#1

JDK 8

JDK 8

• 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 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• Concurrency Utilities 1.0munz & more #10

Elastic Cluster

Elastic Cluster

WebLogic 12.1.2: Dynamic Cluster configWebLogic 12.2.1: Elastic Cluster runtime

+ pre / post scalingcallout to scripts

munz & more #19

How to scale?• Console• WLST• REST• Policy/Action• Calendar based

#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/DefaultJMSConnectionFactoryresolves to weblogic.jms.XAConnectionFactory

munz & more #21

#8

WLST

New Command for Scaling

WLST command to scale dynamic cluster:

scaleUp/Down (clusterName, numServers, [updateConfiguration], [block], [timeoutSeconds],

) munz & more #23

How many servers to add or remove

#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

munz & more #26

Smart rules:

Predefined policieswith open parameters

#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 /editOr create manually with /edit/changeManager/startEdit|cancelEdit|activate

munz & more #31

CRUDQ

ReadGet 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" }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/latest/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 DELETEhttp://localhost:7001/management/weblogic/latest/edit/servers/surf7munz & more #37

Query

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

POSThttp://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

WebLogicin a DockerContainer

“Docker wasn’tonanyone’sagendafor2014.It’soneveryones roadmapfor2015.”

AdrianCockroftNetflix

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

Isolation: 4 Areas

• Security: Security realm per partition

• Life Cycle: Start / stop, debug flags

• Data / Traffic: separate JNDI tree, data sources, (pluggable) DBs

• Runtime: Ressource consumption manager

Resource Consumption

Resources:

munz & more #50

Recourses:You can definemultiple policies

ImageSource:Fowler

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 usingpartitions and elasticity together?

munz & more #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
