Create a Basic Domain in a Private Subnet

When you use Oracle WebLogic Server for Oracle Cloud Infrastructure to create a stack and assign the Oracle WebLogic Server compute instances to a private subnet, the instances are not accessible from the public Internet.

To access the virtual machines (VMs) created in the private subnet, a bastion host is required. You must create a bastion host with a FastConnect or a VPN connection before you create a domain or you must choose to have a bastion host created for you.

All Oracle WebLogic Server 11g domains include the Java Required Files (JRF) components and require a database. To create a domain that uses a database for JRF components, see Create a JRF-Enabled Domain.

Before you create a domain, you must first perform the following tasks:
  • Create a compartment. See Create a Compartment.
  • Create an SSH key. See Create an SSH Key.
  • Create an encryption key to use for secrets. See Create an Encryption Key.
  • Create secrets for the passwords you want to use for the domain. You will need to enter the OCID of a secret. See Create Secrets for Passwords.
  • Create a confidential application in Oracle Identity Cloud Service if you want to use Oracle Identity Cloud Service for authentication in the domain. You will need the client ID and client secret for this confidential application. See Create a Confidential Application. You will also need to create a secret for the client secret and copy the OCID. See Create Secrets for Passwords.
  • Create a FastConnect or a VPN connection if you want to use your own bastion host to administer your Compute instances. See VPN Connect or FastConnect in the Oracle Cloud Infrastructure documentation.

Oracle WebLogic Server for Oracle Cloud Infrastructure can create the virtual cloud network (VCN) and subnets for your new domain. If you want to use an existing VCN or existing subnets for the domain, then they must meet certain requirements. See:

Topics:

Launch a Stack

Sign in to Marketplace and specify initial stack information.

  1. Sign in to the Oracle Cloud Infrastructure Console.
  2. Click the navigation menu Navigation Menu icon, select Marketplace, and then click All Applications.
  3. Select an application that matches the edition of Oracle WebLogic Server that you want to provision, and also uses the type of billing you want (Universal Credits or Bring Your Own License).
    • Oracle WebLogic Server Standard Edition BYOL
    • Oracle WebLogic Server Enterprise Edition BYOL
    • Oracle WebLogic Server Enterprise Edition UCM
    • Oracle WebLogic Suite BYOL
    • Oracle WebLogic Suite UCM
  4. Select a version of Oracle WebLogic Server 12c.
    The latest 12.2.1.4 patch level is the default.

    If multiple builds are available for the same patch level (.01, .02, .03, and so on), choose the latest build.

  5. Select the compartment in which to create the stack.
    By default the stack compartment is used to contain the domain compute instances and network resources. If later on you specify a network compartment on the Configure Variables page of the Create Stack wizard, then only the compute instances are created in the stack compartment that you select here.
  6. Select the Oracle Standard Terms and Restrictions check box, and then click Launch Stack.
    The Create Stack wizard is displayed.

Specify Stack Information

Specify the name, description, and tags for the stack.

  1. On the Stack Information page of the Create Stack wizard, enter a name for your stack.
  2. Enter a description for the stack (optional).
  3. Specify one or more tags for your stack (optional).
  4. Click Next.
    The Configure Variables page opens.

Configure WebLogic Instance Parameters

Specify the parameters needed to configure the WebLogic instance domain.

  1. In the WebLogic Server Instance section, enter the resource name prefix.
    The maximum character length is 16.
    This prefix is used by all the created resources.
  2. Select the WebLogic Server shape for the compute instances.
    The following shapes are supported:

    • Standard: VM.Standard2.x, VM.Standard.E2.x, BM.Standard2.x, BM.Standard.E2.x

    • Flex: VM.Standard.E3.Flex

    Note:

    In regional subnets, select the WebLogic Server shape that has sufficient service limits for an availability domain, else the provisioning fails.

