ODI on Compute Cloud Service: Step by Step Installation


We have seen in Connect ODI to Oracle Database Cloud Service (DBCS) how to connect ODI on premise to DBCS.
But it is also possible to deploy ODI in the Cloud – either on the PAAS (on JCS) or the IAAS (on Compute Cloud Service).
In cases where a JEE ODI Agent is not needed, deploying ODI on Compute is a good alternative.

We are describing here step by step instructions to deploy ODI in this environment.


    • We already have a Database Cloud Service Instance up and running (please refer to this Oracle By Example tutorial for detailed steps: Creating a Database Cloud Service Instance).
    • We also have our Private and Public SSH Keys stored safely.
    • Of course we have an access to Compute Cloud Service Console.

Let’s connect to the Compute Cloud Services console

Storage Volumes

Based on Best Practices for Using Oracle Compute Cloud Service we are going to create 2 distinct Storage Volumes.

  • One Bootable Storage, which will contain the OS image. We will select an Oracle Linux Image, version 6.6. To see the detail of Oracle Linux Images please refer to About Oracle-Provided Linux Images
  • One Software Storage (to store ODI install and other software if needed).

In the Compute Cloud Services console, we go on the Storage tab and click on Create Storage Volume:



  • For the Bootable Storage:
      • We select the Oracle Linux Boot Image: OL‐6.6‐20GB‐x11RD

      • For the Software Storage:
          • We select Boot Image: none
          • Size: 100 Gb

Compute Instance

We can now create the Compute Instance:

First, we need to select the image we want to deploy on our Cloud Instance.
As explained above while creating the storage volume, we want to install an Oracle Linux 6.6, so we are going to select OL-6.6-20GB-x11-RD

We will now click on each “tab” of the creation wizard.

On Shape, we select oc4

In the Instance tab, we enter the Name, Description, DNS Hostname prefix and select our SSH key.

We click on Storage and on Attach Existing Volume

ODI on Compute Linux08

We select the volumes we have created: Linux_Boot as “Boot Drive” and Linux_Soft. To keep the instance clean, we delete the default image (in our example CF_LINUX_boot)

We are almost there – we click on Review and check we have attached the SSH key and the Storage – then we can click on Create

ODI on Compute Linux09

We can go in Orchestrations to see the instance is starting

ODI on Compute Linux10

We go back in “Instances” … we wait for a while (few minutes) then we see our instance created and running.

ODI on Compute Linux11

We note the IP address; it will be used in next step

Connection through SSH

In order to access to our new Compute Instance, we can log in using SSH as opc user.

Refer to Accessing an Oracle Linux Instance Using SSH for more details.

From Windows, we create a new Putty Session to connect to the newly created Compute Service. We enter:

  • Host Name= the above IP
  • Port = 22

ODI on Compute Linux12

Then we enter the Private SSH Key in Connection/SSH/Auth

We go back to Sessions and Save.

First time we open the connection we get a security alert:

ODI on Compute Linux13

Click yes – then we are in!!

ODI on Compute Linux14

Storage Volume Handling

While we have created the Compute Instance the Boot Storage is automatically mounted.
We need to mount the additional Storage Volume we have created (Linux_Soft) and attach a folder to it. We will install ODI in that folder.
Refer to Mounting a Storage Volume on a Linux Instance for more details.

First, let’s create a new folder that we will use to store all downloads and ODI installation.

sudo mkdir /u01
sudo chmod 755 /u01

As the Storage Volume we want to mount, Linux_Soft, is on disk 3, the device name will be /dev/xvdd.

We can check the devices on the instance:

ls /dev/xvd*

We create the file system on xvdd

sudo mkfs -t ext4 /dev/xvdd

And finally mount it as u01

sudo mount /dev/xvdd /u01

We create a folder to store downloaded software

sudo mkdir /u01/backup
sudo chmod 755 /u01/backup

VNC Server set-up

As user opc, we edit sshd_config:

vi /etc/ssh/sshd_config

To forward the application display to our local Windows machine, we change all occurrences of X11Forwarding to yes:

X11Forwarding yes

We restart sshd by running the following command:

sudo /etc/init.d/sshd restart

We run the following command to prevent the Window Manager from displaying a lock screen:

gconftool-2 -s -t bool /apps/gnome-screensaver/lock_enabled false

To ensure that the $TMP and $TMPDIR directories are accessible and have write permissions before starting the VNC server, we edit the .bashrc file and set the following values:

vi ~opc/.bashrc

export TMPDIR=/tmp

export TEMPDIR=/tmp

export TMP=/tmp

export TEMP=/tmp

We Rerun the profile (notice the leading period and space):

[OS]$ . ~opc/.bashrc

Observe the current temp environment variables to make sure they all point to the new /tmp. At a command prompt, re-enter this command:

env | grep tmp .

We start VNC server with the following command:

vncserver :1 -depth 16 -alwaysshared -geometry 1200×750 -s off

We stop the SSH connection and update it to add a Tunnel to connect to our Compute Cloud Service through SSH tunneling. We click on Connection/SSH/Tunnels and add the following tunnel:

Session/save and … we open our updated connection.

Once we are connected, we can now launch our favorite VNC client to connect to our VNC Server:

ODI on Compute Linux18

Now we are ready to download and install ODI!

JDK and ODI Downloads

First thing to do is to download the required JDK certified with ODI.

As our goal is to install ODI we can see in the Certification Matrix that the minimum JDK version is 1.8.0_77. At the date of writing (Sept 2016), the best selection is jdk-8u101-linux-x64.rpm

At this point ODI is available for download at http://www.oracle.com/technetwork/middleware/data-integrator/downloads/index.html

If you have difficulties connecting to the Oracle web site from the VNC Server, a workaround is to force the DNS to another value than the default one. (cf. https://community.oracle.com/message/13903890#13903890).

JDK Install

We move the downloaded files to /u01/backup

mv /home/opc/Downloads/* /u01/backup

We go in /u01/backup and install the package using

sudo rpm -ivh jdk-8u101-linux-x64.rpm

We check the JDK is installed:

java -version

java version “1.8.0_101”

ODI Install

Now we are ready to install ODI – refer to Installation Guide for Oracle Data Integrator for details

java -jar fmw_12.

ODI on Compute Linux19

Oracle_Home must be under u01 directory to have enough space and take benefit of the Linux_Soft Storage Volume we have mounted.

ODI on Compute Linux20

Repository Creation

Refer to Creating the Master and Work Repository Schemas for details on how to launch RCU.
In this case we are using a DBCS Instance sharing the same Domain as the Compute Instance.

ODI on Compute Linux21


We have seen the steps to install ODI on a Compute Instance – which is as easy as installing ODI on any Linux Server. We will detail the connections between the ODI Cloud instance and other DBCS in a next article.
