bs=1024k number=100

dd if=/dev/zero of=/u03/asmdisks/disk3 bs=1024k number=100



chown -R oracle:oinstall /u03

chmod -R 777 /u03



Then I chose to create the database through DBCA. Where I gave database
Sid as ASM and selected AUTOMATIC STORAGE MANAGEMENT for the storage. In
the parameter of asm instance I set the parameter asm_diskstring as
*/u03/asmdisks/*'



ASM Instance gets started with this as when i do "ps -aux | grep +asm"
then it shows the ASM processes.



Now when i create the diskgroup as DGROUP1 with normal redundancy, I am
not able to see member disks which i have defined in ASM instance
parameter "asm_diskstring".



Is there any need to install ASM libraries?



Can I simulate the test environment using OS IO's (Without using ASM
Libraries).



Kindly Help.



Regards

Bally
