12 things, no agenda ☺

#0 ... lots of changes

#1 OUI / opatch

opatch  for  WLS  

New Installer

•  OUI – consistent with OFM and Oracle DB

•  Java is not included

•  No console mode anymore -> silent mode with response file

Other  options:  Vagrant  with  Chef  or  Puppet,  maven  and  even  Docker  

java –jar fmw12.1.3.0.0_wls.jar –silent –responseFile fullPathToRespFile –invPtrLoc /etc/oraInst.loc

munz & more #10  

The oraInst.loc File

oraInst.loc points to product inventory:

location depends on OS, e.g. OS X:

/var/opt/Oracle

munz & more #11  

Prerequisite Checks

munz & more #12  

Prerequisite Checks

•  CPU with 0 MHz ?! -> wrong BIOS selection in Virtual Box

•  swap enabled ?

•  /tmp on tempfs ? check size in /etc/fstab

•  Ignore result of check (NOT recommended): -ignoreSysPrereqs

munz & more #13  

opatch

•  Located in WEBLOGIC_HOME/Opatch •  Uses oraInst.loc •  opatch uses ORACLE_HOME variable

make sure it does not conflict with ORACLE_HOME of installed DB -> different installation user

munz & more #14  

#2 Domain Wizard

config.sh

domain location includes domain name

-Dcom.oracle.cie.config.showProfile enables Compact/Expanded Domain Topology Selection (mainly for OFM)

munz & more #16  

config.sh Oracle  doc  WLS  12.1.1  

Instead use WLST, unpack, maven, …

munz & more #17  

#3 Per Domain

Node Manager Per  Domain  NM  

Per Domain Node Manager •  Easier setup •  Config and logs part

of domain directory •  Uses SSL per default •  unpack recreates

demo certs •  Startscript:

DOMAIN_HOME/bin/startNodeManager.sh

munz & more #19  

Per Domain Node Manager

•  DOMAIN_HOME/nodemanager contains nodemanager.properties and nodemanager.domains

•  Per machine NM still possible: startNodeManager.sh in WL_HOME/server/bin

munz & more #20  

Certificates

Demo Cert per Domain under DOMAIN/security

���

keytool –list -storepass DemoIdentityKeyStorePassPhrase –v -keystore DemoIdentity.jks

Certificate  contains  hostname.    Unpack  recreates  Demo  Cert  with  hostname  of  new  host.  

munz & more #21  

3 Simple Steps

1.  Start Node Manager

2.  Create Machine

3.  Create Servers / Dynamic Cluster and assign machine

Then use admin server web console to start managed servers

munz & more #22  

New in WLS 12.1.3

Some nodemanager.properties names changed, old names are deprecated now: StartScriptEnabled -> weblogic.StartScriptEnabled also StartScriptName, JavaHome, StopScriptName, UseMACBroadcast, …

munz & more #23  

#4 Server Templates

Server  Templates  

Server Templates

st=create('myTemplateName','ServerTemplate') MBean type ServerTemplate with name myTemplate has been created successfully.

st.setStartupTimeout(300)

munz & more #25  

Config Hierarchy

•  Default Server Settings (value not specified)

•  can be overwritten by Server Template Settings

•  can be overwritten by Individual Server Configuration

munz & more #26  

#5 Dynamic Cluster

Dynamic  Cluster  

Dynamic Cluster

munz & more #28  

How Dynamic Is It?

•  Only configuration is dynamic

•  Must start servers manually (dynamic runtime is still missing)

•  To decrease cluster size: stop last server, then decrease number of dynamic servers configuration

•  Server Migration for dynamic and mixed cluster supported with WLS 12.1.3

munz & more #29  

#6 Unicast Groups

Unicast  Groups  

New Unicast Groups

Implementation in WebLogic 12.1.3 changed:

•  Fixed max # of groups is 10

•  Groups can by asymmetric

•  Servers are consistently placed in groups based on hash of server name

munz & more #31  

Classic Cluster Size 3

#32  

Dynamic Cluster Size 15

#33  

#7 Cluster Targeted JMS

Cluster  Targeted  JMS  

Easier JMS

•  Target JMS server to cluster (also to dynamic cluster!)

•  Persistent stores are provisioned automatically

•  Then target distributed queue to JMS server

munz & more #35  

Elastic JMS in WLS 12.1.3

•  Supports whole server migration (WSM) with WebLogic 12.1.3

•  Note, there are some restrictions: No Unit-of-Order, no Unit-of-Work, no service migration…

see also https://blogs.oracle.com/WebLogicServer/entry/introducing_elastic_jms

munz & more #36  

#8 Java Mission Control

 JMC  and  JDBC  

Java Mission Control

Java Mission Control comes with JDK 1.7.0_40+

•  Free for development

•  Ported over from JRockit

•  Detailed, graphical views

-> start with jmc

munz & more #38  

Monitoring JDBC

Java Mission Control

To enable JMC, you need the following switches

JAVA_OPTIONS=” -XX:+UnlockCommercialFeatures

-XX:+FlightRecorder" e.g. configure settings in DOMAIN_HOME/bin/setUserOverrides.sh

Configure  WebLogic    Domain-­‐Wide  Settings  here  

munz & more #40  

#9 WLDF Built-in

Modules

WLDF Diagnostic Module

WLDF Modules now easier: based on built-in

“Low” enabled by default in production mode

munz & more #42  

Predefined Watches (Medium)

munz & more #43  

#10 RESTful

Management  RESTful  Config  Part  I  /  Part  II  

REST Management API

API has changed in WLS 12.1.3

-> Supports configuration changes:

•  Server lifecycle

•  For resources, eg. JDBC data source: create, stop, test, …,

•  Deployments

munz & more #45  

REST Management API

Example http GET: http://localhost:7001/ management/wls/ latest/deployments/ application

munz & more #46  

http OPTIONS with /management/wls/latest /datasources returns the default JSON structure for data sources

-> Fill in the values and send it back to server

Generate Template / OPTIONS

munz & more #47  

Create Data Source / POST

POST JSON data with all mandatory values to /management/wls/latest/datasources returns:

munz & more #48  

Limitations

Some resources not supported yet in 12.1.3

•  JMS

•  Work Managers

•  WLDF

munz & more #49  

#11 Development

 Oracle  White  Paper  

Partial Support of Java EE 7 APIs

WebLogic 12.1.3:

•  Java API for WebSocket 1.0 NEW

•  JSON-P 1.0 NEW

•  JAX-RS 2.0 with lib deployed UPDATE JAX-RS 1.1. OOTB

•  JPA 2.1 with lib deployed UPDATE JPA 2.0 OOTB

deploy  /wlserver/common/deployable-­‐libraries/  jax-­‐rs-­‐2.0.war    

deploy  2  shared  libs  

munz & more #51  

New Maven Goal

•  25 maven goals for WebLogic 12.1.3

•  WebLogic 12.1.3: New maven WLST goal: wlst-client -> does not require local WebLogic installation for WLST online commands.

munz & more #52  

One more thing.

#12 Yes, Docker!

 WLS  and  Docker  

WebLogic  in  a  Docker  Container  

What is Docker?

•  NOT Now officially supported by Oracle

•  Sandboxing based on Linux containers

•  Layered images

•  Public / private repository

•  Containers start up in milliseconds

•  Portable standard -> runs on Linux, also in clouds