  3. Select the OCPU count for compute instances.

    Note:

    You can specify the OCPU count only for the VM.Standard.E3.Flex shape, and the maximum number of OCPUs that you can specify is 64. The memory, network bandwidth, and number of Virtual Network Interface Cards (VNICs) scale proportionately with the number of OCPUs.

  4. Enter the SSH public key, by either uploading the SSH key file or pasting the contents of your SSH public key file.
  5. Select the number of managed servers you want to create. You can specify up to 4 if you're using WebLogic Server 11g Standard Edition. For all other editions and versions, you can specify up to 8 nodes, which can be scaled out to 30 when you edit the domain.
    The managed servers will be members of a cluster, unless you selected WebLogic Server Standard Edition.
  6. Enter a user name for the WebLogic Server administrator.
  7. Enter the OCID of the secret that contains the password for the WebLogic Server administrator. See Create Secrets for Passwords.

Configure Advanced Parameters for a Domain

You can optionally specify additional parameters by selecting WLS Instance Advanced Configuration on the Configure Variables page of the Create Stack wizard.

Select WLS Instance Advanced Configuration if you want to change the default port numbers or remove the sample application.
  • Cluster-related parameters are not applicable if you selected WebLogic Server Standard Edition.
  • There is no sample application if you selected WebLogic Server Standard Edition 11g.
  • The port numbers 9071-9074 are reserved for internal domain communication.

Configure Network Parameters

Define the Virtual Cloud Network (VCN) and subnet configuration for a private domain.

  1. In the WebLogic Server Network section of the Configure Variables page, select the Network Compartment in which to create the network resources for this domain.
    If you don't specify a network compartment, then all the network resources and the domain compute instances are created in the stack compartment that you selected earlier upon launching the stack. Select a network compartment if you want the network resources to be in a different compartment than the compute instances.
  2. Select a Virtual Cloud Network (VCN) strategy:
    • Select Use Existing VCN, and then select the name of the existing VCN.
    • Select Create New VCN, and then enter a name and CIDR for the new VCN.
  3. Select one of the following subnet strategies:
    • Select Use Existing Subnet.
    • Select Create New Subnet.

      Note:

      If you're creating a new VCN, you can only create a new regional subnet.
  4. Select the Subnet Compartment to use for the existing subnet.

    The subnet compartment is different than the VCN compartment. The subnets for the WebLogic Server nodes, load balancer and the bastion node use this same subnet compartment.

    Note:

    You can specify the subnet compartment only if you're using an existing subnet.

  5. If you selected Use Existing VCN as the Virtual Cloud Network (VCN) strategy and Use Existing Subnet as the subnet strategy, then for subnet type, select Use Public Subnet or Use Private Subnet.
  6. For the WebLogic Server subnet, specify one of the following:
    • If you want to use an existing regional subnet, then choose the name of an existing regional subnet from the list of regional and availability domain-specific subnets.
    • If you are creating a new regional subnet, specify a CIDR for the new subnet.

Configure a Bastion

You can configure a bastion compute instance on a public subnet to provide access to the WebLogic Server compute instances on a private subnet. However, creating the bastion node on public subnet is optional.

Note:

  • By default, Provision Bastion Node on Public Subnet is selected when an existing private subnet is selected. If you do not select this option, no status is returned for provisioning, then you must check the status of provisioning by connecting to each compute instance and confirm that the /u01/provStartMarker file exists with details found in the file /u01/logs/provisioning.log file.
  • It is recommended to deselect the Provision Bastion Node on Public Subnet option only in network with fast connect setup.
  • The Provision Bastion Node on Public Subnet option is not available when you are creating a new subnet for a new VCN or existing VCN.

To configure a bastion:

  1. For the bastion host subnet, specify one of the following:
    • If you want to use an existing regional subnet, then choose the name of an existing regional subnet from the list of regional and availability domain-specific subnets.
    • If you are creating a new regional subnet, specify a CIDR for the new subnet.
  2. Select a shape for the bastion compute instance.

