- 11. #1 Oracle PaaS
- 12. Know The Essential Cloud Services ACCS JCS OCCS Deploy Java, Python, Ruby code + JSON file: start command Deploy Java EE module, JMS, JDBC, XA. Deploy (stack of) Docker containers Language container as service WebLogic as Service Docker container as Service
- 13. #2 Developer CS
- 14. Developer CS Cloud native SDLC • Connects to github • Includes – maven – Hudson – Wiki pages – Jira like ticket system • Ready for testing • Deploys to JCS, ACCS, Mobile CS munz & more #14 Free development tooling in cloud
- 15. Developer CS munz & more #15
- 17. Prerequisites JCS will never work, unless you … 1. set replication policy for storage 2. Create DB as a service for JCS 3. Create JCS -> Write down all the passwords (which have different requirements), ID domain, and storage container name
- 19. Go to Storage & Set Policy munz & more #19 You will only see this screen only once! Not setting the policy causes all kind of weird issues
- 20. Prereq: Set Replication Policy Details: https://docs.oracle.com/en/cloud/iaas/stora ge-cloud/cssto/selecting-replication-policy- your-service-instance.html
- 21. #5 (2) DB
- 22. Prereq: Create DB as Service A DB is mandatory for JCS munz & more #22 Define DB pwd Specify Cloud log-in creadential Create Storage Container
- 23. Storage Container Correct syntax / name of storage container: Storage-IDENDITYDOMAIN/yourContainerName munz & more #23 You create it once (with the DB). Later specify it at JCS configuration
- 24. Identity Domain Tip: Always save your Cloud Welcome Email munz & more #24 ABCDomain
- 25. In the Same Email: Data Center Most OPC links DC agnostic, but storage is not: munz & more #25
- 26. Resend Welcome Email munz & more #26
- 27. Wait Until DB is Created munz & more #27
- 28. #6 (3) JCS
- 29. munz & more #29
- 30. Create JCS munz & more #30 Define WLS pwd Specify DB log-in details: ‘sys’ + credential DB create NOT welcome1 !! Specify Storage & log-in Details Storage admin
- 31. JCS is Created munz & more #31
- 33. When you create a JCS munz & more #33
- 34. … you will likely forget the following: munz & more #34 (Unfortunate) Default Setting: NO admin console but sample apps
- 35. #8 Access Rules
- 36. To the Rescue: Access Rules munz & more #36 Re-enable Admin Console
- 37. #9 Deployments
- 38. Deployment Done via WebLogic console. munz & more #38
- 40. Port Mapping Why you can access your deployment in most demos ‘without’ specifying the port

- 50. Key Take Aways Make sure to understand • Java CS is WebLogic as a Service • Dependencies with Storage and DB CS • Storage Container name • Little gotchas (admin console disabled) • Port mappings • ACCS for polyglot, lightweight, non Java EE munz & more #50
