Before You Begin
This 45-minute tutorial shows you how to use Oracle Cloud Infrastructure Marketplace and a DB System database to provision an Oracle WebLogic Server domain and cluster that includes Java Required Files (JRF) components. The tutorial also shows you how to create a Java Database Connectivity (JDBC) custom data source for the DB System database.
You can use Oracle WebLogic Server for Oracle Cloud Infrastructure applications in the Oracle Cloud Infrastructure Marketplace to provision a cluster of WebLogic Server nodes. The first node hosts the administration server for the domain along with the first managed server. This service can also provision a load balancer to distribute application traffic across the servers in your cluster. Marketplace uses Oracle Resource Manager to provision the network, compute instances, and load balancer as a single unit called a stack.
Oracle Cloud Infrastructure Marketplace offers separate services for:
- Oracle WebLogic Server Standard Edition
- Oracle WebLogic Server Enterprise Edition - includes clustering
- Oracle WebLogic Suite - includes Oracle Coherence for increased performance and scalability, and Active Gridlink for RAC for advanced database connectivity
This tutorial uses Oracle WebLogic Server for Oracle Cloud Infrastructure to create subnets in an existing virtual cloud network (VCN) to support WebLogic Server 12c with a load balancer. You can also use existing subnets if desired. By default the WebLogic Server subnet is public and accessible from external clients, but Oracle WebLogic Server for Oracle Cloud Infrastructure can provision WebLogic Server in a private subnet. Oracle WebLogic Server for Oracle Cloud Infrastructure also supports provisioning WebLogic Server in a different VCN than the one used by the database.
This tutorial creates a WebLogic Server JRF-enabled domain that includes the Java Required Files components for building applications with Oracle Application Development Framework (ADF). An existing Oracle Cloud Infrastructure DB System or Oracle Autonomous Transaction Processing (ATP) database is required in order to provision a JRF-enabled domain. This tutorial uses a DB System 12.x database to contain the JRF components.
Provisioning a domain in Oracle WebLogic Server for Oracle Cloud Infrastructure requires one or more secrets in Oracle Cloud Infrastructure Vault. Secrets store one or more passwords you would require when creating a WebLogic Server cluster. This tutorial uses a standard vault, which 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. Each type of vault has a separate service limit in your Oracle Cloud Infrastructure tenancy. The limit for secrets spans all vaults. See Service Limits and Oracle Cloud Infrastructure Vault FAQ.
You can estimate the cost of the resources and services that you want to use to provision your instance. See Oracle Cloud Cost Estimator.
What Do You Need?
- Your 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.
Controlled access to these tenancy resources are defined in a root-level policy that is typically created by the Oracle Cloud Infrastructure administrator. For a sample root-level policy, download the text file.
- An Oracle Cloud Infrastructure compartment.
This tutorial uses a single compartment, which contains the DB System database you intend to use for the JRF-enabled domain, and the compute instances, load balancer, and network resources that will be created for the domain.
- 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. For a sample dynamic group, download the text file and replace the value with your compartment OCID. For dynamic group policies, see this text file.
- A compartment-level Oracle Cloud Infrastructure policy that
enables you to work with resources and create resources in the
compartment you intend to use.
If you are not an administrator:
- You must be able to access Marketplace applications and Resource Manager to create stacks and jobs, compute instances, networks (optional), and load balancers (optional) in the compartment.
- You must also be able to create vaults, keys, and secrets in the compartment.
- You must be able to list databases in the compartment that contains your database, and to create network resources in the same compartment.
- An SSH public key and corresponding private key.
- A bare metal or virtual machine DB System 12.x or higher
database. See Creating Bare Metal and Virtual Machine DB
This tutorial uses a virtual machine DB System database for a JRF-enabled domain based on Oracle WebLogic Server 12c. See the text file. You'll need the database name and host name for your DB System database. You'll also need the PDB name, the compartment and VCN where the database is located, and the private key of the SSH key pair that was used to create the database.
By default Oracle WebLogic Server for Oracle Cloud Infrastructure creates a security list in the VCN on which the database to contain the JRF components is created. This security list allows the WebLogic Server subnet to access the database port.
- (Optional) A database user other than SYS for the custom data source.
