1. Java Cloud Service & WLS 12c What You Should Know OTN LatAm Tour / DOAG 2017 Dr. Frank Munz munz & more
2. •Founded munz & more in 2007 •> 15 years Middleware, Cloud, and Distributed Computing •Consulting and High-End Training •Wrote two WebLogic and a Cloud book Dr. Frank Munz @frankmunz
3. #1 WebLogic 12c
4. New in WebLogic 12.2.1 1. JDK 8 2. Java EE 7 3. IDE 4. Console 5. Deployment 6. JMS 7. Cluster 8. WLST 9. WLDF 10. REST 11. Docker 12. Multi Tenancy 13. ZDT 14. Java CloudService @frankmunz
5. A Whirlwind Tour… More details in this WebLogic 12c presentation @frankmunz https://www.slideshare.net/FrankMunz1/12-things-you-should-know-about-weblogic-server-1221-oow2015
6. WebLogic Multi Tenancy: Isolation Tenants within a domain are isolated: • Runtime: JDK: heap, CPU • Security: realm, user • Admin: life cycle, roles • Data / traffic: JNDI, JDBC,Coherence, requests @frankmunz
7. NO Vendor Lock-In with Docker Supported by every major cloud provider: @frankmunz On premise -> all clouds Docker Registry Container Service EC2 Container Service Google Container Engine Azure Container Service Bluemix Containers
8. RESTful Admin Get server name and state of managed server with name surf1 via admin server GET (e.g. via web browser) http://localhost:7001/management/weblogic/latest /domainRuntime/serverLifeCycleRuntimes/ surf1?links=none&fields=name,state Response: { "name": "surf1", "state": "RUNNING" } @frankmunz
9. Elastic Cluster WebLogic 12.1.2: Dynamic Cluster config WebLogic 12.2.1: Elastic Cluster runtime + pre / post scaling callout to scripts @frankmunz How to scale? • Console • WLST • REST • Policy/Action • Calendar based
10. ZDT: Rollout Oracle Home https://community.oracle.com/docs/DOC-996731 @frankmunz
11. #2 Oracle PaaS
12. Know The Essential Cloud Services ACCS JCS OCCS Deploy compiled Java, Python, Ruby code. New: Java EE, Go JSON file: start cmd Deploy Java EE module, JMS, JDBC, XA. + db and storage Deploy (stack of) Docker containers Language container as service WebLogic as Service Docker container as Service Oracle Container CS Java CS Application Container CS @frankmunz
13. #3 Prerequisites for JCS
14. Prerequisites • Write down all the passwords (they have different requirements) • ID domain • Storage container name • Use lower case emails for user names Keep the first temp password: If you change from classic to bare metal you need it @frankmunz
15. Prerequisites JCS will never work, unless you … 1. Set replication policy for storage 2. Create DB as a service for JCS 3. Create JCS @frankmunz
16. #4 (1) Replication Policy
17. Go to Storage & Set Policy @frankmunz You will only see this screen only once! Not setting the policy causes all kind of weird issues
18. Prereq: Set Replication Policy Details: https://docs.oracle.com/en/cloud/iaas/stora ge-cloud/cssto/selecting-replication-policy- your-service-instance.html Customer feedback: Oracle should set replication with working default @frankmunz
19. #5 (2) DB
20. Prereq: Create DB as Service A DB is mandatory for JCS @frankmunz Define DB pwd Specify Cloud log-in creadential Create Storage Container
21. Storage Container Correct syntax / name of storage container: Storage-IDENDITYDOMAIN/yourContainerName @frankmunz You create it once (with the DB). Later specify it at JCS configuration
22. Identity Domain Tip: Always save your Cloud Welcome Email @frankmunz ABCDomain
23. In the Same Email: Data Center Most OPC links DC agnostic, but storage is not: @frankmunz
24. Resend Welcome Email @frankmunz
25. Wait Until DB is Created @frankmunz Customer feedback: If JCS requires DB, why is it not automatically created?
26. #6 (3) JCS
27. @frankmunz
28. Create JCS @frankmunz Define WLS pwd Specify DB log-in details: ‘sys’ + credential DB create NOT welcome1 !! Specify Storage & log-in Details Storage admin
29. JCS is Created @frankmunz
30. #7 Access Admin Console
31. When you create a JCS @frankmunz
32. … you will likely forget the following: @frankmunz (Unfortunate) Default Setting: NO admin console but sample apps
33. #8 Access Rules
34. To the Rescue: Access Rules @frankmunz Re-enable Admin Console
35. #9 Deployments
36. Deployment Done via WebLogic console. @frankmunz
37. WebLogic Admin Console @frankmunz
38. #10 Port Mappings
39. Port Mapping Why you can access your deployment in most demos ‘without’ specifying the port @frankmunz
40. #11 Elasticity
41. Elasticity @frankmunz
42. Scale Out @frankmunz
43. Auto Scaling @frankmunz
44. #12 Patching
45. Patching @frankmunz
46. #12 Backups
47. Backups @frankmunz
48. #12 More Lessons Learned
49. There is more • OTD as frontend recommended • JCS comes with default certificates -> not suitable for production • Follow SOA CS Disaster Recovery Guide @frankmunz http://www.oracle.com/technetwork/database/availability/maa-soacs-dr-3125213.pdf
50. #13 ACCS Alternative
52. ACCS • Polyglot: Java, Java EE and node.js, PHP, Python, Go and Ruby • Java: Upload compiled zipped Java classes + JSON file with start command • Java EE option is WebLogic – No domains – No cluster – Single admin servers with LB frontend @frankmunz
53. #14 Spring Boot
54. Spring Boot • Not WebLogic or Java EE compatible • Not standard, but often used • It’s a fat jar • Runs in Oracle ACCS and AWS Beanstalk • Even with Kotlin @frankmunz http://www.munzandmore.com/2017/ora/kotlin-spring-boot-aws-beanstalk-oracle-cloud
55. #15 Developer CS
56. 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 @frankmunz Free development tooling in cloud

59. @frankmunz
60. Key Take-Aways Make sure to understand • JCS is WebLogic as a Service J • Dependencies with Storage and DB CS L • Storage Container name L • Little gotchas (admin console disabled) K • Port mappings • ACCS for polyglot, lightweight and Java EE J @frankmunz
