The OCI Terraform stack for WebLogic Server allows you to create and configure a WebLogic domain in Oracle Cloud Infrastructure (OCI), in minutes. It will create and/or configure multiple OCI services such as Compute, Network, OCI Database, Autonomous Database, Identity Cloud Service, Logging, File System, Application Performance Monitoring and Autoscaling. The WebLogic domain created can be scaled by updating a terraform variable to indicate the desired number of nodes and re apply the stack or auto-scaling can be configured to automatically adapt to different workloads in real time.
The OCI Terraform stack for WebLogic Server is available through the Oracle Quick Start or through the Oracle Cloud Infrastructure Marketplace as one of the multiple Oracle WebLogic Server for OCI applications. After launching one of these applications, you use a simple wizard interface to configure and provision your domains along with any supporting cloud resources like compute instances, networks and load balancers.
For more details about deploying the OCI Terraform stack for WebLogic Server through the OCI Marketplace, visit the "Using Oracle WebLogic Server for OCI" guide.
The OCI Terraform stack for WebLogic Server offers many options to customize your environment, to create new resources or configure existing resources or services such as Network, Oracle Database, Oracle Identity Cloud Service, Logging, File System, etc.
The solutions directory contains examples of different topologies that can be created with this Terraform template, with sample tfvars files, and instructions to create the stack.
The following topologies are included:
| Solution | Features |
|---|---|
| non_jrf |
|
| jrf |

Whether you use Terraform CLI, ORM or the Marketplace to create a stack, you need to perform some pre-requisites. Refer to the documentation for the pre-requisite steps to use the OCI Terraform stack for WebLogic Server.
For pre-requisites specific to Terraform CLI and ORM, see their corresponding section.
The WebLogic Server for OCI stack applications available in the Marketplace are:
- Oracle WebLogic Server Enterprise Edition (UCM)
- Oracle WebLogic Suite (UCM)
- Oracle WebLogic Server Standard Edition (BYOL)
- Oracle WebLogic Server Enterprise Edition (BYOL)
- Oracle WebLogic Suite (BYOL)
To create, manage and destroy the OCI Terraform stack for WebLogic Server as WebLogic Server for OCI using the Marketplace, follow the instructions in the documentation.
You need to install the following software in your computer to create a stack using Terraform CLI:
- Git. Install the latest version
- Terraform. The scripts in this Quick Start requires Terraform version >= 1.1.2, < 1.2.0
First, get a local copy of this repo. You can make that with the commands:
git clone https://github.com/oracle-quickstart/oci-weblogic-server.git
cd oci-weblogic-server/terraform
lsExample output:
$ git clone https://github.com/oracle-quickstart/oci-weblogic-server.git

$NOTE: All the terraform commands must be run from the terraform directory.
Next, initialize the directory with the module in it. This makes the module aware of the OCI provider. You can do this by running:
terraform initExample output:
$ terraform init

If you'd like to know more about provider signing, you can read about it here:
https://www.terraform.io/docs/cli/plugins/signing.html
Terraform has created a lock file .terraform.lock.hcl to record the provider
selections it made above. Include this file in your version control repository
so that Terraform can guarantee to make the same selections by default when
you run "terraform init" in the future.
Terraform has been successfully initialized!
You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
First, you need to set the image variables, depending on which WebLogic edition and type of license you want to use, BYOL license or UCM license, when creating the stack.
The following files contain the values for those variables:
- mp_image_se_byol.tfvars: WebLogic Standard Edition - BYOL
- mp_image_ee_byol.tfvars: WebLogic Enterprise Edition - BYOL
- mp_image_ee_ucm.tfvars: WebLogic Enterprise Edition - UCM
- mp_image_suite_byol.tfvars: WebLogic Suite - BYOL
- mp_image_suite_ucm.tfvars: WebLogic Suite - UCM
To use one of the files above:
- Copy the file from the
terraform/imagesdirectory, to theterraformdirectory - Rename the file from
terraform/mp_image_<edition>_<license>.tfvarstoterraform/mp_image_<edition>_<license>.auto.tfvars
For example, if you want to create a WebLogic Enterprise Edition UCM stack, copy the file terraform/images/mp_image_ee_ucm.tfvars
to terraform/mp_image_ee_ucm.auto.tfvars
Next, you need to configure variables to drive the stack creation. This can be done by creating a
terraform.tfvars file in the terraform directory, using variables copied from the tfvars files from one of the solutions
into the terraform.tfvars file.
Make sure the plan looks good. Once you created terraform.tfvars in the terraform directory, just run:
terraform planIf terraform plan is successful, you can run terraform apply to deploy the stack:
terraform applyYou'll need to enter yes when prompted.
After the stack creation is complete, if you need to make changes to your stack (adding a new VM for example), you can edit
the variables in your terraform.tfvars file, and run the following commands:
terraform plan
# If the plan looks OK, run apply.
terraform applyNOTE: Not all variables can be changed after a stack is deployed.
Important: Refer to documentation for steps to perform before running terraform destroy.
When you no longer need the deployment, you can run this command to destroy it:
terraform destroyYou'll need to enter yes when prompted.
Oracle Cloud Infrastructure Resource Manager (ORM) allows you to manage your Terraform configurations and state. To simplify getting started, the Terraform zip files for use with ORM are created as part of each release.
If you want to build the zip file to create an ORM stack, you need the following software:
Linux
- No additional software is required
Mac OS
- GNU sed
Windows
- Git bash (included in Git for Windows) or any other software that allows you to run bash scripts in Windows
- The build scripts use the
zipcommand. This is an example of how you can use a program like 7-zip with the build scripts
- Install 7-zip
- Locate the file 7z.exe. Copy it to a directory that can be added to your path (e.g. ~/bin)
- Create a script called
zipin the same directory (e.g. ~/bin) with the following content:
#!/bin/bash
7z.exe a $@- Add the directory where you put the files (e.g. ~/bin) in your PATH
- Verify zip command is recognized:
$ zip
7-Zip 22.01 (x64) : Copyright (c) 1999-2022 Igor Pavlov : 2022-07-15
Command Line Error:
Cannot find archive nameTo build the zip file to create an ORM stack, run the builds/build_mp_bundles.sh script.
$ cd builds/
$ ./build_mp_bundles.sh
Build the Oracle Resource Manager (ORM) bundles to deploy in Marketplace
Arguments: build_mp_bundles.sh -e|--edition <EE|SUITE|SE> -v|--version <12.2.1.4|14.1.1.0> -t|--type <UCM|BYOL> --all
options:
-e, --edition WebLogic edition. Supported values are EE, SUITE, or SE. Optional when --all option is provided
-v, --version WebLogic version. Supported values are 12.2.1.4 or 14.1.1.0. Optional when --all option is provided
-t, --type Type of bundle. Supported values are UCM or BYOL. Optional when --all option is provided
--all All bundlesFor example, to create the zip file for a WebLogic 12.2.1.4 Enterprise Edition stack with BYOL license, run the following command:
cd builds
./build_mp_bundles.sh --edition EE --version 12.2.1.4 --type BYOLThe zip files are generated in the builds/binaries directory.
Follow these steps to create
a ORM stack, using either a zip file from one of the releases,
or a zip file generated manually with the build_mp_bundles.sh script.
After you create the stack, you can run a plan job
to validate the resources that will be created.
If the plan looks good, you can run an apply job
to deploy the stack.
After the stack creation is complete, you can manage the domain.
Important: Refer to documentation for
steps to perform before running a destroy job.
When you no longer need the deployment, you can run a
destroy job to destroy the stack.
Refer to documentation to identify common problems and learn how to diagnose and solve them.
