Getting Started with Oracle Cloud Marketplace

1.1 Prerequisites

Make sure you have the following prerequisites before using Oracle Data Integrator on Oracle Cloud Marketplace:

Oracle Cloud Account
Have access to assigned Oracle Cloud Tenant
Compute node resources within Oracle Cloud Tenant

Go through the following prerequisites carefully before creating the ODI instance:

Refer to Creating Dynamic Group Polices for compartment, before provisioning ODI and ADB Instances.
Read thoroughly the password policies provided in the Stack UI and create passwords accordingly during provisioning.
Wait till the completion of ODI instance creation, check for its status and then proceed working on it.
For more information, refer to the usage instructions in Launching Your Oracle Data Integrator Instance.

Supported Browsers

Oracle Cloud Infrastructure supports the latest desktop versions of Google Chrome, Microsoft Edge, Internet Explorer 11, Safari, Firefox, and Firefox ESR. Note that mobile browsers as well as private browsing mode is not supported for Firefox, Internet Explorer, or Edge.

Creating an SSH/RSA Key

To work with the Oracle Cloud Infrastructure once the Oracle Data Integrator Compute Node is built, you have to provide a SSH Public Key to allow you to login to the node.

In order to build your SSH keys, perform the following steps:

In a terminal window, generate the SSH key using the following command:
```
$ ssh-keygen Generating public/private rsa key pair.
```
Enter the path to store this file. By default, this gets saved in your home directory under a hidden folder called .ssh. Change this default location, if required.
```
Enter file in which to save the key (/Users/johndoe/.ssh/id_rsa): <Return>
```

Enter a passphrase using your key.

Enter passphrase (empty for no passphrase): <passphrase>

Re-enter the passphrase to confirm it.
```
Enter same passphrase again: <passphrase>
```
Check the results.
The key fingerprint (a colon separated series of two digit hexadecimal values) is displayed. Check if the path to the key is correct. In the above example, the path is /Users/johndoe/.ssh/id_rsa.pub. You have now created a public and private key pair.

Creating Dynamic Group and Policies

During ODI Instance provisioning, data servers for all accessible Autonomous Databases (ADB) are automatically created, as long as the dynamic group and policies are created before deploying ODI on Marketplace and are set as mentioned below. Dynamic Group and Policies are required when using the ODI Repository on an Autonomous Database.

Create a dynamic group to include matching rules for instances in a specified compartment. For example,
```
ALL {instance.compartment.id = 'ocid1.compartment.oc1..aaaaaaaabgr34tpuanpvq6xfb667nsmy2jz45zj6dexojhxdsv4mjayem3cq'} 
```
For more information, refer to Create Dynamic Groups and Policy.
Navigate to Identity -> Policies -> Create Policy to create policy statements as specified below :
If you set policy at:
- ODI compartment level, then all ADW/ATP instances from the compartment where ODI instance is created are listed.
  For example - To List ADW/ATP instances only from the ODI instance compartment, you have to setup the following policy:
```
Allow dynamic-group odi_group to inspect autonomous-database-family in compartment odi
Allow dynamic-group odi_group to read autonomous-database-family in compartment odi
Allow dynamic-group odi_group to inspect compartments in compartment odi
```
- ODI tenant level, then all ADW/ATP instances from all the compartments of the tenancy are listed.
  For example - To list ADW/ATP instances from all the compartments of tenancy, you have to setup the following policy:
```
Allow dynamic-group odi_group to inspect autonomous-database-family in tenancy
Allow dynamic-group odi_group to read autonomous-database-family in tenancy
Allow dynamic-group odi_group to inspect compartments in tenancy
```
To configure email delivery service for specified groups on Oracle Cloud Marketplace:
An email approved sender must be in a group that has IAM policy permissions to send emails. An approved sender must be in a compartment with permissions to manage approved senders. You have to create a policy to manage approved senders in the entire tenant, if the approved senders exist in root compartment.

Add the following policy statement to enable odi_group to manage approved senders:
```
Allow dynamic-group odi_group to use approved-senders in compartment odi
```

Creating an Oracle Cloud Infrastructure Policy in an Identity Domain

Create a policy to grant permissions to users in a domain group to work with Oracle Integration instances within a specified tenancy or compartment.

Note:

This topic applies only to cloud accounts that use identity domains. See About Setting Up Users and Groups.

Open the navigation menu and click Identity & Security. Under Identity, click Policies.
Click Create Policy.
In the Create Policy window, enter a name (for example, IntegrationGroupPolicy) and a description.

In the Policy Builder, select Show manual editor and enter the required policy statements.

Syntax:

allow group domain-name/group_name to verb resource-type in compartment compartment-name
allow group domain-name/group_name to verb resource-type in tenancy

Example: allow group admin/oci-integration-admins to manage integration-instance in compartment OICCompartment

Note:

If you omit the domain name, the default domain is assumed.

This policy statement allows the oci-integration-admins group in the admin domain to manage instance integration-instance in compartment OICCompartment.

You can create separate groups for different permissions, such as a group with read permission only.

Want to learn more about policies? See How Policies Work and Policy Reference, or click Help in the window.

When defining policy statements, you can specify either verbs (as used in these steps) or permissions (typically used by power users).