Configure a Load Balancer

You have the option to create a load balancer to distribute application traffic to the WebLogic Managed Servers.

To create a load balancer:

  1. Select Provision Load Balancer.
  2. Configure the load balancer network.
    • If you chose to use an existing regional subnet for WebLogic Server, then select an existing regional subnet from the list of regional and availability domain-specific subnets. A load balancer can have only one regional subnet, which is shared between both nodes.
    • If you chose to create a regional subnet for WebLogic Server, then specify a CIDR for the new load balancer subnet.
  3. Select a minimum and maximum flexible load balancer shape.
    By default, the minimum bandwidth size is set to 10Mbps and maximum to 400Mbps.

    Note:

    You can update the shape to a maximum of 8000Mbps. Before you select the maximum bandwidth, ensure to check the available service limit for the flexible load balancer bandwidth.
  4. Select Private Load Balancer if you do not want to assign a public IP address to the load balancer.
    This option is available only if you use a private subnet for WebLogic Server. You cannot create a load balancer in a private subnet.

Create OCI Policies

When you create a basic domain in a private subnet, by default the OCI Policies check box is selected and Oracle WebLogic Server for Oracle Cloud Infrastructure creates a dynamic group and relevant root-level (tenancy) policies for you.

If you are not an administrator, the necessary groups and policies must be in place before you can create a domain.

Before you deselect the check box, ask your administrator to create the required dynamic group and relevant policies, as described in Create a Dynamic Group and Create Policies for the Dynamic Group.

Configure WebLogic Authentication

You have the option to use Oracle Identity Cloud Service to authenticate application users for your domain.

This configuration is only available if the domain meets these requirements:

  • Running WebLogic Server 12c
  • Includes a load balancer

To use Oracle Identity Cloud Service for authentication:

  1. Select Enable Authentication Using Identity Cloud Service.
  2. Enter your Oracle Identity Cloud Service (IDCS) tenant name, which is also referred to as the instance ID.
    This ID is typically found in the URL that you use to access Oracle Identity Cloud Service, and has the format idcs-<GUID>.
  3. Enter the client ID of an existing confidential application in this Oracle Identity Cloud Service instance.
  4. Enter the OCID of the secret that contains the client secret of the confidential application.
  5. If necessary, you can override the default domain name and port that you use to access Oracle Identity Cloud Service, or the default port that is used for the App Gateway software appliance.

Configure Database Parameters

A basic WebLogic Server 12c domain does not require a database.

A database is required only if you want to create a domain that includes the Java Required Files (JRF) components. Do not select the Provision with JRF checkbox if you're not creating a JRF-enabled domain.

All Oracle WebLogic Server 11g domains include the Java Required Files (JRF) components and require a database. To create a domain that uses a database for JRF components, see Create a JRF-Enabled Domain.

Configure a Data Source for an Application Database

When you create an Oracle WebLogic Server for Oracle Cloud Infrastructure domain, you can configure the application database to create a data source configuration that enables you to connect to Oracle Autonomous Transaction Processing or Oracle Cloud Infrastructure Database (DB System).

The database that you connect to is used to contain the schemas for the application database.

You can configure the application database only for Oracle WebLogic Server Enterprise Edition and Oracle WebLogic Suite.

If you are creating a domain for Oracle WebLogic Server 11g:

  • Oracle Autonomous Transaction Processing is not supported.
  • The database must be running Oracle Database 11g or 12.1.

On the Configure Variables page, select the Configure Application Datasource checkbox to display the Database options. Then in the Application Database section, select the Application Database Strategy for your application database and configure the database parameters.

