Implementing Data Replication and Disaster Recovery with OCI Autonomous Database

Posted on by Osama Mustafa in Uncategorized

Introduction

  • Overview of OCI Autonomous Database and its capabilities.
  • Importance of data replication and disaster recovery for business continuity.

Step-by-Step Guide

  1. Setting Up OCI Autonomous Database
  • Creating an Autonomous Database Instance:
oci db autonomous-database create --compartment-id <compartment_OCID> --db-name "MyDatabase" --cpu-core-count 1 --data-storage-size-in-tbs 1 --admin-password "<password>" --display-name "MyAutonomousDB" --db-workload "OLTP" --license-model "BRING_YOUR_OWN_LICENSE" --wait-for-state AVAILABLE

2. Configuring Data Replication

  • Creating a Database Backup:
oci db autonomous-database backup create --autonomous-database-id <db_OCID> --display-name "MyBackup" --wait-for-state COMPLETED

3. Setting Up Data Guard for High Availability:

  • Creating a Data Guard Association:
oci db autonomous-database create-data-guard-association --compartment-id <compartment_OCID> --primary-database-id <primary_db_OCID> --standby-database-id <standby_db_OCID> --display-name "MyDataGuardAssociation"

4. Implementing Disaster Recovery

  • Configuring Backup Retention Policies:
  • Set up automated backups with a specific retention period through the OCI Console or CLI:
oci db autonomous-database update --autonomous-database-id <db_OCID> --backup-retention-period 30
  • Restoring a Database from Backup:
oci db autonomous-database restore --autonomous-database-id <db_OCID> --restore-timestamp "2024-01-01T00:00:00Z" --display-name "RestoredDatabase"

4. Testing and Validating Disaster Recovery

  • Performing a Failover Test:
    • Failover to Standby Database:
oci db autonomous-database failover --autonomous-database-id <standby_db_OCID>
  • Verifying Data Integrity:
    • Connect to the standby database and validate data consistency and application functionality.

5. Automating and Monitoring

  • Automating Backups and Replication:
    • Use OCI’s built-in scheduling features to automate backup creation and data replication.
  • Monitoring Database Health and Performance:
  • Use OCI Monitoring to set up alarms and dashboards for tracking the health and performance of your Autonomous Database.
  • Example Alarm:
oci monitoring alarm create --compartment-id <compartment_OCID> --display-name "HighIOWaitTime" --metric-name "io_wait_time" --threshold 1000 --comparison ">" --enabled true

Osama considered as one of the leaders in Cloud technology, DevOps and database in the Middle-East. I have more than ten years of experience within the industry. moreover, certfied 4x AWS , 4x Azure and 6x OCI, have also obtained database certifications for multiple providers. In addition to having experience with Oracle database and Oracle products, such as middle-ware, OID, OAM and OIM, I have gained substantial knowledge with different databases. Currently, I am architecting and implementing Cloud and DevOps. On top of that, I'm providing solutions for companies that allow them to implement the solutions and to follow the best practices.