The read and manage verbs are most applicable to Oracle Integration. The manage verb has the most permissions (create, delete, edit, move, and view).

Verb	Access
`read`	Includes permission to view Oracle Integration instances and their details.
`manage`	Includes all permissions for Oracle Integration instances.

If desired, you can add a policy to allow members of the group to view message metrics, as described in Viewing Message Metrics.

For example:

allow group oci-integration-admins to read metrics in compartment OICPMCompartment
If you intend to use custom endpoints, add one or more additional policy statements. Otherwise, skip this step.

Add policies that specify the compartment in which vaults and secrets reside and allow the admin group to manage secrets in it. See Configure a Custom Endpoint for an Instance.

Note that you should specify the resource to return in resource-type, as described in Details for the Vault Service. Also note that Oracle Integration requires the read verb only but manage is recommended if the same group will also be administering the secrets (uploading/lifecycle operations).

Examples::
- allow group admin/oci-integration-admins to manage secrets in compartment SecretsCompartment
- allow group admin/oci-integration-admins to manage vaults in compartment SecretsCompartment
Click Create.

The policy statements are validated and syntax errors are displayed.

1.4 Connecting to ODI Compute Instance

Note:

This section is applicable only for Advanced administrative users.

You can connect to an ODI compute instance by using a Secure Shell (SSH) connection. Most Linux distributions include an SSH client by default. For Windows, you can download a free SSH client called PuTTY from http://www.putty.org.

To connect to your ODI compute instance from linux,
- Log in to your instance using SSH.
- Use the following command to set the file permissions so that only you can read the file:
```
$ chmod 400 <private_key>
```
  where <private_key> is the full path and name of the file that contains the private key associated with the instance you want to access.
- Use the following SSH command to access the instance.
```
$ ssh –i <private_key> <username>@<public-ip-address>
```
  where
  - <private_key> is the full path and name of the file that contains the private key associated with the instance you want to access.
  - <username> is the default name for the instance. The default user name is oracle.
  - <public-ip-address> is your instance IP address that you retrieved from the Console.
To connect to your ODI compute instance from windows,
- Open putty.exe.
- In the Category pane, select Window, and then select Translation.
- In the Remote character set drop-down list, select UTF-8. The default locale setting on Linux-based instances is UTF-8, and this configures PuTTY to use the same locale.
- In the Category pane, select Session and enter the following:
  1. Host Name (or IP address):<username>@<public-ip-address> , where <username> is the default name for the instance. For Oracle Linux and CentOS images, the default user name is oracle. For the Ubuntu image, the default name is ubuntu and <public-ip-address> is your instance public IP address that you retrieved from the console.
  2. Port: 22
  3. Connection type: SSH
- In the Category pane, expand Connection, expand SSH, and then click Auth.
- Click Browse, and then select your private key.
- Click Open to start the session.
If this is your first time connecting to the compute instance, you might see a message that the server's host key is not cached in the registry. Click Yes to continue the connection.

1.5 Accessing the ODI Compute Instance

To access ODI apps through VNC, do the following:

Log in to the provisioned Oracle Data Integrator instance on Oracle Cloud Marketplace using SSH as opc user:
```
ssh –i <private_key> opc@<IP Address>
```

Execute the following firewall commands to open the VNC ports:

sudo firewall-cmd --permanent --new-service=odissh 
sudo firewall-cmd --permanent --service=odissh --set-description="ODI SSHserver" 
sudo firewall-cmd --permanent --service=odissh --add-port=5901-5905/tcp 
sudo firewall-cmd --permanent --add-service=odissh 
sudo firewall-cmd –reload

Install a VNC viewer on your local computer.
Use SSH to connect to the compute instance running the Oracle Data Integrator Image, as described in Connecting to ODI Compute Instance.
On your local computer, connect to your instance and create a ssh tunnel for port 5901 (for display number 1):
```
$ ssh -L 5901:localhost:5901 –i id_rsa oracle@<IP Address>
```
On your local computer, for the VNC to work, add an Ingress rule as follows:
```
No 0.0.0.0/15 TCP All 5901 TCP traffic for ports: 5901
```
On your local computer, start a VNC viewer and establish a VNC connection to localhost:1.
Enter the VNC password that you had provided during the stack creation.
For connecting multiple users, after the vncpasswd utility exits, start the VNC server by typing vncserver. This will start a VNC server with display number 1 for the oracle user, and the VNC server starts automatically if your instance is rebooted. For example vncserver@:2 or vncserver@:3.

To start developing your data flows or data mappings/transformations, launch studio from the available options.

From the Applications menu, navigate to Programming -> ODI Studio,
or
Double click the short icon for ODI Studio present in your Desktop,
or
Navigate to the location $MW_HOME/oracle/odi/studio/bin/odi in the VNC.
Connect to the repository with already populated login credentials. The Login Name value varies based on the selected repository. For ADB repository, the Login Name is ODI_ADW_REPO and for MySQL Embedded repository it is ODISA_MYSQL.
Post successful configuration, click Topology navigator -> Technologies -> Oracle to check if the newly created data server is available for use.
In ODI studio, navigate to Topology -> Physical Architecture -> Agent -> OracleDIAgent1 and click Test, to check if the Standalone Agent is working.
