• Dr. Frank Munz • Founded munz & more in 2007 • 15 years Oracle WebLogic and Middleware • Consulting and High-End Training • Three Oracle / Cloud books • @frankmunz on Twitter 3 Who’s That Other Guy? Dave Cabelus • WebLogic Server Product Manager since 2005 • Expertise in many areas of WebLogic Server • 8th consecutive year at OpenWorld • Follow Dave on Twitter at @dave_cabelus, videos at www.youtube.com/user/OracleWebLogic

• WebLogic 12.2.1 supports JDK 8 as runtime • Startup scripts work out of the box (permspace is removed in JDK 8) • Coherence 12.2.1uses JDK 8 language features in a distributed, lazy way • JDK 8u40 introduced resource management used by WebLogic multitenancy with G1 GC java -XX:+UnlockCommercialFeatures -XX:+ResourceManagement munz & more #8 #2 Java EE 7 Java EE 7

Every developer wants to use it! Improved or new standards in Java EE 7: • EJB 3.2 • Servlet 3.1 • JDBC 4.0 • WebSockets, JAX-RS 2.0, JSON-P 1.0 • Batch 1.0 • JMS 2.0 Tip: Learn about Java EE 7 • Concurrency Utilities 1.0 http://de.slideshare.net/glassfish/fifty-feature-of munz & more #10 Recommendation

You can revert production mode from console

munz & more #15 #5 Deployment Parallel Deployment

WebLogic 12.2.1 provides parallel deployment

• Multiple applications -> OFM • Single application with multiple modules

Across Modules in Across • Applications across Applications Applications multiple partitions Parallel Available in New in Prepare WebLogic 11g WebLogic 12.2.1

Parallel New in New in munz & more Activate WebLogic 12.2.1 WebLogic 12.2.1 #6 Elastic Cluster Elastic Cluster

WebLogic 12.1.2: Dynamic Cluster config WebLogic 12.2.1: Elastic Cluster runtime + pre / post scaling callout to scripts

How to scale? • Console • WLST • REST • Policy/Action • Calendar based munz & more #19 #7 JMS JMS

• JMS 2.0 support • Elastic JMS scales with elastic cluster • Simplified HA Configuration: WebLogic 12.2.1 JMS restrictions are removed • Default CX-factory required per Java EE 7: java:comp/DefaultJMSConnectionFactory resolves to weblogic.jms.XAConnectionFactory munz & more #21 #8 WLST New Command for Scaling

WLST command to scale dynamic cluster: scaleUp/Down ( clusterName, How many servers to numServers, add or remove [updateConfiguration], [block], [timeoutSeconds], ) munz & more #23 #9 WLDF 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 (policies) with configurable parameters munz & more #25 Smart rules:

Predefined policies with open parameters

munz & more #26 #10 RESTful Management 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)

munz & more #28 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 <-> Jolokia) • Used throughout WebLogic documentation munz & more #29 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

munz & more #30 Tech Details 2

• URL format has changed: …/wls/… was WebLogic 12.1.3, now: /management/weblogic/latest/…

• Edit sessions implicit: POST in /edit Or create manually with /edit/changeManager/ startEdit|cancelEdit|activate munz & more #31 CRUDQ Read

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/late st /domainRuntime/serverLifeCycleRuntimes/ surf1?links=none&fields=name,state

Response: { "name": "surf1", "state": "RUNNING" } munz & more #33 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 \ http://localhost:7001/management/weblogic/latest /edit/servers

munz & more #34 Create Form

Request create form (note, WebLogic 12.1.3 used HTTP OPTION)

GET http://localhost:7001/management/weblogic/latest /edit/serverCreateForm

munz & more #35 Update

Update server surf7, with curl curl ... -d "{ listenPort: '9999' } " -X POST \ http://localhost:7001/management/weblogic/la test/edit/surf7

munz & more #36 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 http://localhost:7001/management/weblogic/late st/edit/servers/surf7 munz & more #37 Query

Single bulk request queries to select and return specific subsets of tree.

POST http://localhost:7001 /management/weblogic/ latest/domainRuntime/ search munz & more #38 Take Aways

• HTTP OPTION (WLS 12.1.2) is currently not used -> …RequestForm • Modifying a read-only value is silently ignored (per design) • CREATE requires X-Requested-By header, to prevent CSRF (cross-site request forgery) • Most other headers are not mandatory

munz & more #39 #11 Docker WebLogic in a Docker Container Adrian Cockroft Netflix

“Docker wasn’t on anyone’s agenda for 2014. It’s on everyones roadmap for 2015.” Why Docker

• Because the whole world is talking about it J • Light-weight isolation technique • Solves "Worked for me" issue: Dev to prod, and on-premise to cloud • Supported by Oracle for WebLogic 12.2.1

Traffic WebLogic Server (JVM) Director Database

• Security: Security realm per partition • Life Cycle: Start / stop, debug flags • Data / Traffic: separate JNDI tree, data sources, (pluggable) DBs • Runtime: Ressource consumption manager

munz & more #49 Resource Consumption

Resources: You can Recourses: define multiple policies

munz & more #50 Use Cases

• Pack friendly domains together • Don't pack dev, test, and int together <-> one debug port per JVM etc. • How about: blue / green deployments using partitions and elasticity together?

munz & more Image Source: Fowler #51 Some more Take Aways

• MT best used with FMW Control (separate domain template) – Can you see the trend away from admin console? – FMW Control works with 'restricted JRF' -> No database needed (unlike OSB, SOA Suite etc.) • MT requires separate license, WebLogic Suite and EE allow 1 partition • No thread dumps per partition
