Plan Your DR Implementation

Prepare your tenancy to use Oracle Cloud Infrastructure Full Stack Disaster Recovery Service by reviewing the Get Started with Full Stack Disaster Recovery guide.

Prepare Your Tenancy

For the use cases described in this playbook, perform the following:

1. Verify that OCI Full Stack Disaster Recovery Service is available in your primary and standby regions.
2. Prepare Standard Object Storage Buckets for Operation Logs in each region to contain logs. Use a separate dedicated bucket for each disaster recovery (DR) Protection Group, and reserve it exclusively for logs.
   Don't set up replication for this object store bucket and don't use it to write other data. Ensure that the object store bucket is writable by the user running the DR plans.
3. For Oracle Base Database Service, if you don’t already have it, prepare a vault in the primary and standby regions with a secret that contains the database admin password in each one.
4. Setup the following OCI Identity and Access Management policies to your administrator’s group, if it does not already have them:
   1. Policies for OCI Full Stack Disaster Recovery Service
   2. Policies for OCI Compute service
   3. Policies for Oracle Cloud Agent
   4. Policies for the database you are using (Oracle Exadata Database Service on Dedicated Infrastructure, Oracle Base Database Service, or Oracle Autonomous Database Serverless)
   5. Policies for OCI Object Storage service
   6. Policies for OCI Vault service

Prepare Block Volume Groups

If you're using the Oracle Cloud Infrastructure Block Volumes disaster recovery cross-region replica model, then you'll need to prepare your block volume groups.

Note:

This step only applies to the Disaster Recovery model based on OCI Block Volumes cross-region replication. This step does NOT apply to Disaster Recover models based on “OCI File Storage with rsync” and “Database File System (DBFS)” methods for configuration replication.

OCI Full Stack Disaster Recovery Service manages the replica of the block volumes using Block Volume Groups. When you use the Disaster Recovery model based on OCI Block Volumes cross-region replica, use Block Volume Groups and configure the cross-region replica at the Block Volume group level.

If you already setup the DR based on Block Volumes cross-region replication as described in the documents Oracle WebLogic Server for Oracle Cloud Infrastructure, Disaster Recovery Production and DR in the Oracle Cloud Infrastructure (OCI) or SOA Suite on Oracle Cloud Infrastructure Marketplace Disaster Recovery, Production and Disaster Recovery in the Oracle Cloud Infrastructure (OCI), then you have already defined the Volume Groups in primary region and the cross-region replica is configured.

1. If your compute instances are located in more than one availability domain (AD), then verify that you have one Block Volume Group defined in each AD.
2. Verify that the cross-region replica is set in the Volume groups instead of in the individual Block Volumes.
3. Verify that the boot volumes are NOT in the Volume groups because they must not be replicated.
