Ansible Automation for Oracle RMAN / Apex Restores
- 2. Brief Introduction about Ansible • Ansible is declarative language and not to be seen as a programming language , it does not depend on any compiled scripts like Java, Python • Widely used for SRE Automation • Ansible is a agent less tool which is designed to work with many servers together • Ansible Documentation provides a complete description of various usages and functionalities of ansible https://docs.ansible.com/
- 3. Ansible APEX Restores - My Lab Environment Ansible Control Server Source Server ( running Oracle APEX ) Target Server Ansible Control Server - My MacBook Terminal Source Server RHEL 7 running Oracle 19.3 APEX ( Used a Prebuilt Developer VM from OTN ) Target Server RHEL 7 running Oracle 19.3 APEX
- 4. Ansible APEX Restores - Prerequisites • ssh equivalence from control server to source and target • root is used for setting yum related ansible packages in source/target • oracle is used for running refreshes • ssh equivalence from Source and Target Server for oracle user • Oracle Homes installed in Source and Target server • The Lab Environment used the same Oracle Home folder set up in source/target
- 5. Ansible APEX Restores - Prerequisites Ansible Control Server Source Server ( running Oracle APEX ) Target Server • Ansible Installation • Playbooks • Ansible Installation • Local Scripts • Ansible Installation • Local Scripts
- 6. Ansible playbook tags • Tags are various sections of ansible playbooks which are utilised in this lab to ensure any particular section of the playbook can be run independently. • Tags used in the playbook are in the following order - source_checks -- Sanity Tests of source - source_db_backup -- RMAN Backup of Source - kick_rsync -- rsync of RMAN backups from source to target - source_apex_backup -- apex backups and scp from source to target - target_cleanup -- Clean up instances to refresh in target - target_db_restore -- RMAN Duplicate using backups from source - target_apex_restore -- Perform Apex Restores
- 9. The Inventory Ansible Control Server Source Server ( running Oracle APEX ) Target Server • Ansible Installation • Playbooks • Ansible Installation • Local Scripts • Ansible Installation • Local Scripts Ansible Control Server Config / Inventory
- 10. THE GOAL ?? A Sample Application created in source and can be seen in http://192.168.29.243:8080/apex - Goal is to run the Apex application in target http://192.168.29.244:8080/apex by performing Ansible Automation
- 11. Lets run the playbook # time ansible-playbook -u oracle ora_dup_restore_v1.yml The refresh completes in approx 23 mins
- 12. APEX is restored in http://192.168.29.244:8080/apex and the sample application created is now visible in the target
