Back Up and Restore a Domain

Oracle WebLogic Server for OKE provides the ability to backup and restore your domain.

Back up a domain:

• By default, every time you run a job, a back up of the domain is created automatically.
• There is no job available to periodically back up your domain.
• You can also manually take a backup by copying the current yaml file to your preferred location. A yaml file has information about the current setup of the domain.

The backups are location at: /u01/shared/weblogic-domains/<domain_name>/backups

A sample backup:

[opc@oracle-admin oracledomain]$ pwd
/u01/shared/weblogic-domains/oracledomain
[opc@oracle-admin oracledomain]$ ll -tR
.:
total 25
-rwxr-xr-x. 1 opc opc 3728 Sep 24 16:14 domain.yaml
drwxr-xr-x. 3 opc opc 1 Sep 24 16:14 backups
-rw-rw-r--. 1 opc opc 4642 Sep 23 17:16 provisioning_metadata.json
-rw-rw-r--. 1 opc opc 1495 Sep 23 16:55 create-domain-inputs.yaml

./backups:
total 1
drwxr-xr-x. 2 opc opc 2 Sep 24 16:14 20-09-24_15-57-44

./backups/20-09-24_15-57-44:
total 16
-rw-r--r--. 1 opc opc 3728 Sep 24 16:14 domain.yaml
-rw-r--r--. 1 opc opc 3725 Sep 24 16:14 prev-domain.yaml

Where:

• prev-domain.yaml, is the previous domain that was running before the current job was completed.
• domain.yaml, is the existing domain after the current job was completed.

Restore a domain:

1. Access the administration compute instance for your domain.

   See Access the Administration Instance.

2. Go to the backup location, where the domain yaml that you want to apply is located.
3. Open the domain yaml and make a note of the image id.
   For example:

   image: "phx.ocir.io/ax8cfrmecktw/oracle/oracle_domain/wls-domain-base:12.2.1.4.200714-200819-20-09-23_14-51-16"

4. Run the following commands to set the required environment variables:

   export wls_domain_namespace=<domain namespace>
   export wls_domain_uid=<domain UID>
   export ocir_url=<region>.ocir.io

5. Run the following command:

   /u01/shared/scripts/pipeline/common/pipeline_common.sh -i <image_id>

   Where, <image_id> is the image id you noted in step 2.

   For example:

   /u01/shared/scripts/pipeline/common/pipeline_common.sh -i phx.ocir.io/ax8cfrmecktw/oracle/oracle_domain/wls-domain-base:12.2.1.4.200714-200819-20-09-23_14-51-16
