Oracle by Example branding Create a Non-JRF Instance Using Oracle WebLogic Server for Oracle Cloud Infrastructure with an Existing VCN

section 0Before You Begin

This 45-minute tutorial shows you how to create a non-Java Required Files (JRF) instance for Oracle WebLogic Server using the Marketplace in the Oracle Cloud Infrastructure.

Background

Oracle WebLogic Server for Oracle Cloud Infrastructure can create a domain without JRF components. Oracle WebLogic Server for Oracle Cloud Infrastructure is accessed as a collection of applications in the Oracle Cloud Infrastructure Marketplace.

Oracle Cloud Infrastructure Marketplace is an online store that's available in the Oracle Cloud Infrastructure Console. When you launch an Oracle WebLogic Server for Oracle Cloud Infrastructure application from Marketplace, it prompts you for some basic information, and then directs you to Resource Manager to complete the configuration of your Oracle WebLogic Server domain and supporting cloud resources.

Oracle Cloud Infrastructure Vault (formerly known as Key Management) enables you to manage sensitive information using vaults, keys, and secrets when creating an Oracle WebLogic Server domain. A vault is a container for encryption keys and secrets. A standard vault is hosted on a hardware security module (HSM) partition with multiple tenants, and uses a more cost-efficient, key-based metric for billing purposes.

A virtual private vault provides greater isolation and performance by allocating a dedicated partition on an HSM. Secrets store credentials such as required passwords for a new domain. You use an encryption key in a vault to encrypt and import secret contents to the vault. Secret contents are based64-encoded. Oracle WebLogic Server for Oracle Cloud Infrastructure uses the same key to retrieve and decrypt secrets when creating the domain.

This tutorial uses the Oracle WebLogic Suite BYOL application along with an existing VCN and an existing subnet to provision a non-JRF domain in WLSDRCompartment. The compute instances, networks, and the other resources that are provisioned by Oracle WebLogic Server for Oracle Cloud Infrastructure for your Oracle WebLogic Server domain are created in the WLSDRCompartment.

This tutorial creates a compartment-level Oracle Cloud Infrastructure policy that enables you to work with resources and create resources in WLSDRcompartment.

What Do You Need?

  • An Oracle Cloud Infrastructure cloud tenant.
  • An Oracle Cloud Infrastructure user name and password. You must belong to at least one group.

    You must be an Oracle Cloud Infrastructure administrator. If you are not an administrator, you must be able to create dynamic groups and policies, use secrets, and view tenancies in your tenancy.

  • A dynamic group that lists the OCID of the compartment in which users who are not administrators can create domains. The Oracle Cloud Infrastructure administrator creates this dynamic group.

    See Create Root Policies and Create Dynamic Groups and Policies.


section 1Create a Compartment

  1. Sign in to the Oracle Cloud Infrastructure Console.
  2. At the top of the Console, to switch the region, select a different region from the Region menu. The instance is created in the selected region.
  3. Click the navigation menu Menu icon, select Identity & Security. Under Identity, click Compartments.
  4. On the Compartments page, click Create Compartment.
  5. For Name, enter WLSDRCompartment.
  6. Enter the Description for the compartment.
  7. Select a compartment from the Parent Compartment drop-down list.

    You may also select the default root compartment of the tenancy as the Parent Compartment.

  8. Click Create Compartment.

section 2Create an Oracle Cloud Infrastructure Policy

If you do not have Administrator privileges, do the following to create an Oracle Cloud Infrastructure policy that enables you to work with or create resources in the WLSDRCompartment compartment:

  1. Sign in to the Oracle Cloud Infrastructure Console.
  2. Click the navigation menu Menu icon, select Identity & Security. Under Identity, click Policies.

    Note: Ensure that you create the policy within WLSDRCompartment compartment that you have created earlier for the non-JRF instance.

  3. Click Create Policy.
  4. Enter the policy Name and Description.
  5. From Policy Options, select the Policy Use Cases and Common Policy Templates.

    The policy builder displays the policy statements for the selected use case and policy template.

  6. Select the Groups and Location.

    Now, the policy statement is displayed for the selected groups and location. For example, if the groups is Adminstrators and the location is WLSDRCompartment, the policy statement is Allow Administrators to manage users in WLSDRCompartment.

    You can modify the policy statements using the Customize (Advanced) option. For a sample compartment policy, download the text file.

  7. Click Create.

section 3Create an SSH Key Pair

On a UNIX or UNIX-like platform, do the following:

  1. Run the following ssh-keygen command:

    ssh-keygen -b 2048 -t rsa

  2. In the prompt, enter the path to the file in which you want to save the key. If you wish to accept the default path and file name, press Enter.
  3. In the prompt, enter a passphrase.

    The passphrase is not mandatory. However, it is recommended that you specify a passphrase to protect your private key against unauthorized use.

  4. When prompted, enter the passphrase again to confirm it.

    The command generates an SSH key pair consisting of a public key and a private key. When you create a domain using Oracle WebLogic Server for Oracle Cloud Infrastructure, you specify the public key. You then access the compute instances from an SSH client using the private key.

On a Windows platform, you can use the PuTTY Key Generator utility. See Creating a Key Pair in the Oracle Cloud Infrastructure documentation.