  • If using Autonomous Transaction Processing Database, select or enter the following:
    • The compartment in which you've created the application database.
    • The autonomous database where you want to create the schemas for the application database.
    • The name of an autonomous database user to configure the application database.
    • The OCID of the secret that contains the password for the application autonomous database user to access the selected autonomous database.
    • The service level that the domain should use to connect to the application database for the selected autonomous database.
  • If using Database System, select or enter the following:
    • The compartment in which you've created the application database.
    • The DB system to use for this application database.
    • The compartment in which the application database's VCN is found.
    • The VCN on which you've created the application database. If this VCN is different than the WebLogic Server VCN, they cannot have overlapping CIDRs. For example, you cannot create a domain on VCN 10.0.0.0/16 that uses a database on VCN 10.0.0.1/24.
    • The database home within the selected application database system.
    • The version of the selected database home.
    • The database within the selected DB system where you want to create the schemas for the application database.
    • The Pluggable database (PDB) name, only if the selected application database is running Oracle Database 12c or later.
    • The name of a database user to configure the application database.
    • The OCID of the secret that contains the password for the application database user.
    • The application database listen port (1521 by default)
  • If using Database System, then Oracle WebLogic Server for Oracle Cloud Infrastructure creates a security list in the VCN on which you've created the application database. This security list allows the WebLogic Server subnet to access the application database port. If this step isn't required or you don't have the correct permissions to modify the database network, clear the Create Application Database Security List check box.

Set Local VCN Peering for an Application Database

If you selected different VCNs for the WebLogic Server compute instances and the Oracle Cloud Infrastructure Application Database, you can either disable the local VCN peering or configure the local VCN peering for the Application Database.

If the VCNs for WebLogic Server compute instances and the Oracle Cloud Infrastructure Application Database have been peered before creating the stack for the Oracle WebLogic Server for Oracle Cloud Infrastructure domain. select the Application Database VCN is Already Peered with the WLS VCN checkbox. See Local VCN Peering to peer the VCNs manually. In this case, the stack is provisioned based on the database private IP address.

If the VCNs for WebLogic Server compute instances and the Oracle Cloud Infrastructure Application Database system have not been peered, you can use Oracle WebLogic Server for Oracle Cloud Infrastructure to update the two VCNs so that they can communicate.

Oracle WebLogic Server for Oracle Cloud Infrastructure creates a public subnet in each VCN, and then creates a compute instance in each subnet. These compute instances run software to forward DNS requests across the VCNs.

You cannot use existing subnets for the DNS Forwarder compute instances.

  1. Specify a CIDR for the new subnet in the WebLogic Server VCN.
  2. Specify a CIDR for the new subnet in the application database VCN.
  3. Select a shape for the new DNS Forwarder compute instance in each VCN.

Configure Tags

Oracle WebLogic Server for Oracle Cloud Infrastructure can optionally assign tags to the resources (compute, network, and so on) that it creates for your domain.

Tagging allows you to define keys and values and associate them with resources. You can then use the tags to help you organize and find resources based on your business needs. There are separate fields to tag the stack and to tag the resources created within the stack.

  1. To assign an existing tag, enter the Defined Tag Key and Defined Tag Value.
    Specify the name of a defined tag using the format <namespace>.<key>. For example, Operations.CostCenter.
  2. To assign a free-form tag, enter the Free-Form Tag Key and Free-Form Tag Value.
    Free-form tag keys and values are case sensitive. For example, costcenter and CostCenter are treated as different tags.

Create the Domain Stack

After you have specified the WebLogic instance variables, finish creating the domain stack.

On the Review page of the Create Stack wizard, review the information you have provided, and then click Create.

The Job Details page of the stack in Resource Manager is displayed. A stack creation job name has the format ormjobyyyymmddnnnnnn. (for example, ormjob20190919165004). Periodically monitor the progress of the job until it is finished. If an email address is associated with your user profile, you will receive an email notification. In the Application Information tab, you can directly access the OCI resources using the WebLogic instance IP and the bastion instance IP.

Note:

If there is an error during the creation of the stack, the compute, network, and other resources in the stack are not automatically deleted. If you want to delete the failed stack, see Delete a Domain.

Use Your New Domain

Access and manage your new domain after creating a stack with Oracle WebLogic Server for Oracle Cloud Infrastructure.
