WebLogic non JRF domain

This solution creates single/multi node WebLogic cluster with Oracle Cloud Infrastructure File Storage service (FSS) fronted by a load balancer.

This topology creates WebLogic cluster in a private subnet. Following regional subnets are created under new virtual cloud network (VCN).

  • WebLogic regional private subnet
  • Bastion regional public subnet
  • Load balancer frontend public subnet
  • Mount target regional private subnet

Full Topology Diagram

The above diagram shows a topology that includes most of the components supported by the Terraform scripts. In this scenario, the WebLogic servers are created in a private subnet. To access the applications running on WebLogic, a new OCI load balancer in public regional subnet will be created. A bastion instance with a public ip address is provisioned to allow access to the WebLogic VMs in the private subnet. New file system (FSS) and mount target will be created in a private subnet to support mounting shared storage for WebLogic instance data and middleware. The file system (FSS) will be mounted on each WebLoogic instance at /u01/shared.

Before You Begin with OCI Terraform stack for WebLogic Server

Refer to the documentation for the pre-requisite steps to use the OCI Terraform stack for WebLogic Server.

Workspace Checkout

  • Install the latest version of git from http://git-scm.com/downloads
  • For Linux and Mac: Add git to the PATH
  • Clone the code using the command:
git clone https://github.com/oracle-quickstart/oci-weblogic-server.git

Organization

The directory oci-weblogic-server/solutions/non_jrf consists of the following terraform files:

  • nonjrf_instance.tfvars - WebLoogic instance, bastion instance , and network configuration
  • lb.tfvars - load balancer configuration
  • fss.tfvars - file system configuration

The directory oci-weblogic-server/solutions/common consists of the following:

  • tenancy.tfvars - tenancy configuration

The files in the oci-weblogic-server/images directory contain the values of the images for the different combinations of WebLogic edition and pricing. In this solution, the file mp_image_ee_byol.tfvars is used to create a WebLogic Enterprise Edition, BYOL instance. Specify a different file to use a different edition and/or pricing.

See the License section for more information to help you decide which mp_image*.tfvars_ file to use.

Using the terraform command line tool

cd oci-weblogic-server/terraform

Initialize the terraform provider plugin

terraform init

Update the variable values in tfvars files under directories terraform/solutions/common and terraform/solutions/non_jrf according to the user specific values. Invoke apply passing all *.tfvars files as input

terraform apply -var-file=../solutions/common/tenancy.tfvars -var-file=images/mp_image_ee_byol.tfvars -var-file=../solutions/non_jrf/nonjrf_instance.tfvars -var-file=../solutions/non_jrf/lb.tfvars -var-file=../solutions/non_jrf/fss.tfvars

To destroy the infrastructure

terraform destroy -var-file=../solutions/common/tenancy.tfvars -var-file=images/mp_image_ee_byol.tfvars -var-file=../solutions/non_jrf/nonjrf_instance.tfvars -var-file=../solutions/non_jrf/lb.tfvars -var-file=../solutions/non_jrf/fss.tfvars

Important: Refer to documentation for steps to perform before running terraform destroy.
