6 12 new things, no agenda J

7 #0... download today!

8 #1 JDK 8

9 JDK 8 WebLogic supports JDK 8 as runtime Startup scripts work out of the box (permspace is removed in JDK 8) JDK 8u40 introduces resource management used by WebLogic multitenancy with G1 GC java -XX:+UnlockCommercialFeatures -XX:+ResourceManagement #9

10 #2 Java EE 7

11 Java EE 7 Every developer want to use it! Small subset of improved standards: EJB 3.2 Servlet 3.1 JDBC 4.0 WebSockets, JAX-RS 2.0, JSON-P 1.0 Batch 1.0 JMS 2.0 Concurrency Utilities 1.0 Tip: Learn about Java EE 7 h\p://de.slideshare.net/glassfish/fiby-feature-of #11

12 Recommendation #12

13 #3 IDE Integration

14 IDE Support NEW! wlserver/server/bin/eclipse.sh NetBeans 8.1 RC / Dev Build works with WebLogic JDeveloper available for OFM Eclipse net (and package) installer -> easy OEPE download & install #14

15 #4 Console changes J

16 Production Mode You can revert production mode from console #16

17 #5 Deployment

18 Parallel Deployment WebLogic provides parallel deployment Multiple applications Single application with multiple modules Applications across multiple partitions Parallel Prepare Across Modules in Applica6ons Available in WebLogic 11g Across Applica6ons New in WebLogic Parallel Ac6vate New in WebLogic New in WebLogic

19 #6 Elastic Cluster

20 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 #20

21 #7 JMS

22 JMS JMS 2.0 support Elastic JMS scales with elastic cluster Simplified HA Configuration: WebLogic JMS restrictions are removed Default CX-factory required per Java EE 7: java:comp/defaultjmsconnectionfactory resolves to weblogic.jms.xaconnectionfactory #22

23 #8 WLST

24 New Command for Scaling WLST command to scale dynamic cluster: scaleup/down ( ) clustername, numservers, [updateconfiguration], [block], [timeoutseconds], How many servers to add or remove #24

25 #9 WLDF

26 WLDF Watches and notifications are replaced by policies and actions Additional 4 WLDF actions scale up / down REST Script Diagnostic image files are.txt or.xml Prepackaged smart rules with configurable parameters #26

27 Smart rules: Predefined policies with open parameters #27

28 #10 RESTful Management

29 Why REST? Simplicity Language agnostic No JVM, no WebLogic on client side <->JMX Easy to tunnel through firewalls: HTTP Current tech trend (eg. mobile dev) #29

30 RESTful Management New generic REST implementation: Full support for all resources (also JMS etc.) RESTful management is turned on per default Available on admin and managed Servers Modelled after WLST structure (real MBean names not required) Used throughout WebLogic documentation #30

31 Tech Details 1 What you can access: domain serverconfig, domain serverruntime, edit [exclude]fields=field1, field2 [exclude]links=none, links=rel interaction=async-polling sync #31

32 Tech Details 2 URL format has changed: /wls/ was WebLogic , now: /management/weblogic/latest/ Edit sessions implicit: POST in /edit Or create manually with /edit/changemanager/ startedit canceledit activate #32

33 CRUDQ

34 Read Get server name and state of managed server with name surf1 via admin server GET (e.g. via web browser) latest /domainruntime/serverlifecycleruntimes/ surf1?links=none&fields=name,state Response: { "name": "surf1", "state": "RUNNING" } #34

35 Create Short way to create server surf7, with UNIX curl curl v --user weblogic:welcome1 \ -H X-Requested-By:MyClient \ -H Accept:application/json \ -H Content-Type:application/json \ -d "{ name: 'surf7' } " -X POST \ /edit/servers #35

36 Create Form Request create form (note, WebLogic used HTTP OPTION) GET /edit/servercreateform #36

37 Update Update server surf7, with curl curl... -d "{ listenport: '9999' } " -X POST \ latest/edit/surf7 #37

38 Delete Delete server surf7: curl v --user weblogic:welcome1 \ -H X-Requested-By:MyClient \ -H Accept:application/json \ -H Content-Type:application/json \ X DELETE latest/edit/servers/surf7 #38

39 Query Single bulk request queries to select and return specific subsets of tree. POST /management/ weblogic/latest/ domainruntime/search #39

40 #11 Docker

41 WebLogic in a Docker Container

42 Virtualization vs. Isolation App Linux App Win VirtualBox Mac OS / Win App Win Appl 1 Solaris Appl 1 Linux Appl 1 Win OVM / VmWare ESX / Xen ejb.jar a.war tools WebLogic JDK x.py Jython Linux + Docker y.jar Hardware Hardware Hardware Desktop VirtualizaFon: type 2 hypervisor = with host OS Server VirtualizaFon type 1 hypervisor = on bare metal Docker container in Linux with own FS, network stack / IP address, process space and resource limits #42

43 Docker Docker is not a a.war ejb.jar lightweight VirtualBox WebLogic tools x.py Jython y.jar - it's about isolation. JDK Containers run on Linux + Docker Linux kernel of host Hardware -> Containers are visible on host #43

44 Docker Container Isolated runtime of Docker image Starts up in milliseconds Sandboxing uses Linux namespaces and cgroups -> isolated part of your Linux Open Container Standard / Linux Foundation docker run -d p 8080:9999 fmunz/micro #44

45 solves the Worked For Me! issue OS ufls, JDK, patches, database driver, libs, appserver, domain, deployment, tools, scripts ProducFon dockerize it! Docker OS tools, JDK, patches, database driver, libs, appserver, domain, deployment, tools, scripts IntegraFon, Performance, Acceptance TesFng Docker Registry You can pass environment variables for specific settings e.g. in prod #45

46 Docker Registry what should be your biggest nightmare: unknown and unofficial images (>14000)

47 Docker in the Cloud? Supported by every major cloud provider: Docker Registry On premise -> all clouds #47

48 Demo?

49 What Do You Get? NOT WebLogic from Docker registry NO automatic build via github Github repo with scripts to set up WebLogic on Oracle Linux in Docker Dev or generic distribution Docker is a supported environment for WebLogic / #49

50 Docker Style Independent, standalone WLS domain Microservices style architecture Just add your favorite Docker cluster manager OS tools, JDK, database driver, libs, appserver, single domain (admin server only), deployment, tools, scripts #50

51 The WebLogic Way $docker run -d -p 8001: name=wlsadmin fmdom1 startweblogic.sh $docker run -d --link wlsadmin:wlsadmin fmdom1 createserver.sh or createmachine.sh or startnodemanager.sh port 8001 IP:port 7001 JDK, WLS, Domain startweblogic.sh starts AdminServer wlsadmin --link JDK, WLS, Domain createserver.sh: creates machine/nm, starts NM, creates manserv, starts manserv Managed Servers connect to admin due to --link: /etc/hosts wlsadmin 31a1baaf #51

52 Oracle Whitepaper WebLogic on Docker Containers Docker book by J. Turnbull (Docker 1.8) #52

53 Facts to Know Oracle supports WebLogic on Docker Docker networking is still experimental -> limitations for cross-machine deployments Docker cluster managers are still evolving: Docker Swarm, Kubernetes, Apache Mesos with Marathon, AWS ECS, CloudFoundry, etc. #53
