5 Introduction > What are we calling Cloud? > Why speaking about patching? > Oracle Database patching Automate Patching for Oracle Database in your Private Cloud Page 5

6 Introduction What are we calling Cloud? Is Cloud just a marketing/buzz word? > Cloud mostly means operating as a Service > PaaS, DBaaS, aso How can we define Cloud? > Graphical Interface as a portal > Automation Who said autonomous? > Back-charging Pay as you use My personal Cloud definition > Operate your system so the client sees it as a service Page 6

7 Introduction Why speaking about patching? Reminder: the WannyCry case > Microsoft released security patch on March 2017 > The ShadowBrokers disclosed vulnerability details in April > Worldwide attack started on 15 May 2017 Does it really matter? > Some UK hospitals were impacted to the point some operations were rescheduled > Renault had to stop production sites several days due to the attack > Businesses were impacted The security patch was available since 2 months before a global attack > Time window to test/validate/apply patches is reducing Page 7

8 Introduction Oracle Database patching Oracle Critical Patch Update program > Collection of security fixes for Oracle products > Released every quarter around 17 th : January, April, July, October > Security alert for critical security issues: 2 in November 2017 > Available on OTN: Database patching is evolving > CPU/SPU or PSU in Oracle Database 11g > PSU / Proactive Bundle Patch for Oracle Database 12c R1 > RU / RUR starting in Oracle Database 12c R2 Use favorites in My Oracle Support > Doc ID : Download reference for Oracle DB patches > Doc : Master note about patch program (previously recommended patches) Page 8

9 Patching automation with Ansible > Introduction to Ansible > Ansible language > Ansible tasks, playbook and roles Automate Patching for Oracle Database in your Private Cloud Page 9

10 Patching automation with Ansible Introduction to Ansible Ansible is a simple automation language > Open source automation tool > Designed for multi-tier deployment > Agentless Ansible relies on SSH and Python > Push based > Tasks oriented easy to read Ansible is very popular > Extra-module available on Github: > Lots of existing code available on Ansible Galaxy: Non exhaustive use cases > Configuration > Provisioning Page 10

11 Patching automation with Ansible Introduction to Ansible Ansible allows running ad-hoc commands against host $ ansible dbinstances -m ping DB1 SUCCESS => { "changed": false, "failed": false, "ping": "pong" } Ansible gather facts about your systems > You can dynamically adapts your code based on variables $ ansible DB1 -m setup DB1 SUCCESS => { "ansible_facts": { "ansible_architecture": "x86_64", "ansible_bios_version": "VirtualBox", "ansible_distribution": "OracleLinux", "ansible_distribution_version": "7.4", } } Page 11

12 Patching automation with Ansible Ansible language Ansible code is written in YAML > Human readable way to represent serializable data > Close to JSON and Python name: Install Oracle binaries hosts: dbinstances vars_files: - vars/psu_{{ oracle_version }}_{{ psu_release }}.yml roles: - role: deploy_oracle_home YAML pitfalls > Use indentation but do NOT support tabulation > Create lists be careful with : too Page 12

13 Patching automation with Ansible Ansible language Ansible is declarative / desired state based > No need for you to test the result > Ansible will assure the declaration is true > Modules should be idempotent Running multiple time should be the same as running only once Ensure the user oracle exists with the required groups - name: Prepare user oracle user: name: oracle password: '{{ oracle_user_pwd }}' groups: - dba - vboxsf Page 13

14 Patching automation with Ansible Ansible tasks, playbook and roles Playbooks are composed of 1 or more plays > A play is a YAML document describing tasks > A play allows to group actions to certain hosts > Multiple plays are useful for multi-tiers deployment Page 14

15 Patching automation with Ansible Ansible tasks, playbook and roles Playbooks run against hosts > Need to declare your components in an inventory > Inventory can be dynamically generated Ansible roles allows to create deployment units > Roles contains tasks but also variables > Easily create reusable playbooks with variables > Roles and directory layout helps to organize the code. ansible.cfg deploy_oracle_home.yml inventory Dev group_vars dbservers default_ora_config host_vars DB1 hosts roles create_db tasks main.yml Page 15

16 Demo 1 > Quick word about Vagrant > Test infrastructure Automate Patching for Oracle Database in your Private Cloud Page 16

17 Demo Quick word about Vagrant Vagrant is a tool for building virtual machines > Open source tool > Easy way to create reproducible environment > Support several providers (VirtualBox, VMware, AWS, ) > Support provisioning tool like Ansible, Chef or Puppet Vagrant is used to provision standard Linux servers > Oracle Linux boxes available at Page 17

19 Conclusion Automate Patching for Oracle Database in your Private Cloud Page 19

20 Conclusion Automation increases your security > Develop once, run many in standard way even in parallel > Reduce human errors Automation allows you to commit your infrastructure > Developers commit the business code > Save the code helping to run the code > Playbooks/recipes can be saved in source control and versioning tool (Git, SVN, ) Page 20

21 Conclusion What s the link with the Cloud? Once playbooks are ready, create your portal to run them and build your Cloud > Ansible Tower > Ansible AWX > Jenkins > Semaphore Ansible integrates well if you go for public Cloud > Ansible has modules to manage/provision AWS EC2 instances > Inventory can be dynamically generated > Maintain your Cloud environment at same level dbi services Page 21
