5 A Few Highlights More details in this WebLogic 12c presentation munz & more #5

6 WebLogic Multi Tenancy: Isolation Tenants within one domain have isolation Runtime: Security: Admin: Data / traffic: JDK, heap, CPU realm, user life cycle, roles JNDI, JDBC, Coherence, requests munz & more / globalcollect 2016

7 NO Vendor Lock-In with Docker Supported by every major cloud provider: Docker Container Service Docker Registry EC2 Container Service Google Container Engine On premise -> all clouds munz & more Azure Container Service Bluemix Containers #7

8 RESTful Admin: Read Get server name and state of managed server with name surf1 via admin server GET (e.g. via web browser) /domainruntime/serverlifecycleruntimes/ surf1?links=none&fields=name,state Response: { "name": "surf1", "state": "RUNNING" } munz & more #8

9 Elastic Cluster WebLogic : WebLogic : Dynamic Cluster config Elastic Cluster runtime + pre / post scaling callout to scripts How to scale? Console WLST REST Policy/Action Calendar based munz & more #9

10 ZDT: Rollout Oracle Home

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 Free setup and operations of development tooling #14

18 #3 Prerequisites for JCS

19 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

20 #4 Replication Policy (1)

21 Go to Storage & Set Policy You will only see this screen only once! Not setting the policy causes all kind of weird issues munz & more #21

22 Prereq: Set Replication Policy Details: ge-cloud/cssto/selecting-replication-policyyour-service-instance.html

23 #5 DB (2)

24 Prereq: Create DB as Service A DB is mandatory for JCS, but not for WebLogic 12c on-premises. Define DB pwd Create Storage Container Specify Cloud log-in creadential munz & more #24

25 Storage Container Correct syntax / name of storage container: Storage-IDENDITYDOMAIN/yourContainerName You create it once (for the DB). Later specify it at JCS creation munz & more #25

26 Identity Domain Always save your Cloud Welcome ABCDomain munz & more #26

27 Same Your Data Center Most OPC links DC agnostic, but storage is not: munz & more #27

28 Resend Welcome munz & more #28

29 Wait Until DB is Created munz & more #29

30 #6 JCS (3)

31 munz & more #31

32 Create JCS Define WLS pwd munz & more NOT welcome1!! Specify DB log-in details: sys + credential DB create Specify Storage & log-in details #32

33 JCS is Created munz & more #33

34 #7 Access Admin Console

35 When you create a JCS munz & more #35

36 you will likely forget the following: (Unfortunate) Default Setting: NO admin console but sample apps munz & more #36

37 #8 Access Rules

38 To the Rescue: Access Rules Re-enable Admin Console munz & more #38

39 #9 Deployments

40 Deployment Done via WebLogic console. munz & more #40

41 #10 Port Mappings

42 Port Mapping Why you can access your deployment in most demos without specifying the port

43 WebLogic Admin Console

44 #11 Elasticity

45 Elasticity munz & more #45

46 Scale Out 46

47 Auto Scaling

48 #12 Patching

49 Patching

50 #12 Backups

51 Backups

52 JCS Summary Saves you install time Nicely integrated with DB, ID etc. Clone environments ZDT patching Automated Lifecycle For Java and DB cloud Continuous Integration / Deliver Integration with Developer Cloud Service -> speed up and modernize environments munz & more #52

53 Key Take Aways Make sure to understand JCS is WebLogic as a Service the 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 #53
