iDIH DB Installation

5.10 iDIH DB Installation

Log in to the host machine as a root user where you need to install the IDIH DB.
Delete existing VM.
1. Identify the VM by its domain:
```
# virsh list –all
```
2. Remove the VM.
```
# virsh destroy <VM Name>
# virsh undefine <VM Name>
```
3. Remove the VM qcow2 file by deleting the file from path /home/repository
4. Refresh storage pool dedicated for DSR.
```
# virsh pool - -list
# virsh pool-refresh <pool_name>
```
Create a VM on the host machine.
1. Copy the iDIH Oracle ova’s zip file to path /home/repository.
2. Convert the resulting .vmdk file to a qcow2.
```
qemu-img convert -f vmdk -O qcow2 ORA-XX_XX_XX.vmdk ORA-XX_XX_XX.qcow2
```
3. Refresh storage pool dedicated for DSR.
```
# virsh pool - -list
# virsh pool-refresh <pool_name>
```
4. Resize ORA (database) ova image on KVM.
```
# qemu-img info ORA-XX_XX_XX.qcow2
```
  The output of above command would reflect “virtual size” as 64 GB.
```
# qemu-img resize ORA-82_40_0.qcow2 +56G
# qemu-img info ORA-82_40_0.qcow2
```
  The output of above command would reflect “virtual size” as 120 GB.
```
# chown qemu:qemu ORA-82_40_0.qcow2
```
5. Create additional disk of 100GB required for Oracle database as mentioned in the cloud installation doc Create SDB on KVM on KVM.
6. Create a VM with following command:
```
virt-install --name=<VM-NAME> --ram=8192 --vcpus=4 --cpuset=32-35 --disk path=/var/lib/libvirt/images/ORA-82_40_0.qcow2,format=qcow2,bus=<scsi/virtio> --network bridge:<XMI-BRIDGE>,model=virtio --network bridge:<INT-BRIDGE>,model=virtio --graphics none --autostart --watchdog i6300esb,action=reset --import
```
7. Run virsh list --all on KVM to verify whether VM has been created.
8. Shut down Oracle VM.
```
virsh shutdown <VM-NAME>
```
9. Attach the additional 100GB disk created in unresolvable-reference.html#GUID-180432FE-6669-418E-A20F-3C7C8A945153.
10. Follow the steps in Run Post Installation Scripts on iDIH VMs and Configure DSR Reference Data Synchronization for iDIH for Oracle VM configuration and post installation.
