Step2. Configure Oracle ASM

Load / initiate Oracle ASM

init 0

Add 25 GB HDD to virtual machine which we will use to create 3 partitions of 5,10,10 GB each for our ASM disks.

Open Virtual machine >> Settings >> Storage >> Controller: SATA >> Create new disk

Click on OK & Start the VM Machine.

Start virtual machine and login as root user to format the newly added disk

Step3. Create separate ASM Disk for each partition

To check asm disks

Step4. Install Grid Software

Put the content under vi text editor in bash profile & save it.

1	`[grid@dg11 ~]$ vi .bash_profile`

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
