Quick snippet for corente setup, the Corente gateway server is supposed to be running, and both files oc_config_corente-tunnel and corente-tunnel-args, properly configured, are supposed to have been staged on the VMs, under the OPC account:

sudo cp oc-config-corente-tunnel /usr/bin
sudo chmod 550 /usr/bin/oc-config-corente-tunnel 
sudo yum install bind-utils
sudo mkdir /var/log/opc-compute
sudo chmod +x /etc/rc.d/rc.local
sudo vi /etc/rc.d/rc.local

add the following line to the rc.local file

bash /usr/bin/oc-config-corente-tunnel

Implement corente by restarting the cloud service, rebooting the VM, or by running

sudo bash /usr/bin/oc-config-corente-tunnel

Setting up the environment context

export IAAS_HOME=/opt/oracle/iaas/cli
export JAVA_HOME=/usr/java/jdk1.7.0_131

To create and mount a logical volume on a new block storage volume, process as below, typically for /dev/xvdc

pvcreate /dev/xvdc1
vgcreate vg_oracle /dev/xvdc1
lvcreate -l 20 -n lv_oracle vg_oracle
lvextend --extents +100%FREE /dev/vg_oracle/lv_oracle
e2fsck -f /dev/vg_oracle/lv_oracle
mkfs.ext4 /dev/vg_oracle/lv_oracle -L oracle
mkdir -p /u01/app/oracle
mount /dev/mapper/vg_oracle-lv_oracle /u01
chown oracle:oinstall /u01/app/oracle

To extend the root logical volume:

pvcreate /dev/xvdc1
vgextend vg_main /dev/xvdc1 
lvextend --extents +100%FREE /dev/vg_main/lv_root
resize2fs /dev/vg_main/lv_root
